Comfortable Medical Grade Silicone Rubber UV Light Resistance Fit
Breathing Nasal Mask
RH6250-40YH is medical grade liquid silicone rubber for injection
molding processes. At higher temperatures the safety operation time shortened. LSR RH6250-40YH liquid silicone rubber is platinum cured(vulcanized) materials which are mixed in a 1:1 ratio
This product is suitable for a two-component injection molding
process. LSR is platinum cured(vulcanized) materials which are mixed in a
1:1 ratio by weight.

Q: Why is the tear strength of the silicone mold weak?
A: There are three reasons:
- In order to reduce the viscosity of silicone rubber and pursue a
good quality, you may add a lot of silicone oil into the silicon
rubber when making molds. In fact, it might have just the opposite
effect. The tension and the tear strength will be reduced badly
with the addition of silicon oil. And the silicon molds will be in
a weak and flimsy manner.
- You may add too much catalyst into the silicone rubber, we suggest
customers add catalyst no more than 5%, 2%will be perfect.
- You may use the silicone mold too early after it finished. We
suggest the customer begin using the molds after 24 hours. What’s
more, it will be better if you can make an outer mold to protect
the silicone mold.
This product cannot be contacted with compounds containing N, P, S
to avoid affecting the catalytic effect of platinum.
