1. Raw Materials & Composition
- High-Grade Feedstock: 100% selected Radial Tire Tread Powder. We exclusively use tire tread rubber from heavy-duty trucks to ensure high natural rubber content and superior tensile strength.
- Refined Additives: Specialized environment-friendly activating agents and high-flash-point aromatic oils to ensure excellent aging resistance.
- Purity Control: Triple-stage magnetic separation and air-suction de-dusting to guarantee zero impurities.
2. Production Process: ZY-1000 CNC Continuous Line
Our KH-12 is produced using our signature Boiler-free Mechanochemical Process:
- CNC Automated Batching: Computer-controlled ratio of tread powder and activators ensures batch-to-batch consistency—crucial for high-precision manufacturing.
- Intensive Devulcanization: The raw material undergoes high-shear mixing in a continuous reactor at atmospheric pressure, restoring elasticity without degrading the polymer chains.
- Heat Management: Our process uses friction-generated heat, eliminating the need for steam boilers. This results in a “greener” product with no burnt smell.
- Dual 100-Mesh Filtration: The material is refined through ultra-fine 100-mesh screens to achieve a Super Fine surface finish.
- Precision Sheeting: Sheets are extruded at a controlled thickness (10mm-12mm) for easy handling and mixing.

4. Primary Applications
KH-12 is specifically designed for applications requiring high dynamic fatigue resistance:
- Conveyor Belt Core: Provides excellent adhesion and tensile strength for the internal structure of industrial belts.
- Industrial Hoses: Used in the inner and outer layers of agricultural and industrial water/oil hoses.
- Anti-Vibration Mounts: Ideal for heavy machinery pads and automotive engine mounts.
- High-Load Castors: For industrial wheels that require high abrasion resistance.
- Agricultural Tires: Suitable for sidewalls and treads of low-speed agricultural vehicles.
5. Cost & ROI Analysis
- Significant NR Substitution: KH-12 can effectively replace 35%-45% of Natural Rubber in many industrial formulas, offering a massive cost advantage.
- Energy Efficiency: Produced by our CNC line which consumes 30% less power than traditional autoclave methods, allowing for a more competitive price per ton.
- Quality Stability: High tensile strength means you can use more reclaimed rubber and less virgin polymer, significantly lowering your overall compound cost (COGS).
