Olefin-based thermoplastic elastomers
ABOUT
By adding rubber or fillers to olefin resins, flexibility and impact resistance that cannot be obtained with olefin resins alone are imparted.
This is a non-crosslinked olefin-based thermoplastic elastomer in the medium to high hardness range.
*As of April 2017, the medium and high hardness grades of "Thermorun™" have been renamed to "Tefabloc™.
*TPO refers to a mixture containing olefin-based elastomer components.
*The product name used on the packaging, delivery specifications, SDS, etc., for this product will be "Tefabloc™".
