Plastic parts can be identified by the SAE code, which is usually found on the rear of the part, and/or by the characteristics of the plastic.
Knowing the type of plastic aids in selecting the proper repair materials and in selecting the proper repair procedure.
Look for the SAE code stamped into the part.
Match the code to those in the plastic identification chart to determine whether the plastic is thermoplastic or thermoset plastic, and whether the plastic is rigid or flexible. Refer to Plastic Identification and Refinishing Systems
No Code Found
Warning: Do NOT use a plastic burn test to distinguish the type of plastic. The burn test produces vapors which are harmful.
Perform one or both of the following tests to determine if the part is thermoplastic polyolefin or thermoset non-polyolefin.
The shaving should be free of mold release agents and paint.
Thermoplastic and thermoset plastics can be either rigid or flexible. Thermoplastic plastic parts are best repaired with a hot iron plastic material-feed welder, but are usually replaced. Thermoset plastic can be repaired with epoxy or other more rigid 2 package repair material.
For general repair instructions, refer to General Plastic Repair.
