Nylon or Acetal? What’s best for my buckle?

Here at Ace Supplies HQ, we get asked this question a lot. If we look at Acetal, Supertough Nylon and Nylon 6/6 individually we can see the differences in tolerances and recommended conditions.

Acetal is a crystalline thermoplastic polymer material. Acetal characteristically has excellent tensile strength, stiffness, surface hardness and chemical resistance. Acetal has good flexural memory and property retention when subjected to repeated loading. The service temperature range or operating temperature range for our products moulded from Acetal resin is -40F to 140F. Acetal’s recommended for high-performance applications. Physical properties remain consistent across a wide range of temperature, relative humidity, and weather conditions.

Supertough Nylon 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 ideal 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 resistance is very high.

Nylon 6/6 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 standard 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 resistance is higher.

In summary, the right material will be determined by your application, and please remember that it is the responsibility of the customer to ascertain the suitability of the products for use in their particular application.
