easy-releasing ability, RTV-2 silicone, as the soft mould material,

Detailed

RTV-2 Liquid Silicone Rubber (Silicone Molding) 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.

Notes:

(1) Mixing ratio, Pot life and Demould time in above table is measured under the conditions of room temperature of 25 °C, relative humidity of 65 to 70%.The dates is only for reference.Mixing ratio should be modified according to various temperatures.

(2) When the temperature and the humidity is higher, the curing speed will be accelerated with the same amount of curing agent. the more the amount of curing agent added, within a certain range, the curing speed will accelerated;the affects by temperature is larger than by humidity; and the volume shrinkage of vulcanized rubber is also correspondingly larger.

(3) Standard dates above are tested at the following standards:

Viscosity is tested by NDJ-7 rotary viscometer relevant provisions; hardness, tensile strength, tear strength, elongation are tested based on GB531, GB528, GB529 ,GB52 respectively.
