Platinum-Cured Encapsulated Silicone: Engineered by M‑Cor for Purity Applications
M‑Cor compounds and extrudes high-performance platinum-cured silicone materials specifically designed for fluid transport tubing and a wide range of complex, high-purity Teflon® encapsulated seals. Our in-house engineering ensures consistent quality, biocompatibility, and performance in the most demanding applications—from pharmaceutical manufacturing to semiconductor processing.
Why Platinum-Cured Silicone?
Platinum-cured (addition-cure) silicone offers superior purity, mechanical strength, and sterilization durability when compared to traditional peroxide-cured elastomers. It is translucent, non-yellowing, and contains virtually no extractables—making it ideal for sanitary and regulatory-compliant environments.
Key Advantages
- Non-leaching, high-clarity elastomer for visual inspection
- Meets USP Class VI, ISO 10993, FDA 21 CFR 177.2600
- Low compression set ensures seal longevity
- Thermal stability from −60 °C to +230 °C
- Gamma, steam, and autoclave sterilization compatible
M‑Cor Transport Tubing Capabilities
We extrude ultra-clear platinum-cured silicone tubing with optimized elongation and kink resistance. Designed for peristaltic pump applications and single-use bioprocess systems, our tubing exhibits:
- Stretchability up to 1000% elongation
- Temperature resistance from −100 °F to +400 °F
- Validated BPOG extractables profiles for biopharma
- Custom ID/OD configurations with short lead times
Complex Teflon® Encapsulated Seals
For ultra-aggressive chemicals or high-pressure applications, M‑Cor manufactures a complete line of Teflon® encapsulated O-rings, gaskets, and sealing profiles. Each unit features a platinum-silicone or FKM core within a seamless FEP or PFA shell—engineered for durability and low gas permeation.
- Encapsulation materials: PTFE, FEP, and PFA
- Core options: solid or hollow platinum-cured silicone
- Shapes: standard AS568, ISO 3601, spiral-wound, and custom molded
- Chemical compatibility up to 98% of aggressive fluids
