Acrylonitrile Butadiene Styrene/Polycarbonate Alloy - ABS/PC

May 4 2001

Polymer Type

Thermoplastic

Advantages

Improved stiffness over conventional high impact ABS.  Better processing properties than Polycarbonate.  Improved notched izod impact resistance compared to high impact ABS.

Disadvantages

Limited resistance to hot water.  Lower notched izod impact resistance ( c.  0.55 KJ/m - 10.3 ft lb/in ) compared to Polycarbonate ( c.  0.7 KJ/m - 13.1 ft lb/in ).
