TPV Granules, or Thermoplastic Vulcanizate, represent one of the most advanced materials within the Thermoplastic Elastomer (TPE) family. As an engineered material, they uniquely combine the benefits of traditional vulcanized rubbers with those of thermoplastics. Through the intelligent combination of a plastic phase (typically polypropylene) and a fully cross-linked rubber phase (typically EPDM), TPV offers an economical, durable, and easily processable solution for modern industries.
What is TPV and How is it Made?
TPV is the result of a complex manufacturing process called Dynamic Vulcanization. During this process, rubber particles (such as EPDM) are fully cross-linked (vulcanized) within a molten thermoplastic matrix (such as PP). The outcome is a material that retains the excellent elasticity and recovery properties of rubber, yet can be melted, molded, and recycled like a conventional plastic.
Key Properties and Advantages of TPV Granules
- Excellent Flexibility and Elasticity: Capable of stretching 300–600% without tearing.
- High Heat Resistance: Can withstand continuous operating temperatures from 120°C to 135°C.
- Exceptional Compression Set Resistance: Effectively recovers its original shape even after prolonged compression at high temperatures.
- Superior Environmental Durability: Excellent resistance to UV radiation, ozone, weathering, water, and moisture.
- Good Chemical Resistance: Resistant to oils, greases, detergents, and many diluted chemicals.
- Fast and Easy Processability: Can be shaped using injection molding, extrusion, and multi-component molding without a separate vulcanization step, significantly reducing production time and cost.
- Recyclability: Production waste and end-of-life parts can be recycled and reused.
- Lightweight with High Dimensional Accuracy: Ideal for complex designs requiring tight tolerances.
Why Choose TPV?
TPV Granules are the optimal choice when you need a material with the flexibility and durability of rubber, but the production speed and economics of plastic. If your goals include reducing total cost of ownership (TCO), increasing production line speed, designing complex high-performance parts, or moving towards greener, recyclable production, TPV offers a forward-thinking and cost-effective solution.
