Lubrizol Advanced Materials PEARLBOND® 100 Linear Thermoplastic Polyurethane
Categories: Polymer; Thermoplastic; Polyurethane, TP

Material Notes: Pearlbond™ 100 is a linear, polycaprolactone-based polyurethane, supplied in form of small white granules, which combines a very high crystallization rate with a very high thermoplasticity level. It is used for Hot Melt adhesives.

Application: Pearlbond™ 100 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.
