橡塑产品填料基本要求
橡塑制品用高岭土产品性能对照表
一,橡塑制品使用无机粉体填料的基本性质在橡塑加工及使用过程中保持化学性质和物理形态的稳定;改善树脂的某些性能:提高刚性、提高耐热性、提高电绝缘性;改善耐候性、增加尺寸稳定性;着色力、导热性、导电性、阻燃性;
二,对无机粉体填料的基本要求
1)化学性质稳定,相对纯度高,杂质含量低;
2)颜色尽量为白色或浅色,不含铁等易加热变黄的杂质;
3)不对塑料制品的理化性能指标产生严重损害;
4)容易分散和混合,粒度适当;
5)吸油值相对较低,对加工性无大影响;
6)有合适的微观晶型结构;
7)有较低的莫氏硬度;
三,橡塑应用要求填料的特性粒径及粒径分布。晶型结构。吸油性。分散性。粘度特性。刚性与硬度。电气性能。
