-
Regulatory-Grade Fluoropolymer Encapsulation: The silicone core is encapsulated in a durable layer of FEP or PFA, providing exceptional chemical resistance, thermal stability, and mechanical strength without compromising elasticity.
-
Sterilization Resilience: These seals retain performance integrity through repeated autoclaving, CIP/SIP processes, and high-temperature sterilization, making them a superior alternative to conventional seals.
-
Precision & Traceability: Designed for traceability and consistency, M‑Cor’s seals meet or exceed FDA, USP, and SEMI industry standards.
Target Applications in High-Stakes Industries
Because process purity and compliance are paramount, M‑Cor’s encapsulated platinum-cured silicone is ideally suited for:
Pharmaceutical & Biotech Manufacturing: Ensures clean sealing in mixing, filtration, and fill-finish systems.
Semiconductor & Electronics Fabrication: Prevents contamination in wafer production, etching, and deposition chambers.
These industries rely on M‑Cor for seals that maintain their shape, elasticity, and performance across rigorous cycles of heat and chemical exposure.
