Peel strength impact of functionalized polyethylene to thermoplastic polyurethane calendered on a polyester fabric

Résumé

Many producers use the extrusion calendering process for thermoplastic polyurethane coated fabrics. However, a technological lock is the ability to get a good adhesion of the coating with the fabric. Producers could increase the coating extrusion temperatures but TPU have a narrow extrusion temperatures range making it difficult to extrude. One solution is to make a blend with another polymer which has a higher extrusion temperature range. In the present work, the studies of the addition of LDPE and LLDPE-g-Ma in polyurethane coating on the tensile strength of the sheet and on the peel strength with a polyester fabric have been studied as well as the influence of the extrusion temperature. SEM observations and viscosity measurements have been performed to understand the behaviour of the different blends. Results show that extrusion temperature and penetration depth of the coating in the fabric have an influence on the peel strength.
