Description
The PVC/CR blend combines the oil resistance, weather resistance, and flame retardancy of CR with the abrasion resistance, acid resistance, and low cost of PVC. It features a smooth surface and is suitable for mining and industrial environments requiring anti-static and flame-retardant properties.
Applications
Flame-retardant conveyor belts for mining
Oil- and weather-resistant hose covers
Wire and cable sheathing
Industrial rubber rollers

FAQ
Q: Do you sell finished products or raw materials?
A: We only supply rubber compounds, not finished products. You can choose hardness, color, and formulation based on your product needs. We mix to order and deliver.
Q: What rubber types can you handle?
A: Common types include NR, SBR, BR, NBR, EPDM, CR, silicone rubber, fluororubber, etc., subject to actual capability.
Q: Are hardness and formulation linked?
A: No. The same hardness can be achieved with different formulations. The difference lies in tensile strength, tear resistance, compression set, oil resistance, aging resistance, etc. Tell us your application and we’ll recommend the right system.
Q: Can you compound to the customer’s formula?
A: Yes. We support toll processing with customer-supplied materials or mixing to a customer-specified formula. We can also recommend a formula based on performance requirements.
Q: How do you ensure batch-to-batch consistency?
A: Through raw material batch control, fixed mixing process parameters, and sampling tests (hardness, specific gravity, Mooney viscosity, etc.).
