HIGH CONSISTENCY SILICONE RUBBER
Good Mechanical Properties HCR High Consistency Silicone Rubber with 51% Rebound Resilience
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
Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA
§ 177.2600 under observance of any given limitations on extractable and volatile substances.
STORAGE
Although storing a product beyond the date specified on the label does not necessarily render it unusable, it is advisable to conduct a quality assurance check on the product's properties required for the intended use.
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.
