Polyvinyl chloride (PVC) is known for its firm and durable nature, while polyethylene terephthalate (PET) is often associated with food containers and beverage bottles.

Melting Behavior

Heat a small, inconspicuous area of the plastic using a lighter or heat gun. Different plastics exhibit distinct melting behaviors that provide clues to their identity. For example, PE melts smoothly and easily, while PP melts with a higher viscosity and forms long, stringy strands. PVC melts slowly with a pungent odor, and PET curls and shrinks.

Density

Compare the weight of the plastic to water by placing a piece in a container of water. Plastics like PE and PP float, whereas denser plastics such as PVC and PET sink. This information can help you narrow down the possible material types.

Plastic Type Physical Properties Melting Behavior Density
Polyethylene (PE) Milky or translucent, soft and flexible Melts smoothly Floats in water
Polypropylene (PP) Harder, more rigid texture Melts with high viscosity, forming strands Floats in water
Polyvinyl Chloride (PVC) Firm and durable Melts slowly with a pungent odor Sinks in water
Polyethylene Terephthalate (PET) Clear or colored, stiff and flexible Curls and shrinks when heated Sinks in water
