Grupor® Copolymer

Grupor® Copolymer



Expandable copolymers is a category of plastics combining the advantages of various thermoplastics. For instance, protective helmets are produced from Grupor® copolymer. In this connection, the high degree of energy absorption is used if the EPP is deformed. The difference between the copolymers and the simple EPP in is the way each absorbs energy. The copolymer largely absorbs the energy by breaking the cell combination. The recovery properties of EPP are “eliminated” in favour of greater energy absorption by the copolymer.
