Classification of Silicone Rubber Silicone rubber is a kind of network structure elastomer crosslinked by linear polysiloxane with high molecular weight divided into solid silicone rubber and liquid silicone rubber. Solid Silicone Rubber Composition: High molecular weight silicone polymer + filler Shape: Solid  Usage: Add sulfurizing agents (such as platinum catalysts) for molding or extrusion. Liquid Silicone Rubber Composition: Polysiloxane + filler    Shape: Liquid or paste Usage: A / b two-component mixed molding Note: Self-adhesive liquid adhesive belongs to this kind of particular branch. Manufacturing Process of Silicone Rubber Solid Molding Solid molding is mainly suitable for solid glue and [...]

The advantages of selective self-adhesive liquid silicone rubber are given below: Increase production capacityAccording to the following comparison, we can see the advantages of selective self-adhesive liquid silicone rubber in improving liquid silicone rubber molding production capacity: Primer + mixed-rubber manual + molding: the production capacity is about 30%. Primer + mixed-rubber semi-automatic + molding: the production capacity of about 60%. Primer + ordinary liquid glue + injection: the production capacity is about 80%. Self-adhesive liquid adhesive + injection: the production capacity is about 90%. Reduce energy consumption According to the following comparison, we can see the advantages of selective self-adhesive liquid [...]

C8H19NSi2 is a colorless transparent liquid non-toxic, soluble in ethyl acetate, toluene, cyclohexane, and organic solvents which use in liquid silicone rubber curing. Reference Data for Divinyltetramethyldisilazane（C8H19NSi2）in Liquid Silicone Rubber Curing: CAS No.: 7691-02-3, C8H19NSi2 content (%): ≥ 96.0 C8H18OSi2 content (%): ≤ 4.0 Note: C8H19NSi2 in liquid silicone rubber curing is used to treat fumed silica (2% - 5% of the usual recommended dosage), and the treated silica becomes hydrophobic from hydrophilic and has a better affinity with raw rubber. Nevertheless, it can be used as a ceramic surface treatment agent. It can be used as a synthetic intermediate of [...]

Platinum catalyst is a kind of catalyst with high activity and high catalytic efficiency in silicone rubber curing. Platinum catalyst can efficiently catalyze the addition reaction of Si-Vi and Si-H without side reaction. Besides, platinum catalyst also has the advantages of good stability and strong anti-toxic, which can avoid the formation of black substances in the process of storage or use, and reduce the influence of nitrogen and sulfur-containing substances. In addition to the above advantages, platinum catalyst material also has the advantages of good selectivity, less by-product, little influence on the transparency of the compound, high transparency products and eco-friendly chemical feature. Platinum catalyst [...]
