Press Release: Translucent Silicone for Pharma, Semicon and BioProcess

M-Cor Inc. Launches Breakthrough Teflon®-Encapsulated Translucent Silicone O-rings

HELENA, MT — Press Release Translucent Silicone : M-Cor Inc., a leader in advanced sealing solutions, has unveiled a next-generation innovation: Teflon®-encapsulated translucent silicone seals. This breakthrough product redefines purity, reliability, and process control for industries where failure and contamination is not an option—semiconductor, pharmaceutical, aerospace, and biologics.

Why It Matters

• Built for Inspection & Traceability
  The translucent, peroxide cured silicone core allows visual inspection of the seal itself, enabling real-time detection of contamination, leaks, or process deviations—an industry first for encapsulated O-rings.

• Chemical and Thermal Excellence
  A seamless PFA Teflon® jacket shields the silicone from aggressive solvents, gases, and sterilization cycles. With a wide operating range from cryogenic lows of -60 to 260°C, the seal maintains integrity under the harshest conditions.

• Purity Without Compromise
  Low outgassing, minimal particle generation, no red oxide and material compliance with FDA, USP Class VI, and NSF standards ensure suitability for ultrapure water, biologics, and cleanroom systems.

• Smarter by Design
  The combination of silicone resilience and Teflon® non-stick surfaces delivers leak-tight performance, resists adhesion, and simplifies cleaning—cutting downtime and improving throughput.

• Engineered for Flexibility
  Available in micro-sizes for precision instruments and large-scale extrusions for production equipment, these seals adapt to critical environments without design tradeoffs.

Raising the Standard

M-Cor’s translucent silicone encapsulation is more than an incremental improvement—it’s a new standard for purity and process monitoring. By combining visibility, compliance, and performance in one seal, engineers gain confidence, speed, and flexibility in the most demanding applications.
