Product description

Compression permanent deformation is the permanent deformation of rubber materials in the compression direction, and is an important performance when used as gaskets under high and low temperature conditions. After the test piece is fixed at a specified compression rate, it is placed at a specified temperature for a certain period of time. After the load is removed, it is placed for a certain period of time to allow it to recover freely. At this time, the remaining deformation that cannot be restored to its original state is called permanent deformation. Use residual deformation as a percentage of compression deformation as a characterization value. Among synthetic rubbers, thermally vulcanized silicone rubber has the smallest compression set and can maintain good compression set in a wide temperature range.



Main features

* Excellent and stable physical properties, low compression set.

* Pass ROHS certification, REACH SVHC certification, etc.



Three, the main application

* Silicone gaskets, sealing rings, gaskets, etc.



Four, typical product data

Five, use method and operation

1. Start mixing on an open mill for about 3-5 minutes, so that the rubber can be rolled and mixed evenly.

2. Add the color paste and mix evenly (if necessary), then add the vulcanizing agent, hit ten to fifteen rolls, so that the vulcanizing agent is evenly dispersed in the rubber, and the surface of the rubber becomes smooth.

3. Lower the roll and eject the film. Separate the two pieces with adhesive paper. For molding and vulcanization, it is recommended to add a double-two-five vulcanizing agent (about 1.2%)



Security and storage

* From the date of production, it should be stored at room temperature for six months; it is recommended to use it within three months. If it exceeds three months, the product mixing time should be appropriately extended.
