Smoke Flame Toxicity Neoprene Extrusions - 65 Duro

Kismet Rubber Products manufactures high-performance smoke flame toxicity neoprene extrusions and gaskets engineered for safety-critical environments. Trusted by OEMs across the mass transit industry, we deliver precision rubber components that meet strict smoke, flame and toxicity standards.

When passenger safety is at stake, our custom solutions help keep your systems compliant and dependable, day after day.

Engineered for Safety: Low-Smoke, Flame-Resistant Neoprene

Kismet’s smoke flame toxicity neoprene is a low-smoke, flame-resistant compound made for the demanding requirements of mass transit OEMs. This medium-hardness, 65 durometer neoprene is ideal for both extruded and molded rubber components, providing reliable performance in the most safety-critical settings.

We build this material for real-world conditions. It resists chemicals, water, and ozone without breaking down or compromising performance. OEMs count on it to create durable gaskets and extrusions for passenger rail systems, where compliance and longevity matter just as much as precision.

FAQs: Smoke Flame Toxicity Neoprene Gaskets and Extrusions

What industries require smoke flame toxicity neoprene?

Industries such as mass transit, aerospace, and defense utilize neoprene compounds that are smoke flame toxicity-resistant to meet stringent safety regulations for fire, smoke, and toxicity exposure.

Why is 65 durometer neoprene ideal for transit applications?

65 durometer neoprene offers the right balance of flexibility and strength for transit gaskets and extrusions. It seals effectively under pressure, withstands vibration and movement, and maintains performance across a wide range of temperatures and conditions.

Can Kismet customize extrusions for unique window geometries?

Yes! Kismet designs and manufactures custom neoprene extrusions to match even the most complex window geometries in passenger rail systems.
