How to distinguish the quality of EPDM rubber sheet

EPDM rubber sheet

To distinguish the quality of EPDM rubber sheet, the following methods can be used:

Observe the color: True EPDM rubber has a pure color, slightly dull, rather than very bright or dark. If the color looks particularly dull or too bright, it may be a sign of poor quality.
Smell its odor: True EPDM rubber, after being vulcanized and filled, has no pungent odor of ordinary rubber, but a fragrant smell. If a pungent odor is detected, it may indicate poor quality.

Touch its texture: True EPDM rubber has excellent texture and feels smooth when touched. If it feels rough, it may be of poor quality.

Combustion method: While not recommended as a regular method, it can be used to quickly judge by burning a small sample. True EPDM rubber burns with white smoke and a fragrant smell, while inferior materials emit black smoke and have a pungent odor.

These methods can help users initially judge the quality of EPDM rubber sheet, but when making an important purchase decision, it is advisable to refer to more professional inspection reports or consult professionals.
