FAQ
Q: How to get good silicone mould to use longer time?
A: --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.
Q: Silicone seems to be more expensive than other rubber, why is
this?
A: Silicone is more expensive than most rubber types because it is
a speciality high performance polymer with outstanding qualities.
It is made in relatively low quantities and requires expensive and
complicated primary manufacturing facilities.
