HIGH STRENGTH NON-CHLORINATED MULTI-LAYERED POLYMERIC ARTICLE |
摘要 |
<p>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).</p> |
