Polyamide 6, glass-fibre reinforced 15 %, thermoforming grade

Machining PA6 GF15 black

Glass-fibre reinforced PA6 in thermoforming grade for large, thin-walled mouldings. We machine precision parts to drawing, from batch size 1.

Overview

What is PA6 GF15 black?

PA6 GF15 black is a 15 % glass-fibre reinforced, impact-modified polyamide 6 developed as extruded sheet specifically for thermoforming (vacuum forming). It combines the high strength, creep resistance and dimensional stability of a reinforced polyamide with very good formability – for large, thin-walled mouldings that could otherwise only be produced economically by injection moulding.

Frequently asked questions

PA6 GF15 black in detail

1What is PA6 GF15 black?+

PA6 GF15 black is a 15 % glass-fibre reinforced, impact-modified polyamide 6 developed as extruded sheet specifically for thermoforming (vacuum forming). It combines the high strength, creep resistance and dimensional stability of a reinforced polyamide with very good formability – for large, thin-walled mouldings that could otherwise only be produced economically by injection moulding. PA6 GF15 black achieves a yield stress of 105 MPa, a tensile modulus of 5,400 MPa and a heat deflection temperature of 190 °C at a notched impact strength of 12 kJ/m². The glass fibres keep creep low even under permanent load and give the mouldings high stiffness; the material is resistant to oils, greases and fuels, UV-stabilised, easy to machine and bondable. Like all polyamides, the material absorbs moisture (up to 2.5 %), which affects dimensions and stiffness; sheets must be dried before thermoforming.

2How does Liedtke machine PA6 GF15 black?+

PA6 GF15 black is formed as sheet in the vacuum thermoforming process; the sheets must be dried beforehand, and forming temperature and holding time depend on sheet thickness and tooling. The mouldings can then be trimmed and machined using all conventional cutting methods; carbide tools are recommended because of the abrasive glass fibres. Good cooling via chip removal avoids heat build-up; bonding is readily possible with suitable adhesives after surface pretreatment.

3When should I choose PA6 GF15 black?+

PA6 GF15 black is used wherever large, stiff and impact-resistant mouldings are required in small and medium quantities – for example in vehicle and commercial vehicle construction, in mechanical engineering and in container construction:

  • Panels, covers and housing parts for vehicles and machines
  • Thermoformed containers, trays and tubs
  • Load-bearing mouldings in contact with oil and fuel
4What determines the price of a PA6 GF15 black part?+

PA6 GF15 black is calculated individually based on drawing or sample. The part price is mainly determined by the stock form and dimension, material utilisation (waste), machining effort and batch size. We are happy to quote binding prices on request.

5When is PA6 GF15 black not the right choice?+

Just as important are the limits of the material:

  • Moisture absorption affects dimensions and stiffness
  • Low elongation at break, abrasive to tools
  • Not generally declared for food contact (see FDA declaration)
6Advantages and disadvantages of PA6 GF15 black+

An honest assessment:

  • Advantage: Very good thermoformability for large mouldings
  • Advantage: High strength, creep resistance and dimensional stability
  • Advantage: Heat deflection temperature 190 °C, resistant to oils and fuels
  • Advantage: Easy to machine and bond, UV-stabilised
  • Disadvantage: Moisture absorption affects dimensions and stiffness
  • Disadvantage: Low elongation at break, abrasive to tools
  • Disadvantage: Not generally declared for food contact (see FDA declaration)
