In the competitive landscape of rubber manufacturing, everyone is obsessed with CAPEX (Capital Expenditure). Factories spend millions on new internal mixers, twin-screw extruders, and automated lines to squeeze out a little more daily output.
But the smartest manufacturers know a secret: You don’t always need more machines to produce more. Sometimes, the bottleneck isn’t hardware; it’s chemistry.
At CEHNGDAHUILI, we have proven that optimizing just 0.1% of your formula—specifically your Anti-Scorching Agent (PVI/CTP)—can unlock double-digit efficiency gains.
The “Hidden Capacity” Paradox
Every rubber engineer faces the same limit: Heat History. To mix rubber faster, you generate more shear heat. If the heat gets too high, the compound scorches. So, you slow down the rotor speed, you increase cooling time, and your expensive mixer sits idle longer than it should.
This is where our Premium PVI changes the game.
By introducing our high-purity PVI, you are essentially buying “Thermal Insurance.”
- Run Hotter: You can safely increase dump temperatures by 10°C – 20°C.
- Run Faster: Higher temperatures mean lower viscosity and faster mixing cycles.
- The Result: A potential 10-15% increase in mixer throughput without spending a dime on new equipment.
Why “Good Enough” is Costing You Money
You might think, “I already use PVI. It’s a commodity.”
This is a dangerous misconception. In high-speed tire production, Dispersion is King. A cheap, coarse PVI powder does not disperse instantly. It leaves “hot spots” in the batch where protection is missing, and “dead spots” where cure is retarded too much.
We engineered our PVI to be the “Invisible Champion” of your formula:
1. Micro-Dispersion Technology
We don’t just sell chemicals; we sell consistency. Our PVI is processed to a specific particle size distribution that guarantees rapid melting and uniform distribution within the rubber matrix—even in short mixing cycles.
2. The Purity Advantage (Specs that Matter)
Impurities in additives act like grit in an engine. Our specs are tighter than the market standard to ensure your extruders run smooth:
- Ash Content: ≤ 0.05% (Market Avg: 0.30%) —> Benefit: Zero screen-pack clogging.
- Purity: ≥ 98.0% —> Benefit: Precise, predictable scorch delay.
- Oil-Treated Option: We offer oil-coated PVI to suppress dust, keeping your factory clean and ensuring accurate weighing.
Sector Spotlight: High-Performance Tires
In the production of Radial Tires, consistency is non-negotiable.
- For the Tread: Our PVI allows for the aggressive mixing of silica-silane compounds without premature crosslinking.
- For the Wire Coat: It ensures the compound remains flowable long enough to penetrate the steel cords perfectly, critical for belt durability.
- For the Bottom Line: It reduces scrap rates. Imagine saving just 0.5% of your total annual compound from scorching. That saving alone covers the cost of our PVI multiple times over.
A Challenge to Your Current Formula
We believe that PVI should be an asset, not just an additive.
If you are currently dealing with:
- Inconsistent Mooney Scorch times?
- “Rough” surfaces on extruded profiles?
- Limitations on mixer speed due to heat risks?
Then your current PVI might be the bottleneck.
