The amorphous thermoplastic EV Acrylonitrile Styrene Acrylate (ASA), also known as acrylic styrene acrylonitrile and commonly utilised in the automobile industry, was created as a replacement to acrylonitrile butadiene styrene (ABS) but with enhanced weather resistance.
It is a copolymer of styrene and acrylonitrile modified with acrylate rubber. Because of its mechanical qualities and UV resilience, it is a great material for usage in fused deposition modelling printers, where it is utilised for general prototyping in 3D printing.
Acrylonitrile-styrene-acrylic ester terpolymer (ASA) possesses exceptional weathering resilience, excellent glossiness, resistance to chemical assault, high heat resistance, and ease of processing.
The structural similarities between ASA and ABS are composed of butadiene and acrylonitrile rubber, and they maintain the excellent mechanical and physical properties that engineering plastics like ABS have.
Instead of the divinyl rubber found in ABS that contains an unsaturated double bond, the acrylic rubber used in ASA lacks this component.
As a result, the material’s ability to resist UV ray-induced degradation as well as ageing, fading, decomposition caused by high temperatures during processing in the air or variations in colour is significantly improved.
The Global EV acrylonitrile styrene acrylate market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
During the time of forecasting, it is anticipated that the ASA market will expand significantly. ASA polymers are being used more frequently in the automotive, building and construction, and other end-user industries as a result of its superior qualities to other thermoplastic materials like ABS.
Other industries it is encroaching on include packaging, sports equipment, consumer electronics, and home appliances.
ASA differs from other materials in that it offers important qualities including heat and age resistance, high surface polish, high tensile strength, and chemical resistance; these qualities are enhancing the use of ASA, particularly in the automotive industry.
ASA is utilised in the creation of the instrument panel, interior components, lights, hoods, electrical components, and other aspects of a vehicle.
