Silicone Rubber For Molds

Various properties about excellent liquidity, good work-ability, good tensile?force, with no deformation, heat resistant, acid and alkali resistant. Can be used repetitively. 2.Specification Silica gel is mixed with curing agent, the appearance of molding silica gel is liquid, A substitutes silica gel, B substitutes curing agent. For example, 100g A add 2g curing agent, but it needs to note, A and B must be mixed averagely, if not, the molding will not cure completely, and heterogeneous silica gel can affect its life time and result in that the molding will be completely scrapped. Packaging by airtight polyethylene drum.

The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise. 3.
