1. Raw Materials & Composition
- Primary Source: Selected Whole Tyre Rubber Powder (derived from recycled truck and passenger car tires).
- Processing Agents: High-quality environment-friendly softening oils and chemical activators (devulcanizing agents).
- Purity: 100% free from metal, fiber, and moisture, ensured by our multi-stage magnetic and air separation system.
2. Production Process (The Kangheng Advantage)
Our 8MPa rubber is produced using the ZY-1000 CNC Continuous Mechanochemical Process, which is vastly superior to traditional autoclave methods.
- Step 1: Automated Batching: Precision CNC weighing of rubber powder and additives.
- Step 2: Continuous Devulcanization: Under atmospheric pressure, high-shear rotors break the sulfur-crosslinks (devulcanization) without damaging the rubber polymer chains.
- Step 3: Self-Heating (Boiler-Free): The process uses mechanical friction to generate heat. No steam boiler is required, making it safer and 30% more energy-efficient.
- Step 4: Dual Fine Filtration: The material passes through a 100-mesh filter to ensure a smooth, defect-free surface for your final products.
- Step 5: Automatic Cooling & Sheeting: Precision thickness control and automated cutting for uniform sheets.

4. Primary Applications
The KH-08 (8MPa) grade is highly versatile and cost-effective for:
- Automotive Flaps & Liners: Ideal for truck tyre flaps and rim liners.
- Industrial Rubber Sheets: Waterproofing membranes and anti-vibration mats.
- Construction: Rubber floor tiles, soundproofing layers, and roofing materials.
- Footwear: Secondary outsoles for work boots and low-cost sandals.
- Traffic Safety: Speed bumps, road cones, and corner guards.
5. Cost Analysis & ROI (Return on Investment)
- Raw Material Savings: KH-08 typically costs 30% – 40% of the price of Natural Rubber (SMR/RSS).
- Energy Efficiency: Our production line consumes approximately 650 kWh per ton, significantly lower than traditional “Pot” methods.
- Maintenance: With no high-pressure boilers, you save on annual inspection fees, specialized labor, and safety compliance costs.
