Product Details
 简称PBT

 俗称 聚酯
学名 聚对苯二甲酸丁二醇酯
英文名 polybutylene terephthalate

   本色PBT是一种从不透明到半透明的白色材料,有较高表面硬度而且有较高的表面光泽;薄膜呈透明状;
燃烧特征: 慢燃,离火后能继续燃烧,火焰上端呈金黄色,下端成兰色,燃烧时发生熔融滴落,有浓烟和飞恢;并发出强烈的农药的刺激性气味。

  PBT优点:PBT最大的优点是:在较高的温度和较低的温度下,都具有优良的冲击性能,PBT磨耗小,它的磨耗小于POM
PBT
刚性大,虽然收缩率大,但尺寸稳定。PBT介电性能好,无应力开裂。PBT除了强的无机酸和无机碱外,其它溶剂对它无作用。

   PBT缺点:PBT最大的缺点是不耐高温,热稳定性差,PBT不耐疲劳,不能自润滑。PBT耐酸性差,不耐酸的侵蚀。PBT用途 生产齿轮,轴承,耐药品的工具外盖,要求耐冲击的防护面罩,水泵外盖。
制品的强度和外观,因此,需要烘干,在100℃烘干2-3小时即可;温度不可太高,否则无染色制品会变色。
   PBT
注塑性能: :PBT是结晶性塑料,有明显的熔点,224℃时熔化,320℃时就分解;一般加工温度为230℃--260℃;它的加工范围很窄;但它的粘度受温度影响很大;它吸水,在注塑时少量的水就能引起大量分解,降低
PBT
(聚对苯二甲酸丁二醇酯)
特点:极高尺寸安定性,高的热稳定性,优异的滑动能力,机械加工性佳,
低膨胀率,电气绝缘优异。高机械强度/硬度及刚性,耐酸,易焊合及
胶合,耐磨。
缺点: 电介性不佳,会水解,对紫外线敏感,长期户外使用易
脆,不耐强酸/碱性溶剂及氧化剂,不耐凹口冲击。
板材: 厚度(6~50㎜)*宽620㎜*长1200㎜
棒材: ¢6~ ¢200㎜*1000㎜
