Silicone Elastomer Seals for Industrial Applications

An elastomer seal is a flexible, rubber-like component designed to prevent leakage of fluids or gases between mating surfaces. Elastomer seals can be configured as O-rings, washers, bonded seals, or custom-molded shapes and are manufactured from materials such as silicone (VMQ), NBR, FKM, or EPDM, each suited to specific pressure, temperature, and chemical conditions.

No. Silicone is a specific type of elastomer. The broader elastomer family includes NBR, FKM/Viton, EPDM, and HNBR, among others. Silicone (VMQ) stands out for its exceptional temperature range (-60°C to 225°C) and biocompatibility, making it the preferred elastomer choice for food-grade, medical, and high-temperature industrial sealing applications.

Silicone (VMQ) elastomer seals typically operate from -60°C to 225°C, making them one of the widest temperature-range materials available. This makes VMQ seals suitable for both cryogenic environments and high-temperature industrial processes, including automotive engine components, food processing equipment, and aerospace applications.

Yes. Detroit Sealing Components' LSR (Liquid Silicone Rubber) products are manufactured in a Class 1000 cleanroom using a closed-loop automated process, meeting food-grade compliance and biocompatibility standards. These seals are suitable for medical devices, pharmaceutical equipment, food processing, and drinking water systems.

Absolutely. DSC offers custom engineering and design services for silicone elastomer seals, including metal-bonded rubber seals (10mm–320mm), LSR components, and rubber washers. Our team uses computer-aided design and finite element analysis to produce precision components in custom sizes, hardness levels (40–90 Shore A), and configurations for static and dynamic applications.

Silicone elastomer seals are used across a wide range of industries, including automotive, food & beverage, medical and healthcare, pharmaceutical, aerospace, oil & gas, renewable energy, agriculture, electronics, and drinking water systems. Their chemical resistance, temperature stability, and biocompatibility make them a versatile solution across critical sealing applications.
