Outstanding Resistance To Yellow Rapid Vulcanization Liquid Silicone Rubber for Scuba Mask
RUI-HE 6250-25T® is a kind of two-component liquid silicone rubber for injection molding processes, consisted of part A and part B. It can be used to produce electronics keys supplies with high rebound and good resistance to yellow. All LSR are platinum cured (vulcanized) materials which are mixed in a 1 : 1 ratio by weight.

These figures are for reference only, please contact us for details.
Mixing ratio of components A : B = 1 : 1.
Vulcanization: 150 °C / 5 min
Because of the outstanding properties 6250-25T® liquid silicone rubber is particularly suitable for keys supplies, such as computer keyboard.
Rui-He 6250-25T® Liquid silicone rubber obtained the following test certificate: RoHS, FDA.21.177, REACH, PAHS, ISO9001:2016, etc.
Packaging & Storage
Available in 20kg pails or 200kg drums.
Store in a cool, dry place out of direct sunlight, use it within 12 months from the day of manufacture.
This product cannot be contacted with compounds containing N, P, S to avoid affecting the catalytic effect of platinum.
Q: How many kgs of silicone I need to make a mold, like 1m*1m?
A: First, you change the "m" to "cm". Then the V(volume)=100cm(length)*100cm(width)*1.5cm(height or thickness) =15000cm3
→ the density of the liquid silicone is 1.1g/cm3→ the quantity= 15000cm3* 1.1g/cm3=16500g(16.5kg)
Q: How can I know the thickness of the silicone mold?
A: For the pouring way, if you do not have a plaster have a base to keep its shape (like square), then we usually suggest that 2-3cm is enough. If yes, then 1-1.5 cm is enough.
Q: Why is there not enough 25kgs silicone in the drum?
A: V=m/p. because the different of the silicone viscosity, so there will be a little difference. When the viscosity is lower, there will be 26kgs or more. In contrast, there will be 24kgs or little.
