Application
1、在丙烯酸酯椽胶的 HDC 硫化配方中用作脱模剂般用量是 0,5 份。若增加用量 , 可提高焦烧安
全性略微降低硫化潓率和硫化程度。压缩永久变形和拉伸强度会略受影响 , 但二次硫化之后便会
恢复。
Used as internal release agent in the HDC curing system of ethylene acrylate copolymer,and the normal
dosage is 0.5phr.Increasing 18D can result in improbement in scorch safety,slight reduction in cure rate
and cure state.Compression set and tensile strength will be negatively influenced but these properties are
normally recovered after post-cure.
2、若用 18D 来提高焦烧安全性 , 建议尝试增加 0.25 份的用量。
If 18D is used as retarder to improve scorch safety,the recommendation is to add 0.25phr increments.
3、使用后可使硫化胶的抗热老化性能更优。
It can bring vulcanizate with better properties after heat aging.
