Non-styrene based polymers

Float testing

Place the sample in a small bowl of water that has had some detergent added to it .

 

Note: you must have the detergent or surface tension will prevent the sample from behaving as it should. For foam samples this test obviously does not work !

Results

Sample floats - generally a polyolefin.

Sample sinks - not generally a polyolefin.
