RTV liquid silicone rubbber for making mold

RTV liquid silicone rubbber for making mold is a common silicone rubber that can get cured at the room temperature.The raw material of the silicone is Polydimethylsiloxane (-(-O-Si(CH3)2-)-),which is at the both ends of –OH.The chemical formula is as below:

CH₃ CH₃CH₃

Ho—si—o Si o Si OH

CH₃ CH₃ n CH₃

Different models of RTV liquid silicone rubbber for making mold will be produced by adding different kinds and amounts of extender and other additives into the unvulcanized rubber. It is composed as two parts, one is the unvulcanized silicone, and the other is the curing agent, cross-linker and the other curing agent.

RTV liquid silicone rubbber for making mold Performance:

RTV liquid silicone rubbber for making mold is with the good features of excellent insulation resistance, voltaic arc resistance, high corona resistance ,water-tolerant, ozone proof, aging resistance, high and low temperature stability, and it could be used under the temperature of -60~200°C.

After adding the curing agent and cross-linker into the unvulcanized silicone, pls go for the vacuum pumping process if necessary.Then the mixture will be cured into the elstomer. And the pot life and the curing time can be changed by controling the formula and the volume of the catalyst

RTV liquid silicone rubbber for making mold Main applications:

The mixing ratio of the two parts of RTV-2 is adjustable. One kind of mixing ratio can get many kinds of cured product with different specification and performance. What’s more, by adding special additives, it can get deeper layer 'curing and increase the corrosion resistance.Thus it is used widely for insulating, sealing, bonding, filleting, dampproofing, shockproofing and as the raw material for the silicone roller, which could be applyied to the field of electronicals, autocar, aviation industry, machanical construction, textile industry, chemical industry, printing and light industry, hygienism industry and so on. Besides, because of the easy-releasing ability, RTV-2 silicone, as the soft mould material, also could be mainly applied for making molds for replicating stationaries, cafts, toys, artificial leather, electronicals, instruments, machine parts and so on.

Different products with different performance for different applications by different technics could be provided by our company.
