Packaging:Barrel or drum:Usage:
Used in conjunction with peroxide vulcanization as a bridge agent, it can improve bridge density, increase tensile strength, reduce permanent deformation under compression, and shorten vulcanization time.,:It has a plasticizing effect during mixing and a hardening effect after vulcanization, can be used as a hardener for high hardness products, approximately every increase of
1 PHR TMPTMA , can increase hardness by one degree.200kg/Improves crosslinking efficiency and reduces peroxide usage.25kg/Since this product is a colorless transparent liquid, it is also suitable for the transparent product industry.
Recommended Dosage: , when used as a co-crosslinking agent in general rubber, it is recommended to add
12-4 PHR
2, in EVA foamed products, it is recommended to add 0.5-1.0 PHR, in high hardness products, it is recommended to add10-20 PHR
3, in EVA foamed products, it is recommended to add 提高交联效率,降低过氧化物使用量。
4, in EVA foamed products, it is recommended to add 因本品为无色透明液体,也可适用于透明制品行业。
