New TPV (TPE-V) products have been recently developed, especially for applications in automotive interiors with requirements of low fogging and surface durability. These materials are based upon polypropylene and a finely dispersed fully crosslinked polyolefin elastomer. The product is non-hygroscopic, very easy-to-color, fully weatherable, and processable with injection molding or extrusion equipment. Light colors can be made with very low levels of color concentrate, which helps to retain the designed engineering properties of the TPV after coloring. Compression set characteristics of these materials are comparable to other TPV products. Chemical resistance is very good, including resistance to surface damage from oily consumer products such as suntan lotions and baby oil. The thermal-mechanical properties of the new TPV-AP products have been tested at temperatures from 25degrees to 150 degreesC. Stress relaxation behavior of the new TPV is very comparable to existing commercial phenolic resin cured TPV.
