Liquid Silicone Platinum Silicone Rubber For Smooth Pouring On Mold Making
High Quality Liquid Silicone Rubber Material for Diving Products
It has the characteristics of high transparency, high strength, good resilience, small deformation value, yellowing resistance and aging resistance;
Meets US FDA CFR21.Part.177.2600 and European EN14350-2, Section 4.9 Volatile Compound Test Standards and Ruropean ROHS and TEACH Standards;
The pot-life of the mixture of the two components(closed vesssel) at 20 ℃ is 5 days. Increased temperatures reduce the pot-life.
Suitable for producing high transparent & high precision silicone rubber mold.

1. What's silicone products you are making?
--liquid silicone rubber, silicone rubber, silicone oil; Platinum agent: -- According to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.
2. Do you offer free sample to client?
--Yes, we can provide the sample for test.
3. How about the quality control in your factory?
--We have professional QC team. --Each batch of silicone rubber must be tested by our safe quality examination system.
4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.
5. How to get good silicone mould to use longer time?
--The best way is:
1, Please choose the right liquid silicone according to your products.
2, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use.
3, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished.
6. Why silicone rubber add curing agent after mixing a lot of bubbles?
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
