Lubrizol Advanced Materials Pearlbond® D170 Thermoplastic Polyurethane (discontinued **)
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	Pearlbond® D170 is a TPU grade designed for use with Heat Sealable Fabrics. This grade is to be applied in thermo bonding (heat-sealing) processes, through which the adhesive is laid on a series of substrates (mostly fabrics), then treated with heat and pressure so as to bond them. In some cases, these TPUs are applied, after being ground into powder, through one of the usual methods: scatter coating, paste coating, powder point coating, double dot coating and engraved roller. Pearlbond® TPU benefits are valued in numerous applications. Applications for which D170 is specially suited are: Textile: Lamination, bonding of textile, linings for leather goods, clothing and footwear Footwear: Shoe uppers, sole bonding, shoe stiffeners Properties of Pearlbond D170: Very high crystallization rate. Very high thermoplasticity range.
