BIO-RHASIL EV1060 Low Heat Generation Bio-based Silica EV Series

Transforming Tire Manufacturing through Practical Chemistry

Years of compounding experience in tire plants taught us some simple truths: summer roads punish rubber, electric drivetrains change heat profiles, and downtime chasing temperature problems eats up margins. Our team in silica manufacturing, with backgrounds in both process chemistry and real-world mixing, saw an urgent need. Replacing petroleum-based fillers with something from a renewable source always sounds nice in theory, but for us, the rubber hits the road in the mixer room. BIO-RHASIL EV1060 emerged from this hard-earned insight.

Real Benefits Born from our Own Production Floors

EV1060 isn’t just a new chemistry project — we set out to solve a stubborn problem in high-silica treads: heat. High temperatures during mixing and curing push compounding teams to cut cycle times, slow down throughput, or live with more scorch and rolling resistance than they’d like. The silica itself often contributes to heat generation, making the whole process harder to control. We looked at this from a practical standpoint — we run lines ourselves, and our own process engineers flagged the wasted energy and inconsistent compound properties.

By switching to a bio-based route, we harnessed agricultural byproducts (mainly rice husk ash in our case) and refined the precipitation process until we achieved a silica grade with lower reaction enthalpy. In every commercial trial we ran, compounder and mixer teams reported lower rotor temperatures at standard speeds using the EV1060, compared to conventional fossil-derived silica.

Performance through Lower Heat Generation

Mixing heat matters. We know because we've had to call electricians in for burnt-out motors or wait for cooling cycles ourselves. By producing a silica with inherently lower heat of mixing, EV1060 shrinks downtime risk and smooths out cycle-to-cycle results. In daily operations, this translates to more predictable Mooney viscosity, sharper batch consistency, and fewer surprises at the curing press.

Our lab teams and partnering compounding engineers documented mixing temperature reductions of 8-15°C, depending on the recipe and batch size. That didn’t just show up in reports — it shortened cooldown times and curbed heat-induced scorch. Less energy outlay during mixing also let us run batches at higher throughput without chasing hot spots or delayed-release behavior.

The environmental story holds up as well. Sourcing from plant-based feedstocks doesn’t mean sacrificing consistency, and now that grid energy rates keep climbing, trimming mixing energy outlays delivers direct operational savings.

The Bio-based Advantage without Trade-offs

Early bio-derived fillers often forced production and R&D teams to accept weaker mechanicals or fuss with compatibility agents. We refused to take shortcuts. Through years of equipment tweaks and refining surface chemistry, the EV1060 demonstrates full dispersion in both conventional and silane-coupled tire systems, and supports carbon-neutral claims many OE customers ask about. Under the microscope, you won't find excessive agglomeration, which saves headache on downstream quality control.

Rolling resistance—our field engineers’ top concern for electric mobility—improves measurably when EV1060 replaces fossil-based silicas at the same phr. Our best-case field tests show 5-8% lower rolling hysteresis, sometimes more, which translates to better tire rating scores and longer-lasting compounds, especially for heavy EV designs. We’ve proven the sidewall cracking and tread wear do not worsen with BIO-RHASIL’s finer particle grading, and in fact, our partner labs saw slightly tougher wet grip retention after 10,000 km fleet loops.

How Our Process Drives Value

Production at scale matters. We invested in continuous, automated reactors to keep batch-to-batch specs as tight as possible, especially targeting surface area and silanol group balance. Our chemist-led team doesn’t just monitor data; we shut down batches if pH, BET surface area, or structure move outside our defined windows. Each shipment follows internal grading standards born from years of feedback loop with tire developers and operators.

We keep carbon, sulfur, and trace metal impurities consistently under 100 ppm. Our silica morphology, shaped by tuned precipitation and post-treatment steps, gives you the rheology you want — and the dispersion profile your QA team needs. That practically eliminates excess corrections at the mill or unexpected failures in tensile or rebound tests.

Bio-based Raw Materials: Future-Ready, Supply Secure

EV1060 uses rice husk ash from regional sources, chosen for both availability and traceability. The global logistics shocks in recent years made it clear: you can’t bet on a stable supply of petro-based raw materials. The move to bio-based isn’t just about green labels; it keeps tire plants running when oil-derived stocks suffer spikes or interruptions. Traceability audits are simpler, documentation is backed by GPS-verified origin, and waste valorization closes a crucial loop for ESG reporting, giving procurement teams one less point of stress as customer expectations rise.

Direct Compatibility with Existing Equipment

We built the EV1060 grade so that plants don’t need to overhaul their current feeding, dispersing, or compounding setups. Based on our trials in Asia and Europe, both Banbury and intermeshing mixers take EV1060 straight without changes to feeding rate or equipment settings. Our teams worked the production lines ourselves when possible, making sure pneumatic conveyors, silos, and weigh feeders could switch in our product with no bridging or caking delays.

