PP Lumps
PBT (Polybutylene Terephthalate) grinding is a mechanical size-reduction process used to convert PBT plastic materials into powder, granules, or regrind particles. PBT is a semi-crystalline engineering thermoplastic belonging to the polyester family, widely known for its strength, dimensional stability, chemical resistance, and electrical insulation properties.
Grinding PBT is an important step in recycling, compounding, and manufacturing, enabling efficient reuse of material and cost reduction.
Key Properties of PBT
- High mechanical strength
- Excellent dimensional stability
- Good heat resistance
- Low moisture absorption
- Excellent electrical insulation
- Chemical and solvent resistance
