Ikke-chloreret flerlagspolymergenstand med høj styrke

摘要

A multi-layered article 10 includes a fabric 12 having a polymeric sheet 14, 16 secured to each side of the fabric 12. Each polymeric sheet 14, 16 secured to the fabric 12 has two non-chlorinated polymeric layers. The first non-chlorinated polymeric layer A, A' is disposed on the inner side of each sheet and contains an ethylene copolymer that has a Shore A hardness less than 85. The second non-chlorinated polymeric layer B, B' is disposed on the outer side of each sheet and contains a polymer having a Shore A hardness greater than 85. The multi-layered article 10 demonstrates good flex-crack resistance to make it suitable for use in a roll-up sign 30 or a truck trailer cover 40.
