New Self-Bonding LSR Reduces Medical Silicone Production Step
Keywords: self-bonding liquid silicone rubber, medical LSR, FDA 177.2600, low volatile silicone, overmoulding silicone
Key sentence: This self-bonding medical-grade liquid silicone rubber eliminates mandatory post-curing while keeping volatile content below 0.5% by volume.
A new self-bonding LSR grade for medical and food contact silicone applications is attracting attention from medical device moulders in November 2026. It bonds firmly to PBT, PET and polyamide substrates during overmoulding, without extra surface primer treatment. It meets FDA 177.2600 and BfR food contact standards, targeting baby care silicone goods, wearable medical sensors and disposable medical seals. Traditional medical LSR usually requires long post-curing cycles to lower volatile organics; this reformulated silicone saves oven time and improves moulding throughput for high-volume silicone mould shops. Tear strength reaches 38 N/mm per ASTM D624B, suitable for thin-wall flexible silicone parts. Medical silicone manufacturers can shorten lead times and reduce reject rates for overmoulded assemblies. It is offered in 40 and 50 Shore A durometers, covering most common medical silicone overmoulding projects.
