摘要： A thermoplastic elastomer compound is disclosed having a high strain recovery rate and a high strain fixity rate to provide shape memory, preferably manageable shape memory. The thermoplastic elastomer compound comprises styrene-ethylene/butylene-styrene and a paraffin wax having less than about 0.5% oil content. Shape modes of articles made from the thermoplastic elastomer compound can be altered by at least one thermo-mechanical event to cause deformation of the compound from a first shape to a second shape with retention of the compound in the second shape for any reasonable time interval.

摘要： A thermoplastic elastomer compound is disclosed having a high latent heat of fusion, indicative of a large thermal capacity. Use of thermal capacity agents, particularly linear paraffin waxes used in replacement of conventional plasticizer oils, contributes the thermal capacity advantages. Selection of the particular thermal capacity agent can provide an ability to engineer the amount of thermal capacity and the transition temperature in which that thermal capacity can be utilized as absorption or release of heat. The compound experiences a solid-solid phase transition whenever the thermal capacity agent melts into liquid form in the compound.

摘要： A blend of styrene-isobutylene-styrene based thermoplastic elastomer and organoclay-filled polyamide is disclosed which has good processability and more effective barrier properties for oxygen than the blend using amorphous or crystalline polyamide without organoclay.
