Fluorosilicone rubber vulcanization molding conditions

The optimal vulcanization molding conditions for fluoro silicone rubber vary depending on the specific formulation and application of the rubber. However, some general guidelines for fluoro silicone rubber vulcanization molding conditions are:

1. Temperature: The vulcanization temperature should typically be between 150°C and 200°C, depending on the specific formulation. Higher temperatures can cause the rubber to degrade or become too elastic, while lower temperatures can result in insufficient crosslinking.

2. Time: The vulcanization time should be sufficient to allow for complete crosslinking of the rubber, typically ranging from 5 minutes to 30 minutes.

3. Pressure: The molding pressure should be sufficient to ensure that the rubber completely fills the mold cavity and achieves proper contact with the mold surfaces. The pressure can range from 50 psi to 500 psi, again depending on the specific formulation.

4. Curing agent: A curing agent is typically needed to facilitate the crosslinking reaction. The type and amount of curing agent should be tailored to the specific rubber formulation and molding conditions.

5. Mold release: A mold release agent should be used to prevent the rubber from sticking to the mold surfaces during the molding process.

Overall, the key to successful fluoro silicone rubber vulcanization molding is to carefully select and optimize the molding conditions for the specific formulation and application of the rubber.
