ASA Acrylonitrile-styrene-acrylate – Acrylonitrile–Styrene–Acrylate

ASA Acrylonitrile-styrene-acrylate – Acrylonitrile–Styrene–Acrylate

ASA use: Enclosures and panels for outdoor use , window frames, antenna devices, mailboxes, traffic lights, flag buds, both. Parts for cars as lamp bodies, grille, window frames and painted panels.

Fire: Fire can be developed various substances such as styrene, acrylonitrile and other organics.

Colors: Very color stable.

Trade names: Geloy® – Maclon® 600 – Luran S®.

History: Developed in 1960. The earliest attempts to produce ASA was of Herbig and Salyer from Monsanto who used butyl acrylate rubber base. This work was refined by Otto and Sibel from BASF as copolymerized butyl akrylate with butadiene to prepare rubber base.

 

Category: The plastic is an amorphous thermoplastic with very varying composition of the three components. See also ABS.

Chemical resistance: Worse Chemical resistance than ABS.

Chemical structure: Amorphous thermoplastics, Copolymer of acrylic, styrene and acrylonitrile.

Density 1,05 g/cm3

 

Mechanical properties: Worse impact strength when cold than ABS.

Surface treatment: Excellent surface treating.

Cleaning: Withstands hot wash and waxed car washes for cars.

Assembly (mechanical): Can be assembled with screws, bolts, rivets, staples, sewing or by clicking collections. ASA may have a different thermal expansion coefficient than the material, that it is attached to.

Injection molding: Excellent.

Cutting: Use sharp tools.

Welding: Butt Welding, hot air welding, Induktionssvejsning, friction welding.

 

Thermal Properties. Application temperature from -40 to + 70º C.

UV- Stability: ASA is very UV stable. After long-term outdoor use, it will not be gray , as typically is done with UV-stabilized ABS.

 

Thermoforming (Termoformning): Excellent.
