RTV 2 silicone rubber for mould making features
RTV 2 silicone rubber for mould making is white or red flowing liquid with general hardness of 22-50A°after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength ,tear strength and elongation.
Description of RTV 2 silicone rubber for mould making:
silicone rubber for resin craft mainly used for shoe molds, sand casting, sole sampling, plaster models, simple products, products with non-complex patterns, as well as product models with stable size and non-deformation.
RTV 2 silicone rubber for mould making data sheet:
Model | Color | Mixing ratio (%) | Pot life (mins) | Demould time ( hrs) | Hardness ( A0 ) | Tensile-strength (kgf/cm2) | Tear-strength (kgf/cm) | Viscosity (cps) | Shrinkage rate (%) | Elongation (%) |
638# | white | 100 : 3 | 30 | 5-10 | 38 | ≥ 38 | ≥ 28 | 34000-36000 | ≤0.3% | 380% |
630# | white | 100 : 3 | 30 | 5-10 | 30 | ≥ 47 | ≥ 35 | 28000 | ≤0.3% | 430% |
RTV 2 silicone rubber for mould making advantages:
* Reusable
* Molds can be used over and over again.
* Does not shrink
* Has good abrasion resistance.
* Comes in a wide range of hardnesses and therefore gives long mold life.
* Can be poured, brushed or sprayed on to the original model.
* Is the most economical overall (compared to other mold rubbers).

Frequently asked questions of RTV 2 silicone rubber for mould making
Why does the silicone rubber mold have few molding times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
