FAQ
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:
- Please choose the right liquid silicone according to your products.
- Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use.
- 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.
