PC/ABS materials
PC/ABS is a polycarbonate and ABS blend whose composition and additives vary by grade. Blend behavior cannot be calculated directly from the individual polymers' data. Verify impact, flammability, appearance, chemical exposure and processing conditions for the actual grade.
PC/ABS handling and processing guide
This family-level guide is for preliminary screening, not a production recipe. Use the latest manufacturer instructions for the exact grade and equipment for drying, processing and safety settings; validate the process and part before production.
Storage
Protect against moisture and dust; segregate formulations, colors and flame-retardant grades, and avoid mixing with neat PC or ABS.
Drying
Follow the blend supplier's drying instructions, moisture target and hopper sealing requirements; do not directly reuse settings for neat PC or ABS.
Equipment setup
Adjust temperature, injection and holding settings using the blend processing sheet. Inspect appearance, weld lines, impact behavior and residual stress; validate painting or plating.
Typical applications
Candidate uses include automotive interiors, electronics housings and panels. Confirm flame, appearance and impact requirements for the exact formulation.
How to screen and compare grades
Start with the part’s operating temperature and exposure time, load, contact media, dimensional requirements and intended process. Compare specific manufacturers and grades: results with different test methods, specimen conditions, units or reinforcement are not automatically equivalent. A missing field means the information is unknown, not zero.
From data sheets to part validation
Use the database to build a shortlist, then request original data sheets, processing guidance and applicable certification from each manufacturer. Mold representative parts using the intended process and check dimensions, strength and function under the relevant combination of temperature, media and load; retain processing and lot records. Family-level guidance is not a guarantee for a particular grade.
