DESIGN, MANUFACTURE & SUPPLY OF PERFORMANCE BUCKLES & FASTENINGS SINCE 1981

Material Specification


Buckles, Fasteners and associated accessories are generally made from one of two materials, Nylon or Acetal.

Acetal
Acetal 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.

Acetal Special Grade
Acetal Special Grade is a toughened Acetal. This material possesses all of the positive attributes of standard Acetal combined with superior resistance to impact loads. Designed to withstand the toughest of environments and excessive treatment, Acetal Special Grade is recommended for military applications for personal load carriage in particular.

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 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
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.

Flame Retardant Grilon
BS V0 is a, self extinguishing PA6 injection moulding material that is Halogen and Phosphorous free.

Polypropylene
Polypropylene Webbing is manufactured from Polypropylene material which is UV stable yarn to minimise fading this gives great strength, wear resistance and durability.
