1. Mix ratio:component A: component B=1000 parts :1000 parts.
2. Clean mixing mill. Mix rubber until smooth edge and surface of the rubber formed by double roller mill.
3. Extrusion process---Discharge the mixed rubber from mixing mill , cut it to appropriate dimension, then do extrusion process.
4. Suggested curing condition: 400ºC--600ºC by vertical oven.
5. The press molding condition can be adjusted according to the dimension of product.
Package:
20kg/box
Storage:
1. Separately store component A and component B
2. Stored in cool, dry and ventilated place
3. Environmental temperature below 30ºC
Shelf life:

Handling precautions:
1. Long time stored fully mixed rubber can be remixed for using. But inspection needed to confirm the properties
2. Separately store component A and component B as well as vulcanizing reagents.
3. Safe processing temperature including mix rubber should be below 65ºC.
4. Safe storage time of mixed A/B is 2 days below temperature 25ºC.
Safety precautions:
1. Wear personal protect equipment to avoid burning while processing. Do not eat.
2. Handle with care, details refer to MSDS. In addition, please follow safety regulation of country or local government.
Q: What is solid silicone rubber?
A: Solid silicone rubber is a polymer material connected by silicon-oxygen bonds. It has rubber-like elasticity but is solid at room temperature.
Q: What are the characteristics of solid silicone rubber?
A: This kind of silicone rubber usually has excellent high temperature resistance, chemical stability and electrical insulation properties. It has both good mechanical strength and wear resistance.
Q: What are the application fields of solid silicone rubber?
A: Solid silicone rubber is widely used in aerospace, automobile manufacturing, electronic devices, medical equipment and other fields that require high temperature resistance, electrical insulation or chemical corrosion resistance.
Q: What is the difference between solid silicone rubber and liquid silicone rubber?
A: Compared to liquid silicone rubber, solid silicone rubber is solid at room temperature, not liquid or semi-liquid. It has higher density and lower permeability.
Q: What is the preparation method of solid silicone rubber?
A: The preparation of solid silicone rubber usually involves the reaction of raw materials such as silicon source, vulcanizing agent and processing aids. After a curing or vulcanization process, silicone rubber with specific properties is formed.
Q: What should I pay attention to when using solid silicone rubber?
A: When using solid silicone rubber, the curing process, temperature and environmental conditions should be controlled according to the specific application requirements and manufacturer's guidelines to ensure optimal performance.
