30 Durometer Commercial Grade Solid Silicone — Technical Overview & FAQs
Product Overview
30 Durometer Commercial Grade Solid Silicone Rubber is an extra-soft, high-flexibility silicone elastomer designed for applications requiring low compression force, excellent sealing, and stable performance across extreme temperatures.
At 30 Shore A, this grade is one of the softest solid silicones available, making it ideal for delicate sealing surfaces, low-fastener-load gaskets, and applications requiring high elasticity and conformability without sacrificing durability.
This material exhibits outstanding UV, ozone, and weather resistance, maintains flexibility at low temperatures, and provides long-term stability in electrical enclosures, LED lighting, transportation, medical equipment, and industrial sealing applications.
Applications
Low-compression environmental and dust seals
Delicate housings, enclosures, and thin-wall structures
Medical, pharmaceutical, and lab equipment (non-FDA grade unless specified)
LED lighting and optical enclosure gaskets
Automotive, aerospace, and transportation sealing
Flexible pads, spacers, strips, and die-cut components

FAQs
What is 30 Durometer Commercial Grade Solid Silicone used for?
It is used for low-pressure sealing, flexible gaskets, environmental barriers, and high-elasticity seals in electronics, transportation, medical equipment, and industrial assemblies.
How soft is 30 durometer silicone?
30A silicone is one of the softest solid rubber grades, providing excellent flexibility and low compression force, ideal for delicate or thin-walled enclosures.
Is this silicone suitable for outdoor use?
Yes — silicone rubber provides excellent UV, ozone, and weather resistance, making it suitable for long-term outdoor environments.
Does 30 durometer silicone withstand high temperatures?
Yes — silicone materials operate reliably up to 450 °F (232 °C) and maintain flexibility at very low temperatures.
Can this material be die-cut or produced with adhesive backing?
Absolutely — H-O Products supplies die-cut gaskets, strips, sheets, PSA-backed parts, and extruded profiles tailored to OEM requirements.
