  • Process for preparing a crosslinked polyolefin foam
    Publication number: 20050062184
    Abstract: The process of the invention is characterized by the unidirectional expansion of a composition containing a substantial proportion of at least partially crosslinked and/or crosslinkable polyolefin, in order to form a product made of foam, especially relatively compliant foam. The use of a polyethylene or ethylene copolymer obtained by metallocene catalysis is preferred.

  • Flexible cellular material, composition and process for its preparation
    Publication number: 20020153633
    Abstract: A flexible cellular material can be made by extruding a composition containing a polyurethane prepolymer, where the prepolymer has end groups selected from the group consisting of isocyanate end groups and trialkoxysilyl end groups, and the prepolymer is self-crosslinkable with moisture. The flexible cellular material has an expanded or foamed polymer matrix.
