Abstract
The present disclosure is directed to pulverulent thermoplastic polymer blends comminuted to a particle size of less than 300 μm. The pulverulent thermoplastic polymer blends can include a first thermoplastic polyurethane and a second thermoplastic polyurethane at a weight ratio of from about 90:10 to about 30:70 first thermoplastic polyurethane to second thermoplastic polyurethane. The first thermoplastic polyurethane can include a reaction product of a first reaction mixture consisting of or consisting essentially of an aliphatic diisocyanate having a number average molecular weight of from 140 g/mol to 170 g/mol and an aliphatic diol having a number average molecular weight of from 62 g/mol to 120 g/mol. The second thermoplastic polyurethane can include a reaction product of a second reaction mixture comprising a polyisocyanate, an isocyanate-reactive component having a number average molecular weight of from 500 g/mol to 10,000 g/mol, and a chain extender having a number average molecular weight of from 60 g/mol to 450 g/mol.
