Supplier: Dotmar Engineering Plastics

To identify these two materials can be difficult but a simple test using a 20 cent coin is a great start.

Simply drag a 20 cent coin over the materials sheet surface. If the 20 cent coin digs into the material leaving a jaggedindentationit's most likely HDPE

If using the same 20 cent coin over the sheet surface the coindigs in but flows smoothly over the sheet, then this suggests that it's UHMWPE

If you would like assistance in the identification of your materials then please do not hesitate to contact a member of the Dotmar team in your region.
