    Hello , I want to ask some questions. My company ordered the Ultra-High Molecular Weight Polyethylene - UHMWPE from the supplier. When we got the materials , the dimension of our material is incorrect. Thus , we asked the supplier , they said that the air Conditioner's temperature effect the dimension. We are quite doubt with the supplier. So before anything , does Pe-UHMW shrink on cold temperature ? If it shrink , what are the solution to overcome this situation ?
