Plastic Parts Finishing: Reference

Plastic parts employ not only ABS (Acrylonitrile Butadiene Styrene) plastic but also polypropylene, vinyl, or the like plastic. Burning test method to identify ABS plastic is described below.

1. Use a sharp blade to cut off a plastic sliver from the part at its hidden backside.
2. Hold sliver with pincers and set it on fire.
3. Carefully observe condition of the burning plastic.
4. ABS plastic must raise readily distinguishable back smoke while burning with its residue suspended in air temporarily.
5. Polypropylene must raise no readily distinguishable smoke while burning.
