Frequently Asked Questions
What exactly is PC polycarbonate granule and how does it stand against other polymer granules?
PC polycarbonate granule is a thermoplastic polymer that comes in the form of pellets and is widely used for its transparency, impact resistance, and good thermal performance. The finest feature of polycarbonate is that it is less subjected to breakage and also more stable dimensional-wise during thermal stress than other polymers which make it the most preferred material at demanding places.
Key Specifications
- Granule size: Usually 3 mm nominal which may affect the consistency of feeding during extrusion and injection molding
