Erapol 1K Blocked Series

Erapol 1K Blocked Series are polyester-based, one component blocked elastomers that cure with heat. The range currently consist of products from 20 Shore A to 90 Shore A. The 1K series are stable at room temperature. As one component products there is no secondary mixing with an added component required to set the product. The blocked systems contain no free isocyanate, no MOCA (MbOCA) or any solvents.
