Application of silicone rubber for mold making:
silicone rubber for mold making is mainly applicable to make the silicone mould for cultural relic duplication,architectural decoration,resin crafts, lighting ornaments, candles, statues, model design, product exploitation, etc.
Features of silicone rubber for mold making:
a. low viscosity, exceptional fluidity and easy operation
b. resistance to deformation, high-temperature
c. acid, alkali and ageing-resistance
d. low shrinkage
e. good tensile strength
f. high reproduction times
Datasheet of silicone rubber for mold making:

Instruction of silicone rubber for mold making:
Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 2-3 hours.
1. Adding curing agent 1%, the silicone rubber can still be operated within 2.5 hours and can be Demoulded after 6-8 hours.
2. Adding curing agent 2%, the silicone rubber can still be operated within 50 minutes to 1 hour and can Be demoulded after 2-3 hours.
3. Adding curing agent 3%, the silicone rubber can still be operated within 28 - 30 minutes and can bedemoulded after 1.5-2 hours.
4. Adding curing agent 4%, the silicone rubber can still be operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.
FAQ of silicone rubber for mold making :
Why the silicone rubber mold just can be reproduced for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.
(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
