1. Raw Materials & Composition
- Premium Feedstock: 100% top-tier Radial Truck Tire Tread Powder. We select only high-tensile tread rubber with high natural rubber content to ensure the 14MPa threshold.
- Elite Additives: Advanced environmentally friendly activating agents and low-volatility processing oils to guarantee superior aging resistance and heat stability.
- Purity Assurance: Multi-stage centrifugal separation and high-intensity magnetic filtration to ensure a 100% impurity-free compound.
2. Production Process: ZY-1000 CNC Continuous Line
Our KH-14 is produced using our signature Boiler-free Mechanochemical Process:
- CNC Precision Feeding: Automated, sensor-based batching of tread powder and activators ensures identical quality in every ton—critical for high-end industrial clients.
- Dynamic Devulcanization: Continuous high-shear mixing at atmospheric pressure breaks sulfur bonds while preserving the long-chain polymer structure, resulting in higher elongation (≥480%).
- Low-Heat Processing: By converting mechanical energy into controlled friction heat, we avoid the “thermal degradation” common in old-fashioned steam autoclaves.
- Super-Fine 100-Mesh Filtration: The material is refined through ultra-dense 100-mesh screens to achieve a Super Fine surface finish, essential for precision molding.
- Cooling & Sheeting: Automated cooling systems ensure the rubber sheets (10-12mm) retain their physical properties during storage.

4. Primary Applications
KH-14 is designed for heavy-duty applications that demand high dynamic strength:
- Premium Conveyor Belting: Ideal for the cover and core of high-tension belts used in mining and heavy industry.
- Heavy-Duty Solid Tires: Provides excellent load-bearing capacity and cut resistance for forklift and industrial vehicle tires.
- High-Pressure Hoses: Used in the reinforcement layers of hydraulic and agricultural hoses.
- Engine Mounts & Bushes: Superior anti-vibration properties for automotive and industrial machinery.
- High-Grade Footwear: Outsoles for premium safety boots and technical footwear.
5. Cost & ROI Analysis
- High NR Replacement: KH-14 can replace 40%-55% of Natural Rubber in premium formulas, offering massive savings on raw material costs (COGS).
- Enhanced Durability: The high tensile strength (14MPa) ensures that the final product has a longer service life, reducing warranty claims for your clients.
- Operational Savings: Our CNC line consumes 30% less energy, allowing us to provide KH-14 at a price that maximizes your factory’s profit margin compared to virgin polymers.
