Pearlbond™ ECO D900

Technical Datasheet | Supplied by Lubrizol
Linear, aromatic polyurethane based on specialty polyol from renewable sources. It is supplied in form of small white or lightly yellowish granules, which combines an extremely high crystallization rate with a very high thermoplasticity level. It is mainly used for textile coating for making shoe-stiffeners (toe puffs & counters), by extrusion or sintering process. 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. It contains 75% of renewable material as certified according to ASTM-D6866.
