What is ABS natural?
ABS natural is an amorphous standard engineering thermoplastic based on acrylonitrile butadiene styrene copolymer. The combination of a stiff styrene-acrylonitrile matrix and an embedded butadiene rubber phase results in a material with high impact strength, good stiffness and excellent surface quality – at economical cost.

ABS natural in detail
1What is ABS natural?+
ABS natural is an amorphous standard engineering thermoplastic based on acrylonitrile butadiene styrene copolymer. The combination of a stiff styrene-acrylonitrile matrix and an embedded butadiene rubber phase results in a material with high impact strength, good stiffness and excellent surface quality – at economical cost. It combines a yield stress of 38 MPa and a tensile modulus of 2,000 MPa with a notched impact strength of 25 kJ/m², largely retained even at low temperatures down to −40 °C.
2How does Liedtke machine ABS natural?+
ABS natural can be machined well using all conventional cutting methods; sharp tools and good cooling via chip removal avoid heat build-up and stress cracking. Cooling lubricants must be compatible with ABS – ketones, esters and aromatic solvents must be avoided – if in doubt, machine dry or with compressed air. For tight tolerances and thick-walled parts, we recommend intermediate annealing to relieve machining stresses.
3When should I choose ABS natural?+
ABS natural is used wherever impact-resistant, dimensionally stable and visually appealing parts are to be produced economically at moderate temperatures:
- Housings, covers and panels
- Prototypes, models and fixture parts
- Brackets, handles and control elements
4What determines the price of an ABS natural part?+
ABS natural 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 ABS natural not the right choice?+
Just as important are the limits of the material:
- Continuous service temperature only 80 °C
- Not resistant to ketones, esters and aromatic solvents
- Limited UV and weathering resistance, normally flammable (UL 94 HB)
- Not generally declared for food contact
6Advantages and disadvantages of ABS natural+
An honest assessment:
- Advantage: High impact strength, even at low temperatures
- Advantage: Very good machinability, easy to bond, print and paint
- Advantage: Good stiffness and dimensional stability, good surface quality
- Advantage: Economical standard plastic
- Disadvantage: Continuous service temperature only 80 °C
- Disadvantage: Not resistant to ketones, esters and aromatic solvents
- Disadvantage: Limited UV and weathering resistance, normally flammable
- Disadvantage: Not generally declared for food contact (see FDA declaration)
