Fast Curing High Transparency And High Adhesion Liquid Silicone
Rubber For Printing
Description
RUI-HE 9240-25M® 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 the fabric surpace of the silk screen and
silicone rubber bracelet with high transparency,fast curing and
high adhesion. All LSR are platinum cured (vulcanized) materials
which are mixed in a 10 : 1 ratio by weight.
Features
1.High transparency, high strength, good resilience, small
deformation value, yellowing resistance and aging resistance;
2.Comply with US FDA CFR 21.Part.177.2600 and European EN14350-2,
Section 4.9 Volatile Compound Test Standards and European ROHS and
REACH Standards;
3.In the environment of 20 °C, the safe operation time is 3 days
after the A/B components are mixed and sealed, and the safe
operation time is shortened when the temperature rises.
Applications
Because of the outstanding properties 9140-25M® liquid silicone
rubber is particularly suitable for textile silk screen printing and webbing products.

storage and use may cause poisoning of the platinum catalyst and
affect vulcanization.
Tips
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.
Q: Why should I choose RUIHE Silicone?
A: We can offer you the sample, sample test, technical support,
engineers' instruction, new products development, new market
expansion, factory visiting reception, latest silicone news in
China, related products purchasing assistance, 15-year experience

Q: Which shipping method can we choose?
A: You can choose your usual logistics company and logistics method.
Q: How long can I expect to get the sample?
A: 5-7 working days.
