Extruded ABS Plastic Sheet Black 1mm to 20mm
ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic engineering plastic, which is synthesized by emulsion polymerization or graft copolymerization of three monomers: acrylonitrile (A), butadiene (B) and styrene (S). Its sheet form (ABS Sheet) is a sheet material with uniform thickness made by extrusion or injection molding, with a thickness range of 1mm to 250mm and a width of 1m.
Advantages of abs sheet
The performance of ABS sheet is determined by its ternary copolymer structure, which combines rigidity, toughness and processing flexibility
Mechanical properties
Balance of high strength and toughness: Acrylonitrile provides rigidity (tensile strength of 40-60 MPa), butadiene gives high impact toughness (Izod notched impact strength ≥ 20 kJ/m²), and styrene improves processing fluidity.
Fatigue resistance: Excellent performance under cyclic loads, suitable for dynamic parts (such as car dashboard brackets).
Processing performance
Easy to form: Wide melting temperature range (180-250℃), can be formed by extrusion, injection molding, hot pressing, vacuum blister and other processes, suitable for complex structures (such as 3D curved panels).
Dimensional stability: Low linear thermal expansion coefficient (about 7×10⁻⁵/℃), small deformation under temperature fluctuations.
Chemical resistance and environmental adaptability
Solvent resistance: Good resistance to weak acids, alkalis, alcohols, greases, etc., but not resistant to strong oxidants (such as concentrated sulfuric acid).
Weather resistance improvement: By adding UV absorbers (such as hindered amine light stabilizers HALS) and antioxidants, the outdoor service life can be extended (up to 5 years or more).
Environmental protection and functionalization potential
Recyclability: It is a thermoplastic plastic that can be melted and recycled multiple times (recycling rate ≥ 90%), which is in line with the trend of circular economy.
Functional modification: Customized performance can be achieved through nano-filling (such as montmorillonite to enhance flame retardancy), blending (such as PC/ABS alloy to improve heat resistance) or surface coating (such as antistatic treatment).
Economical efficiency: Compared with engineering plastics (such as PC, POM), ABS has low raw material cost (about 1.5-3/kg), low processing energy consumption, and significant comprehensive cost advantages.
Applications
ABS sheet applications cover traditional industries and emerging high-tech fields. In recent years, the innovation directions include lightweight, functional integration and sustainability.
Automobile manufacturing
Interior parts: instrument panel, central control panel, door panel (need to meet VOC low emission requirements, use low odor ABS).
Exterior parts: bumper trim, spoiler (high gloss surface achieved by electroplating or spraying).
New energy vehicle parts: battery pack shell cover (need to pass UL94 V-0 flame retardant certification), charging port shell.
Electronic appliances
Equipment shell: printer, copier, household appliance panel (need antistatic treatment, surface resistance ≤10⁹ Ω).
Connectors and brackets: use its high dimensional stability to fix precision electronic components (such as 5G base station antenna brackets).
Architecture and decoration
Partitions and signs: sterile partitions in hospitals and laboratories (antibacterial coating is required to inhibit the growth of bacteria such as E. coli).
Advertising display: UV printing grade ABS sheet (surface roughness Ra≤0.8μm, suitable for high-precision inkjet printing).
Medical equipment
Disposable instruments: syringe trays, culture dishes (must pass ISO 10993 biocompatibility test).
Rehabilitation equipment shell: wheelchair parts, orthosis brackets (must be resistant to disinfectant corrosion, such as 75% ethanol wiping).
Emerging fields
New energy: photovoltaic inverter shell (must be resistant to high temperature yellowing, long-term use temperature can reach 85℃), wind turbine control box.
3D printing: sheet derivatives of ABS filaments, used for rapid prototyping (FDM printing support structure).
Aerospace: non-load-bearing parts (such as cable protective covers in cabins), which must pass airworthiness certification (such as FAA FAR 25.853 flame retardant standards).
