Full list of ABS material characteristics and usage

June 16, 2022

Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)x· (C4H6)y·(C3H3N)z) is a common thermoplastic. Its melting point is approximately 105 °C (221 °F).


ACRYLONITRILE - imparts chemical resistance and rigidity.

BUTADIENE - endows the product with impact strength, toughness and abrasion resistance.

STYRENE - contributes to the lustre, ease of processing and rigidity.ethods including cold solvent cement welding or our rubber


The advantage of ABS is that this material combines the strength and rigidity of the acrylonitrile and styrene polymers with the toughness of the polybutadiene rubber.

Generally ABS would have useful characteristics within a temperature range from 10 to 80 °C (50 to 176 °F).
