Lubrizol Advanced Materials PEARLBOND® 102 Linear Thermoplastic Polyurethane (discontinued **)
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	PEARLBOND® 102 is a linear, polycaprolactone-based polyurethane, supplied in form of small white pellets, which combines a very high crystallization rate with a very high thermoplasticity level. Applications: PEARLBOND® 102 is mainly used for making heat-sealable fabrics (Thermobonding), obtained by coating processes such as scattering or dot-coating (powder or paste). In all cases, the product is previously ground into powder, by cryogenic grinding. The particle size of the powder will depend on the application technique to be used. Pearlbond® 103 is used for textile coating for making shoe-stiffeners (toe puffs & counters), by extrusion or sintering process.
