Description

Poly(Styrene-Co-Acrylonitrile) (CAS NO 9003-54-7) is a high-performance thermoplastic copolymer engineered to combine the processability of polystyrene with the enhanced chemical resistance and strength of polyacrylonitrile. This material is valued for its excellent dimensional stability, rigidity, and good surface finish, making it a versatile solution for demanding applications. It is primarily sought after by manufacturers in the automotive, electronics, and consumer goods industries for producing durable components that require a balance of mechanical properties and aesthetic quality.

Application

• Automotive Components: Used for interior trim, instrument panels, and housings for switches and controls due to its rigidity and good surface finish.
• Electronics Housings: Ideal for casings of appliances, power tools, and office equipment where dimensional stability and a quality appearance are critical.
• Consumer Goods: Manufactured into items such as cosmetic containers, brush handles, and disposable razors, leveraging its gloss and moldability.
• Medical Device Housings: Employed for non-implantable medical equipment enclosures that require chemical resistance to cleaning agents.
• Battery Cases: Suitable for certain battery housings where resistance to electrolytes and good structural integrity are needed.
• Plumbing Fixtures: Used in components like faucet handles and showerheads that benefit from its stain resistance and durability.
