PC/ABS Resin

What is a PC/ABS Resin Material Blend?

PC/ABS (polycarbonate / acrylonitrile-butadiene-styrene terpolymer blend) is a thermoplastic alloy of (PC) polycarbonate and (ABS) acrylonitrile-butadiene-styrene. Both PC/ABS materials are well known amorphous plastics. Alloying these two materials enhances processability, and provides non-halo flame retardancy.

Polycarbonate (PC) is a rigid thermoplastic that provides clarity, toughness, and good heat resistance. By itself, polycarbonate has reasonable resistance to burning, and that resistance increases by adding flame retardants that are typically halogen-containing. Acrylonitrile-butadiene-styrene is a well know rigid thermoplastic that offers both moderate impact and moderate chemical resistance. The heat resistance of acrylonitrile-butadiene-styrene is lower than that of polycarbonate. Like polycarbonate, halogen containing additives are used to increase resistance to burning.

Most polymers tend to undergo a decrease in viscosity as shear rates increase. That behavior allows modest increases in injection pressure to help fill injection molded parts. Since polycarbonate very gradually decreases in viscosity as shear rates increase, it can be a challenge to process. While ABS is used in many applications, the usefulness of ABS is limited by medium heat resistance, and by medium impact performance. Flame retardant grades of both PC and ABS primarily use “halogen FR technology,” and use of that technology can limit applications. These limitations can be overcome by using compounding technology to produce PC/ABS alloys.

ABS PC – It’s Tough

Unlike PC, alloys of PC and ABS do undergo a significant decrease in viscosity as shear rates are increased. This allows PC ABS resin  to be processed more easily than pure PC. PC ABS materials  are very tough materials. Although they are not as tough as PC alone, they are much tougher than ABS. They also have much higher heat resistance than pure ABS. A “non-halogen” flame retardant technology is used in FR PC/ABS blends. This expands the applications for this tough, moderate heat resistant material.

Although Polymer Resources offers PC/ABS blends in a wide range of melt flows, we are always willing to produce products within a 5 unit sub-range to suit a customer’s specific needs.

ABS PC – Powerful and Versatile

ABS PC is a high-performance thermoplastic combining heat, strength, and impact resistance. This versatility makes ABS PC a sought-after material in the automotive and electronics industries. 

ABS PC offers powerful benefits, whether it’s durable automotive components or protective electronics housings.

ABS PC Additives, Modifiers, and Reinforcing Agents:

  • Additives – UV stability, easy release (mold releases), colorants, and other stability additives
  • Modifiers – Flame retardants, impact modifiers, flow enhancers

Q. Is PC/ABS a copolymer?
A. No, polycarbonate/acrylonitrile-butadiene-styrene is a blend of two engineering thermoplastics (as indicated by the slash “/”). Such blends are often referred to as “polymer alloys.” An alloy provides a material with properties of each component of the blend. The PC/ABS alloy provides higher impact than ABS and easier processability than PC. The alloy is also a compromise in that some of the chemical resistance of ABS is lost, as well as the clarity of PC.
Q. What is PC/ABS used for?
A. In the automotive industry, PC/ABS is used for internal components such as glove boxes, instrument panels and consoles. In electronics, it can be used in computer and business machine housings, TV frames, mobile devices and keyboards, just to name a few applications.
Q. Is PC/ABS brittle?
A. No, both components of the blend are ductile. As a result, the blend is ductile and has higher impact (toughness) than ABS alone.

In general, the impact behavior of polymers is heavily dependent upon temperature. At higher temperatures, plastics are more ductile and demonstrate high impact. However, at temperatures drop below 20F, some materials start to become brittle. This brittleness tendency increases as the temperature decreases. The ductile to brittle transition point depends upon the glass transition temperature (Tg) of the material.

Q. Is PC stronger than ABS?
A. Yes, PC is a hygroscopic resin, meaning that it absorbs moisture internally, typically from humidity in the air. This process can cause changes in dimensions, mechanical strength and dielectric properties. Resins like PC are typically dried before molding to optimize the processability and performance of the end application.
