Plastic Hardware material specifications


The following material specification is used for identification of manufacturers materials and their properties. All data is obtained from the suppliers of raw materials. It does not represent a binding guarantee. TR reserves the right to change manufacturer without notice.

The test material according to UL (Underwriters Laboratories Inc) allow classification of polymers according to their flame retardance.

With a horizontal and vertical test of fire behaviour under the influence of an open flame. Detailed information on UL can be downloaded at The ratings are: UL94 -HB/V2/V1/V0.

The temperature ranges of the various materials are guidelines received from the respective raw material manufacturers. It does not represent a binding guarantee. TR Fastenings reserve the right to change manufacturer without notice.

Support information - Plastic Hardware

Material: Nylon (RoHS)

The material used for the moulded products is nylon. Its many compositions have most of the properties that are required in the electrical/electronic industry such as:

  • Lightweight
  • Strength at low and high temperature
  • Resistance to impact, abrasion, organic solvents, and gasoline
  • Retention of shape and stiffness at high temperature
  • Flammability rating
  • Colour: natural and black. All other RAL-colours on request
  • ROHS - Material suppliers to certify compliance with the Restriction of Hazardous Substances (RoHS) in electrical & electronic products
  • Cost reduction where single application plastic part can replace multiple existing parts
  • Moisture: Nylon parts are hygroscopic (ability to hold water molecules drawn in from its surroundings). Therefore, when injection moulded, nylon parts retain latent heat from the manufacturing process and continue to absorb moisture

All our parts have water added before being packed in sealed plastic bags to ensure the integrity of the material and to prevent the parts from becoming brittle.

We strongly recommend continued storage of plastic parts in sealed bags.

Shelf life: All nylon products need be stored in the original, unopened bag at 22°C to 35°C and 50% relative humidity. If these conditions are met the shelf life will be one year from the date of shipment.

UL flame rating: UL94 classifications V0, V1, V2 and HB describe the flame retardancy levels for a given resin. V0 rated resins typically have the highest flame resistance followed by V1, V2 and HB.

Tolerances: xx  ±  0,25


Acrylic adhesive tape (release tab)

Shelf life: The adhesive used has a shelf life of 12 months if stored correctly. Adhesive parts should be stored in the original bags at room temperature of 22°C to 35°C.

Surface: The bonding surface must be clean, uniform, dry and free of condensation.

Do not use on fabric or rough, loose surfaces.

Release tab: Remove the releaser liner being very careful not to touch the adhesive surface and then quickly and firmly rub the product into place. Firm pressure is needed to ensure full contact.

Tapes are not Ul-rated

Material temperature range is: -20°C to +60°C.


RoHS directives

RoHS (Restriction on Hazardous Substances) refers to the Directive 2002/95/EC of the European Parliament of 27 January 2003 - This directive bans from 1 July 2006, the subsequent use of hazardous substances in electrical and electronic equipment. Lead, mercury, cadmium, hexavalent chromium, polybrominated Biphenlye (PBB), polybrominated biphenyl ethers (PBDEs).

The WEEE (Waste Electronic Equipment) refers to Directive 2002/95/EC of the European Parliament of 27 January 2003. This policy is primarily to avoid the waste of electrical and electronic equipment, as well as their recycling. Please contact us if you need information regarding the RoHS or WEEE.
