Product details
ABS Sheet (Acrylonitrile - Butadiene - Styrene Copolymer Sheet)
ABS Sheet (Acrylonitrile - Butadiene - Styrene Sheet) is a sheet-shaped engineering plastic formed by extrusion or injection molding with ABS resin as the base material. ABS is a terpolymer formed by emulsion polymerization or graft copolymerization of three monomers: acrylonitrile (Acrylonitrile, A), butadiene (Butadiene, B) and styrene (Styrene, S). Its molecular chain structure combines the chemical resistance and high strength of acrylonitrile, the toughness and impact resistance of butadiene, and the rigidity of styrene, forming a high-performance material with a balance of "rigidity - toughness - resistance".
Since its industrial production in the 1950s, ABS sheets have been widely used in the fields of automobiles, electronics and electrical, architectural decoration, etc. due to their easy processing, high cost performance and excellent comprehensive performance, becoming one of the indispensable basic materials in modern manufacturing. In recent years, with the advancement of modification technology, ABS sheets have been continuously upgraded in terms of flame retardancy, heat resistance, conductivity, etc., further expanding their application boundaries.

Physical and chemical properties
Chemical corrosion resistance
Resistant to organic solvents: Stable to non-polar solvents such as gasoline, diesel, and mineral oil, but sensitive to ketones (such as acetone), esters (such as ethyl acetate) and strong polar solvents (such as chloroform); Acid and alkali resistance: Resistant to weak acids (such as phosphoric acid and acetic acid) and weak bases (such as sodium hydroxide solution, concentration ≤10%), but easily corroded by concentrated sulfuric acid and concentrated nitric acid.
Weather resistance and heat resistance
Weather resistance: General-grade ABS sheets tend to turn yellow under ultraviolet light (anti-UV agents need to be added), while heat-resistant ABS sheets (with α-methylstyrene copolymer added) can have a long-term use temperature of 80-100°C (short-term temperature resistance of 120°C);
Heat deformation temperature: The heat deformation temperature (1.82 MPa load) of general-grade ABS sheets is 70-90°C, while the flame-retardant ABS sheets can be reduced to 60-80°C due to the addition of flame retardants, and the heat-resistant ABS sheets can reach 100-110°C.
ABS Plastic Sheets
Precise processing performance
Processing temperature range: extrusion temperature 180 - 230℃, injection temperature 190 - 250℃, good melt fluidity (melt index MI = 5 - 20 g/10min), suitable for complex shape molding (such as thin-walled parts, special-shaped structures);
Processing tolerance control: Through precision injection molding or extrusion process, the thickness tolerance can reach ±0.1 mm (±0.2 mm for ordinary plastic sheets), surface roughness Ra≤1.6 μm (Ra≤0.8 μm after polishing), suitable for high-precision assembly (such as electronic equipment housing).
Economical
Cost-effectiveness: The price is only 1/3 of PC (polycarbonate) and 1/2 of POM (polyoxymethylene), which significantly reduces material costs while meeting medium strength requirements.
ABS sheet has become a core material in the fields of automobiles, electrical and electronic products, and architectural decoration, thanks to its balanced performance of "rigidity, toughness, and durability", easy processing, and low cost. In the future, through functional integration, sustainable upgrading, and intelligent manufacturing adaptation, its application scenarios will be further expanded to high-end fields such as aerospace (such as drone fuselages) and medical devices (such as implantable device housings), and continue to promote the development of the global manufacturing industry towards high performance and green development.
