EPDM – Ethylene-Propylene-Diene-Monomer

EPDM, a synthetic rubber, is an elastomer that is used in a wide range of applications. This material has outstanding resistance to abrasion, hydraulic fluids, alkalis, heat, ozone, and weather. It is also resistant to polar substances and steam.

Resilience: Very Good

Resistance to fatigue: Very Good

Resistance to Weathering: Excellent

Service Temperature Range: -75° to +350° F

Chemical Resistance: Excellent

Solvent Resistance: Excellent

Silicone Rubber

A family of high-performance synthetic materials, part mineral and part organic, also known as polysiloxane. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures. This material has excellent resistance to sunlight, weather, ozone, oxidization, and water. It also has very good resistance to flame.

Resilience: Excellent

Resistance to fatigue: Excellent

Resistance to Weathering: Excellent

Service Temperature Range: -76° to +446° F

Chemical Resistance: Excellent

Solvent Resistance: Fair

Neoprene

This material is included in a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene shows good resistance to sunlight, ozone, oxidization, and water. This material exhibits resistance to moderate chemicals, acids, oils, and solvents.

Resilience: Excellent

Resistance to fatigue: Good

Resistance to Weathering: Excellent

Service Temperature Range: -22° to +302° F

Chemical Resistance: Good

Solvent Resistance: Fair

PemkoPrene® – Thermoplastic Elastomer (TPE) – Thermoplastic Rubber (TPR)

These are rubber-like materials that can be processed like conventional thermoplastics. Because of its unique properties, the material offers excellent design freedom in the field of architectural door seals. These materials were selected because of their outstanding resistance to cleaning fluids and disinfectants as well as for their everyday resilience.

Resilience: Good

Resistance to fatigue: Good

Resistance to Weathering: Excellent

Service Temperature Range: -22° to +122° F

Chemical Resistance: Excellent

Solvent Resistance: Excellent

Flexible PVC – Vinyl

Flexible PVC or “vinyl” is a thermoplastic polymer material that is widely used in the construction industry largely because it is inexpensive and durable. The material has good chemical resistance to adhesives and most mild cleaning solutions.

Resilience: Poor

Resistance to fatigue: fair

Resistance to Weathering: Excellent when appropriately stabilized

Service Temperature Range: -4° to +122° F

Chemical Resistance: Good

Solvent Resistance: Good
