Silicone vulcanizator for food grade silicone rubber products FDA level
C-100AB,two component platinum addition type cross linking agent which is added in the raw silicones for the cross linking of food and medical grade silicone rubber items ,The vulcanized products can pass the FDA test, ,it features with non-toxic, odourless, high grade of transparency, well anti-yellowing and other properties.
Food Grade and Medical Grade,No secondary curing
C-100A: transparent paste, containing platinum and organic silicon polymer
C-100B: transparent organic silicon polymer, containing crosslinking agent and inhibitor
Tensile Strength(Mpa) :10~12
ElongationatBreak(%):500~540Compression Set %(100℃/22h):<5
The raw material is easy poisoning once contact with nitrogen, phosphorus, sulfur and heavy metalmaterials.
C-100A and C-100B can not be added at the same time. First add C-100B into raw silicone and mixing evenly, then add C-100A into raw silicone. The addition order isimportant.
The temperature of mixing machine which used for mixing silicone with platinum curing agent can not be higher than 45℃. Please add this agent after beingcold.
The mixed raw materials should be used up within twodays
.Please choose the suitable raw materials for hot air vulcanization,unmatched raw materialwill cause bubbles in the process.
Type one: Extrusion Or Injection Moulding
