Neoprene Compression Set

Parker's 70 durometer black Neoprene (CR), C1276-70 provides good ozone, aging, and chemical resistance as well as being the go to material for refrigerants. This is considered our "super neoprene " which provides a lower compression set than other CR materials. Temperature range: -35°F to 250°F (-37°C to 121°C) Chemical resistance.

New Super Neoprenes deliver superior long-term compression set , refrigerant resistance for longer seal life. The Super Neoprene family consisting of compounds C1276-70, C1277-75 and C1278-80 provide resistance to a broad range of refrigerants and lubricants, while performing in a broader temperature range than existing Neoprene formulations, e.g. C0873-70.

The neoprene itself passes compression set testing when the testing is done on molded "buttons" as per the applicable ASTM testing procedure - but the neoprene fails when samples are taken from the production part. RE: Improving Neoprene Compression Set GrahamBennett (Materials) 22 Apr 10 09:20.

Environmental and Chemical Resistance. Silicone supports a wider range of temperatures and has better compression set , but Neoprene offers higher abrasion resistance and tensile strength. The table below describes some common material properties for each elastomer for comparing silicone vs. neoprene rubber. Silicone.

Compared to conventional neoprene , this ultra-strength neoprene rubber exhibits excellent recovery from compression and is so and durable that it doesn’t fail over thermal cycling and wet, oily or abrasive environments.Ultra-strength neoprene rubber is tested for heat resistance, ozone resistance, compression set , oil resistance and cold condition flexibility.
