FUNCTIVE Additive for ABS and PC/ABS Blends
Enhanced Chemical Resistance at Low Addition Levels
Minimal Effect on Mechanical Properties
ABS and PC/ABS offer substantial performance advantages including thermoformability, dimensional stability (resistance to warpage) and impact resistance. However, these materials suffer from poor chemical resistance which affects mechanical properties and clarity for transparent grades. Fortunately, FUNCTIVE was developed to improve the chemical resistance while maintaining other properties. A summary is presented on this page. For more detail, request the whitepaper. Samples are also available.
FUNCTIVE Improves the Chemical Resistance of ABS
Test method:
The injection-molded test piece was fixed on the ¼-oval test piece described on page 8 and 9, and chemicals were applied to it. The samples were left for 20 hours under the condition of 23°C and 50RH%, and the critical strain value (ε) was calculated from the crack occurrence position.
- Critical strain value 1: Poor chemical resistance (ε<0.7)
- Critical strain value 2: Average chemical resistance (0.7≦ε<0.8)
- Critical strain value 3: Good chemical resistance (0.8≦ε)
- Critical strain value 4: Excellent chemical resistance (No cracks)

FUNCTIVE has Minimal Effect on the Mechanical Properties of ABS
Materials:
According to the above table, each of the compounds was kneaded using a single screw extruder at 250oC, and then molded using an injection molding machine (nozzle temp.: 250oC, mold temp.:50oC).
ABS resin and FUNCTIVE were dried at 80oC for 3hours.
