Improvements in Spray Polyurethane Technology

摘要

Sprayed aromatic polyurethane elastomers are an alternative to traditional cover stock in both automotive and nonautomotive applications. This technology was developed in response to requests for materials with better cold flex, fogging, odor, and abrasion resistance properties as well as improved styling freedom and grain definition, with reduced environmental impact. Recent developments in this technology at BASF allow for improved processing, low VOC system with improved heat and humid aging properties. This paper describes the application process and physical properties of Elastoskin? polyurethane spray systems and introduces the improvements that BASF has made to these systems.
