Each sheet has a waxy texture with one side gloss and the other matt. Neither side is covered with protective film (normal for engineering plastics) so we are unable to guarantee a totally scratch free surface. If high impact resistance is required or a plastic that will easily bond, other plastics such as harder nylon and acetal could be better options. HDPE sheets are difficult to bond to anything and needs to be physically or mechanically fixed in place rather than bonded. Please call or email our friendly plastic experts for advice and assistance in choosing the most appropriate plastic for your purposes.
