General Material Descriptions

General Material Descriptions:

Acetal (A) is a crystalline thermoplastic polymer material. Acetal characteristically has excellent tensile strength, stiffness, surface hardness and chemical resistance. Acetal has excellent flexural memory and property retention when subjected to repeated loading. The normal short-term use temperature range is -40°F to +270°F (-40°C to +132°C). Acetal is recommended for high performance applications. Physical properties remain consistent across a wide range of temperature, relative humidity, and weather conditions.

Nexcel (PP) is a crystalline thermoplastic polyolefin-based polymer material. Nexcel is lightweight material. Nexcel has good tensile strength, stiffness, chemical resistance and flexural memory. In general, the properties of Nexcel are well below those of Acetal. The normal short-term use temperature range is 0°F to +270°F (-18°C to +132°C). Nexcel provides good product integrity, but is recommended only for basic and low performance applications. Physical properties remain consistent across a wide range of relative humidity conditions, but fall off at low temperatures.

Supertough Nylon (N2) is an impact modified crystalline thermoplastic polyamide resin. The defining Supertough Nylon characteristic is superior resistance to repeated impact loads. This material maintains good tensile strength, chemical resistance, stiffness and flexural memory. Nylon is excellent in high temperature applications. The normal short-term use temperature range is –40°F to +390°F (-40°C to +199°C). Nylon is, however, a hydroscopic resin. Therefore, physical properties will vary as the relative humidity changes. When dry, tensile strength is higher and impact is lower. When wet, tensile strength is low and impact strength is very high. Supertough is recommended for specific products or applications where extreme impact resistance is needed.

Nylon 6/6 (N1) is a thermoplastic polyamide resin. This material maintains good tensile strength, chemical resistance, stiffness and flexural memory. Nylon is excellent in high temperature applications. The normal short-term use temperature range is –40°F to +390°F (-40°C to +199°C). Nylon is however, a hydroscopic resin, therefore, physical properties will vary as the relative humidity changes. When dry, tensile strength is higher and impact is lower. When wet, tensile strength is lower and impact strength is higher.

Elastomeric Resin (E) is a thermoplastic material. It is a flexible plastic that bridges the gap between rubbery elastomers and rigid plastics. In general, it exhibits good low temperature flexibility, good toughness, chemical resistance and excellent abrasion resistance. Normal short-term use temperature range is 0°F to +293°F (-18°C to +145°C). Material properties will change drastically outside of this range. This temperature range is material-based and individual parts may perform differently.

Nexomer (N) is a proprietary blend of thermoplastic elastomeric resins.  Nexomer provides fatigue ressitance as well as resistance to creep and UV damage for active applications.  Physical properties remain consistent across a wide range of temperature, relative humidity, and weather conditions.  Normal short-term use temperature range is -40F to 300F (-40C to 150C).
