What is high-consistency rubber (HCR)?
High-consistency rubber (HCR) is a type of silicone elastomer known for high molecular weight and excellent mechanical properties, including durability, flexibility and resistance to extreme temperatures. HCRs are millable thermoset silicone elastomers that can be extruded continuously to form desired sizes and shapes before curing to create robust, biocompatible parts. While HCRs are particularly ideal for silicone tubing and medical devices, other common applications include seals, gaskets and components for healthcare and other industrial sectors.
Our product portfolio
Biomedical-grade HCRs with sustained performance for critical long-term implant applications (>29 days)*
*Use of this material for implantation ≥30 days requires indemnification. It is the user’s responsibility to ensure the safety and efficacy of these materials for all intended uses. While these materials have passed screening tests that are applicable to products intended for implantation, DuPont makes no representation concerning the suitability of these products for applications of greater than 29 days of implantation in the human body.
Class VI HCRs with sustained performance for critical short-term implant and non-implant applications (<30 days)**
**It is the user’s responsibility to ensure the safety and efficacy of these materials for all intended uses. While these materials have passed screening tests that are applicable to products intended for implantation for up to 29 days, DuPont makes no end-use representation based on such testing. Nor does DuPont make any representation concerning the suitability of these products for applications of greater than 29 days of implantation in the human body.
