产品详细信息
未经处理的PBT颗粒
PBT颗粒的特征：
1，机械性能：高强度、耐疲劳、尺寸稳定性、蠕变也很小（高温条件很少改变）
2，热老化：UL温度指数提高120~140℃（户外长期老化也很好）
3，耐溶剂性：无应力开裂
水稳定性：PBT易被水分解（高温、高湿环境需谨慎）
电气性能：
（1）绝缘性能：优异（潮湿、高温能保持电气稳定性，是制造电子电气零件的理想材料）
（2）介电系数：3.0-3.2
耐电弧性：120s成型加工性：普通设备注塑或挤压。由于结晶速度快，流动性好，模具温度也低于其他工程塑料的要求。在薄壁零件的加工过程中，只需几秒钟，大型零件的加工时间仅为40-60秒

Product Details
Virgin PBT Pellets
Features Of PBT Pellets:
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;
4, water stability: PBT easy to break down with water (high temperature, high humidity environment need to be cautious);
5, electrical performance:
(1) Insulation properties: Excellent (humid, high temperature can maintain electrical stability, is the ideal material for the manufacture of electronic and electrical parts)
(2) dielectric coefficient: 3.0-3.2;
(3) Arc resistance: 120s
6 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.
