PPDI PPDI A process for PPDI based polyurethane elastomer nano-clay and PPDI based polyurethane elastomers thereby the same that

摘要

The present invention relates to a process for producing an elastomeric PPDI polyurethane nano-clay elastomer having a nano-clay content of 0.3 to 0.4% by weight, a hardness of at least 95 A, a tensile stress at 100% elongation of 12 MPa or more, And a mold PPDI-based polyurethane nano-clay elastomer produced thereby.
