Virgin Pbt granules pbt plastic raw material gf30
1. mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (high temperature conditions rarely change);
2. heat aging: enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term aging is also very good);
3. solvent resistance: no stress cracking;
d, water stability: PBT is not easy to break down with water;
4.electrical performance:
-- Insulation: Excellent (humid, high temperature can also maintain electrical stability, is the ideal material for the manufacture of electronic and electrical parts);
--dielectric coefficient: 3.0-3.2;
-- arc resistance: 120s
5. molding processability: ordinary equipment injection molding or extrusion.
As the crystallization speed, good fluidity, mold temperature is also lower than other engineering plastics requirements. In the processing of thin-walled parts, only a few seconds, only 40-60s for large parts can be.
