Frequently Asked Questions about Silicone Gaskets

A silicone gasket is a mechanical seal made from silicone, that fills the gap between two surfaces. Silicone gaskets are flexible, durable, and can withstand a wide range of temperatures and conditions, making them a versatile material.

When you’re looking for multi-temperature range, high-performance mechanical seals with high resilience and durability, you should consider silicone gaskets.

There are several types of silicone gaskets, each designed for specific applications and conditions.

  • Solid Silicone Gaskets
  • Sponge Silicone Gaskets
  • Silicone Foam Gaskets
  • Food-Grade Silicone Gaskets
  • Medical-Grade Silicone Gaskets
  • Silicone O-Rings
  • Conductive Silicone Gaskets
  • High-Strength Silicone Gaskets

There are several common advantages of silicone gaskets, as following:

Thermal stability: Silicone gaskets can withstand temperatures between -40 and 250° C. They remain flexible at both low and high temperatures without becoming brittle or losing their shape and durability.

FDA approved: Silicone is an FDA-approved material, meaning silicone gaskets can be used in industries such as food processing, healthcare, medical, and others that require non-toxic materials.

Environmental resistance: High-temperature silicone gaskets are flame-retardant for use in high-heat applications like telecommunications and mass transportation. They are ideal for outdoor applications due to their resistance to water, UV, ozone, and various temperatures. Silicone gaskets can also hold up to various chemicals, including solvents, oil, acids, bases, and more.

Durability: Due to its resistive properties, silicone offers excellent durability. This makes them a cost-effective option because they can last a long time without showing wear or requiring maintenance.

Electrically conductive: Silicone gaskets conduct electricity, allowing them to provide electromagnetic interference (EMI) shielding for electrical components.

Silicone gaskets are used in a wide range of applications due to their excellent properties such as high-temperature resistance, flexibility, and durability. Here are some common applications of silicone gaskets:

Food and Beverage Industry:
Processing Equipment: Food-grade silicone gaskets are used in equipment like mixers, ovens, and sterilizers to ensure sanitary conditions.
Bottle and Jar Seals: Used in food packaging to provide airtight seals and preserve freshness.

Medical and Pharmaceutical Industry:
Medical Devices: Medical-grade silicone gaskets are used in devices like pumps, respirators, and diagnostic equipment for their biocompatibility.
Sterilization Equipment: Used in autoclaves and other sterilization equipment where high temperatures are involved.

Industrial Applications:
Machinery Seals: Provide sealing in various industrial machinery and equipment, including pumps, compressors, and valves.
HVAC Systems: Used in heating, ventilation, and air conditioning systems for sealing and insulating ductwork.
Water and Waste Treatment: Used in sealing applications in water and wastewater treatment plants.

Consumer Products:
Household Appliances: Used in appliances such as ovens, dishwashers, and refrigerators for sealing and insulation.
Wearables: In products like watches and fitness trackers for waterproofing and durability.
