PC/ASA Resin

What is PC/ASA Resin Material Blend?

ASA and PC/ASA The acrylic-styrene-acrylonitrile terpolymer (ASA) is an amorphous thermoplastic material that offers good resistance to both UV and moisture. PC/ASA is an amorphous thermoplastic alloy of polycarbonate (PC) and ASA that provides enhanced heat resistance and enhances mechanical properties.

Additives, Modifiers, and Reinforcing Agents:
  • Additives – UV stability, easy release (mold releases), colorants, and other stability additives
  • Modifiers – Flame retardants, impact modifiers, flow enhancers
  • Reinforcing Agents – Glass fibers, mineral fillers

Q. What kind of material is PC/ASA?
A. Polycarbonate (PC)/acrylic-styrene-acrylate (ASA) is a blend (indicated by the “/”) of two engineering thermoplastics. Such blends are often called alloys because they combine desirable properties of each component. The PC/ASA alloy is an opaque material that offers weatherability and excellent thermal and mechanical properties. Key mechanical properties include dimensional stability, toughness, rigidity and hardness. Blends of PC and ASA provide higher toughness and a higher heat deflection temperature (HDT) than ASA alone, and better weatherability and easier processing than PC alone. PC/ASA alloys can be used in injection molding, blow molding, extrusion and thermoforming processes.
Q. What is PC/ASA used for?
A. Polycarbonate/acrylic-styrene-acrylate is used largely in unpainted automotive exterior and interior parts requiring excellent aesthetics and weatherability, such as mirror housings and grilles. Other sectors that use PC/ASA include building and construction (window profiles), lawn and garden and sporting goods. Polymer Resources’ new flame-retardant PC/ASA compound stands out in the industry by achieving a UL V-0 rating at 1.5mm for all colors. The new material uses a non-halogenated flame retardance system, which contributes to customers’ sustainability goals. Featuring excellent weatherability, it is ideally suited for enclosures of outdoor electrical equipment and housings for medical and dental devices exposed to strong interior lighting and UV sterilization.
Q. What is the difference between PC/ASA and PC/ABS?
A. Acrylic-styrene-acrylate improves upon acrylonitrile-butadiene-styrene (ABS) by increasing UV resistance. The resins are structurally similar, but ASA surpasses ABS in retention of gloss, color and mechanical properties under outdoor exposure. In fact, ASA has about 10 times the weathering and UV resistance of ABS, as well as higher long-term heat resistance and better chemical resistance.
Q. Is ASA better than ABS?
A. As mentioned above, the main difference between ASA and ABS is UV stability (weatherability). Since ASA is more expensive to produce than ABS, the latter is often preferred if weatherability is not a major concern.
