Lubrizol Advanced Materials PEARLBOND® 121 Linear Thermoplastic Polyurethane

Pearlbondâ„¢ 121 is a linear, polycaprolactone-based polyurethane, supplied in form of small white granules, which combines an extremely high crystallization rate with a very high thermoplasticity level. It is used for Hot Melt adhesives.Application: Pearlbondâ„¢ 121 is mainly used for textile coating for making shoe-stiffeners (toe puffs & counters), by extrusion or sintering process. Pearlbondâ„¢ 121 can be 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.
