1. Raw Materials & Composition
- Primary Source: 100% selected Tread Rubber Powder from waste truck tires. We use high-content rubber from the tire tread to ensure the 10MPa tensile strength.
- Additives: Eco-friendly activating agents and naphthenic oil (softener) to maintain excellent processing safety.
- Purity: Rigorously screened to ensure it is free from metal, textile fibers, and moisture.
2. Production Process: ZY-1000 CNC Continuous Line
Our KH-10 is manufactured using our patented Boiler-free Mechanochemical Process:
- CNC Precision Batching: Automated weighing of tread powder and activators for batch-to-batch consistency.
- Continuous Devulcanization: Under atmospheric pressure, high-precision rotors break the sulfur bonds efficiently while preserving the molecular weight of the rubber.
- Low-Temperature Processing: Unlike traditional autoclaves, our process avoids over-heating, which prevents the rubber from becoming “sticky” or “burnt.”
- 100-Mesh Fine Filtration: Passed through a high-density dual filter to ensure the KH-10 sheets have a flawless, smooth surface.
- Automated Sheeting: CNC cutting and cooling for uniform thickness (standard 10-12mm sheets).

4. Primary Applications
KH-10 is the preferred choice for manufacturers who need a balance between cost and performance:
- Solid Tires & Castors: Provides the necessary load-bearing strength and abrasion resistance.
- Rubber Soles: High-grade shoe outsoles and industrial work boot bases.
- Gaskets & Seals: Excellent compression set for industrial sealing components.
- Hose Pipes: Inner lining for low-pressure industrial hoses.
- Engine Mounts: Anti-vibration pads for machinery.
5. Cost & ROI Analysis
- Substitution Ratio: KH-10 can replace up to 25%-35% of Natural Rubber in many formulas without significant loss of performance.
- Factory Efficiency: Stable Mooney viscosity means fewer adjustments to your mixing machines, saving labor and time.
- Energy Saving: Our production line consumes 30% less electricity than traditional “Pot” methods, allowing us to offer more competitive wholesale prices.