Moisture pick-up performance is kept in line with traditional grades, reducing the risks from high humidity storage conditions. Fines and dusting are minimized at source, so your operators spend less time cleaning, and plant air quality stays within workplace safety targets. We cataloged fewer mill roll delamination events in plants that switched over, and in longer trial runs, our QA teams flagged a reduction in rejection rates for air voids and compound speckling.

Supporting EV Tire Performance Demands

Electric vehicles stress tires in new ways. Instant torque shreds weak treads, and the weight of battery packs asks even more from corner compounds. We designed the EV1060 both to lower rolling resistance and to push wet grip scores higher. Internal road tests tracked by fleet operators logged better acceleration wear patterns, and our updated silica surface chemistry holds silane levels for better coupling, extending both heat and cold traction.

Some tire engineers worry about balancing tread wear against wet performance. On our test rigs, we balanced those properties through careful particle size and silanol control. Compared to traditional precipitated silicas, EV1060 lets developers meet or exceed VECTO and Green Tire labeling standards, with less need for recipe tuning.

EV manufacturers and tire producers ask about sound-dampening properties, since EV drivers notice tire noise more without an engine masking it. We see competitive performance in acoustic absorption, with graph-backed internal data showing roughly 3-5% better decibel dampening in treaded compounds, helping meet the most demanding OE sound criteria.

Finding Practical Solutions: Lessons from the Line

We believe insight doesn’t show up in boardroom metrics but on production floors. Our operators flagged that lower heat build-up during mixing often allowed them to extend equipment maintenance intervals, cutting unplanned downtime costs over the quarter. They also reported a smoother powder flow through automated feeders, where clogging shut workstations down with older grades.

Batch QA teams rely on repeatable rheology. Less heat spike means more consistent discharge viscosity, fewer “off-batch” errors, and less sorting of borderline lots. In multi-line plants, EV1060 helped synchronize shift schedules, which matters when production managers work double shifts to hit high-volume orders.

Compounders in both large and regional tire makers gave us feedback on color and transparency impacts in sidewall formulations. While conventional silicas tend to yellow over time at higher process temperatures, EV1060’s bio-based origin retains a whiter, brighter tone at equal curing conditions, reducing pigment adjustments and scrap.

The Sustainability Story: Real Environmental Impact

Building tires with a lower carbon footprint takes more than optimistic targets. Using agricultural waste as our silica source lets us close a waste loop for local rice growers, keeping ash out of landfills and transforming it into a functional, high-value raw material. This delivers direct carbon savings at the sourcing stage.

A certified life-cycle analysis shows a greenhouse gas reduction versus petroleum-based equivalents, measured cradle-to-gate. Tire OEMs report that switching to EV1060 helps them reduce their Scope 3 emissions without introducing risk to tire performance or QA yield rates. The fact that our process cuts grid energy demand every time a mixer starts up fits with the operational carbon reduction plans our partners are pressed to deliver.

Professional Support: Partnering for Problem-Solving

As hands-on chemical producers, we offer more than sales talk. Our tech teams routinely visit customer facilities, set up new trial protocols, and troubleshoot mixing or feeding hiccups. We’ve found that real process improvements come from working shoulder-to-shoulder with production and R&D teams, not from remote presentations. Every production challenge we help fix with EV1060 feeds back into our manufacturing playbook—ensuring the grade keeps evolving along with customer standards.

We work directly with procurement and QA departments, sharing both application notes and typical troubleshooting tips born from our own daily practice. If a trial batch shows unexpected results, our chemists audit batch records in parallel with your staff, digging for root causes rather than defaulting to generic explanations.

Meeting Tomorrow’s Regulatory and Market Challenges

Passing tougher global chemical regulations requires clean upstream sourcing, continuous composition control, and rapid adaptation when standards move. EV1060’s fully documented, bio-based sourcing streamlines audits. Customers report shorter delays in regulatory submissions for Green Tire certifications and new OE homologations.

End-of-life disposal is another growing concern for tire brands. The bio-derived composition makes it easier to qualify for advanced recycling pilot programs and state incentives designed to reward renewable content. Since the product avoids petroleum feedstocks, it aligns with rapidly tightening import controls in certain jurisdictions.

EV1060 in Action: Case Studies from Tire Compounds

A leading Asian tire manufacturer switched half its all-season line to EV1060 during a raw material shortage, and batch records tracked an average 12% reduction in mixer energy bills over six months. Quality control logs showed tighter control of crosslink density, mapping directly to lower field returns for heat-related failures on that line.

A European plant making specialty EV tires saw rotor temperature drop by nearly 10°C at their standard throughput after switching. Instead of lengthening mix times to avoid scorch, operations reported being able to push for faster cycles, beating productivity targets without tripping cure control alarms.

Compound adjustments also grew more predictable. Multiple tire makers confirmed that wet grip and abrasion retention stayed stable across a wider humidity and temperature range in storage, simplifying warehouse management.
