Liquid Injection Molding Silicone for tube making

Liquid Injection Molding Silicone for tube making 

Description of  Injection Molding Silicone Rubber:

liquid silicone rubber(LSR) for Injection molding is a two-part high purity addition cured silicone specifically designed for liquid injection molding, which can be fully automatically injection molded without secondary processing. They are platinum curing and vulcanize under heat and pressure.

Typical Prosperities and application of Injection Molding Silicone Rubber :

 HY-E642# is an injection molding liquid silicone rubber for Baby care products such as Baby nipples, pacifier, toothbrush and other food grade injection products. They are elastomer cured under high temperature, has the following excellent properties:

1 High transparency

2 Excellent tear Strength (>3.5KN/m)

3 Good resilience

4 Good heat stability and weatherability(temperature resistant range from -60°C to 250°C)

5 Anti-yellowing

6 Heat-ageing resistance

7 Comply with USA CFR21.Part.177.2600 and Chapter 4.9 Test Standards for Volatile Compound of EN14350-2 and EU RoHS Standard

Curing Condition:

After Mixed A with B according to mixing ratio of 1:1, 150mm X 150mm X 2mm, mould will be formed in 7minutes under temperature of 150 °C

Package:The general packages of HY-E642#  is 20kg or 200kg per barrel.

Notice:

After the component A and component B are mixed under the temperature of 20 °C, the effective operating time is 5 days in sealing status, The effective operating time will shorten in case of rising temperature.

The viscosity, hardness and appearance/color of above products can be adjusted according to customer’s specific requirements.
