摘要:
Thermoplastic elastomer mixture which comprises at least one thermoplastic elastomer TPE, with the exception of a thermoplastic polyurethane TPU, and at least one filler from the group of precipitated silica, or precipitated silicate or carbon black.The thermoplastic elastomer mixtures are produced by, in a first step, mixing at least one filler selected from the group of precipitated silica, or precipitated silicate or carbon black, and at least one thermoplastic to give a masterbatch and, in a second step, mixing the masterbatch with at least one thermoplastic elastomer, with the exception of a thermoplastic polyurethane TPU.The thermoplastic elastomer mixture can be used in injection-molded items.

摘要:
Processing aid comprising a) 10-50% by weight of hydrophobized, at least partially aggregated, metal oxide particles b) 20-75% by weight of one or more thermoplastic polyurethanes, c) 0.5-50 by weight of one or more prepolymers comprising isocyanate groups the sum of the constituents a) to c) amounting to at least 80% by weight, based on the processing aid.
摘要:
Thermoplastic elastomer, which comprises a fumed, hydrophilic or hydrophobic silica, which has been structurally modified and also a process for the improvement of the mechanical properties of thermoplastic elastomers. The thermoplastic elastomers are produced by preparing a masterbatch from the components (e.g. thermoplastic resin component and fumed silica) and compounding this with further thermoplastic elastomers.
摘要:
A processing aid is used in the processing of thermoplastic polyurethanes to give various articles including a self-supporting film. The processing aid contains a) 10-50% by weight of hydrophobized, at least partially aggregated, metal oxide particles selected from the group consisting of aluminium oxide, silicon dioxide and mixtures thereof, b) 20-75% by weight of one or more thermoplastic polyurethanes, c) 0.5-25% by weight of one or more isocyanates, d) 0.5-15% by weight of one or more compounds which act as lubricant and dispersant, the sum of the constituents a) to d) amounting to at least 90% by weight, based on a total weight of said processing aid.
