1. Raw Materials & Composition
- Elite Feedstock: 100% Selected Radial Truck Tire Tread Rubber (Premium Quality). We only use tread powder from top-tier brand truck tires to ensure maximum natural rubber content and molecular integrity.
- High-Performance Activators: Proprietary, environment-friendly devulcanizing agents designed for high-tensile retention.
- Purity Control: Zero-tolerance for impurities. Multi-pass magnetic and air-filtration ensures the raw material is perfectly clean.
2. Production Process: ZY-1000 CNC Continuous Line
Our KH-16 is the masterpiece of our Boiler-free Mechanochemical Process:
- CNC Intelligent Batching: Precise control of the activator-to-powder ratio to achieve the 16.0 MPa threshold consistently.
- Ultra-High Shear Devulcanization: Continuous mixing at atmospheric pressure using high-precision rotors. This process “unlocks” the sulfur bonds without “tearing” the rubber polymer chains, preserving the highest possible elongation (≥560%).
- No Thermal Degradation: Because we use mechanical friction rather than high-pressure steam (Boiler-free), the rubber maintains its “living” elasticity and won’t become brittle.
- 100-Mesh Dual Filtration: The material is refined through ultra-dense 100-mesh screens to achieve a Super Fine surface finish—critical for high-speed conveyor belts.
- Precision Cooling & Sheeting: Automated cooling to prevent “scorch” and maintain the shelf life of the rubber.

4. Primary Applications
KH-16 is the ultimate solution for high-dynamic stress environments:
- Premium Conveyor Belts (Grade M-24 / N-17): Perfect for the outer cover of heavy-duty belts used in mining and steel plants.
- High-Tensile Industrial Parts: Buffer blocks, high-pressure gaskets, and abrasion-resistant liners.
- Performance Solid Tires: For heavy-duty forklifts and port machinery requiring extreme cut resistance.
- Natural Rubber Replacement: Used in any high-end rubber formula to replace up to 50%-60% of Natural Rubber while maintaining performance.
- Shoe Soles: High-end safety boots and technical footwear outsoles.
5. Cost & ROI Analysis
- Maximum Cost Savings: Despite being our most expensive grade, KH-16 provides the highest ROI because it allows you to significantly reduce the dosage of virgin Natural Rubber (SMR/RSS).
- Energy Efficiency: Our CNC line consumes 30% less power than traditional autoclave methods, keeping our wholesale price competitive.
- Low Rejection Rate: Stable Mooney viscosity and 100-mesh fineness mean fewer defects in your final products, saving you money on scrap and rework.
