Olefin block copolymers (OBC) are polyolefin elastomers composed of alternating soft and hard blocks The soft blocks deliver flexibility and the hard blocks deliver heat resistance. This block structure offers a good performance balance of flexibility, heat resistance, elastic recovery, abrasion resistance, and processability.
Common applications for OBCs are as polymer modifiers, foams, elastic films, adhesives, soft grips, toys, flooring, housewares, hose and tube, soft wheels, cap liners and various injection molded components.
