HIGH CONSISTENCY SILICONE RUBBER
71 Hardness Shore A High Consistency Silicone Rubber CHR Curing agent C1
PRODUCT DESCRIPTION
High consistency silicone rubber (HCR) is a type of silicone rubber that is highly durable and resistant to extreme temperatures. It is commonly used in various industrial applications, including automotive, aerospace, and healthcare for manufacturing seals, gaskets, and O-rings. HCR is typically processed by compression or transfer molding, and it can be produced in a range of colors, including transparent. The material has excellent biocompatibility, making it an ideal choice for medical devices and implants.

APPLICATION
Parts that have been postcured are appropriate for food contact applications and comply with the Recommendation "XV. Silicones" of the BFR and FDA § 177.2600, provided that any limitations regarding extractable and volatile substances are observed.
FEATURES
1. High consistency silicone rubber (HCR) has excellent thermal stability, which means it can withstand high temperatures without degrading or losing its properties. This makes it ideal for use in high-temperature applications, such as automotive and aerospace industries.
2. HCR has good chemical resistance, making it resistant to many chemicals, solvents, and oils. This property allows for its use in applications where exposure to chemicals is likely.
3. HCR has good mechanical properties, such as high tensile strength, excellent tear resistance, and good compression set resistance. This makes it ideal for use in demanding applications such as seals, gaskets, and other parts that require durability.
4. HCR is also highly flexible and has good elasticity, making it suitable for a wide range of applications that require flexibility and elasticity, such as hoses, tubing, and other flexible parts.
5. High consistency silicone rubber (HCR) is highly resistant to UV radiation, ozone, and weathering, which makes it ideal for outdoor applications that require long-term exposure to sunlight and other environmental factors.
6. HCR has excellent electrical insulation properties and is often used in the electrical and electronics industries to manufacture insulators, connectors, and other parts that require electrical insulation.
SAFETY NOTES
1. Store HCR in a cool, dry place away from direct sunlight and heat sources.
2. Keep the material in its original container, which should be tightly sealed to prevent air or moisture from entering.
3. Avoid storing HCR near chemicals, solvents, or other materials that could contaminate or damage it.
4. Use the oldest batches of HCR first to prevent them from expiring or losing their properties.
5. If storing HCR for an extended period, periodically check the material for signs of hardening, discoloration, or other changes that may indicate deterioration.
By following these storage guidelines, you can ensure that your HCR remains in good condition and is ready for use when needed.
