Main features of silicone gaskets:

Super high and low temperature resistance

The operating temperature range is very wide, usually -60℃ to +200℃, and special formulas can even reach -100℃ or +250℃. It is one of the most reliable sealing materials in high/low temperature environments.

Excellent softness and elasticity

Silicone itself is soft and elastic, suitable for fitting various irregular or precision surfaces. Even if it is compressed for a long time, it is not easy to deform permanently, and the seal is long-lasting and stable.

Excellent insulation

Good electrical insulation performance, stable dielectric constant, non-conductive, so it is suitable for gaskets, insulating layers, thermal conductive gaskets, etc. in electronic equipment.

Non-toxic and odorless, good biocompatibility

Medical grade or food grade silicone can be in contact with the human body or food for a long time, and is widely used in medical equipment, food machinery and other fields, and complies with FDA, LFGB and other certifications.

Aging resistance, ozone resistance, UV resistance

Long-term use will not age or crack due to sunlight, wind, ozone and other environments, and is an ideal material for outdoor or long-term sealing.

Waterproof and dustproof, good airtightness

After processing and molding, it can form a highly sealed structure, which is suitable for IP67 or higher sealing requirements (such as electronic housings, outdoor equipment).

2. Common application scenarios:

Medical equipment: blood pressure monitors, ventilators, dental equipment seals

Food machinery: oven door seals, water dispensers, food-grade gaskets

Electronic appliances: mobile phone waterproof rings, router gaskets, power supply seals

Automotive industry: lamp seals, instrument panels, sensor protection pads

Industrial equipment: high temperature seals, flange gaskets, airtight isolation layers

Household items: pot lid seals, microwave gaskets, non-slip foot pads

3. Common shapes and types of silicone gaskets:

Flat gaskets (disc type): used for sealing between flange surfaces and housings

O-ring structure: suitable for cylindrical connection seals

Frame gaskets / embedded sealing strips: used for frame waterproof and dustproof

Thermal conductive silicone gaskets: added with ceramic powder or graphite, used for electronic heat dissipation

Foamed silicone gaskets: with microporous structure, soft, high compression rate, suitable for buffering and sound insulation occasions
