An extrusion molded gasket and a method of making such a gasket comprising one or more annular sections configured to engage a door rim of an appliance tub, one or more annular sections configured to engage the appliance tub, and one or more sealing sections disposed therebetween, wherein the gasket comprises at least one thermoplastic vulcanizate comprising at least 15 wt %, by weight of the thermoplastic vulcanizate (TPV), of a cross-linkable ethylene-based elastomer and within a range from 5 to 30 wt %, by weight of the TPV, of at least one thermoplastic, the TPV having a Shore Hardness within a range from 35 A to 100 A (or 50 D), and wherein the TPV is extrusion molded into the gasket.

Extrusion molded thermoplastic vulcanizate gaskets and methods of making such gaskets

A thermoplastic vulcanizate composition comprises: (i) a dispersed phase of rubber that is at least partially cured; (ii) a continuous thermoplastic phase including at least one thermoplastic polymer; (iii) a first polysiloxane composition comprising a migratory siloxane polymer physically dispersed in a first thermoplastic material and (iv) a second polysiloxane composition comprising a non-migratory, siloxane polymer bonded to a second thermoplastic material.

Thermoplastic vulcanizates

A thermoplastic vulcanizate composition comprises: (i) a dispersed phase of rubber that is at least partially cured; (ii) a continuous thermoplastic phase including at least one thermoplastic polymer; (iii) a first polysiloxane comprising a migratory liquid siloxane polymer; and (iv) a second polysiloxane comprising a non-migratory siloxane polymer bonded to a thermoplastic material.

Thermoplastic elastomer compositions, in particular derived from one or more styrenic block copolymers wherein at least one styrenic block copolymer comprises a controlled distribution copolymer block including a conjugated diene and a mono alkenyl arene, a plurality of biorenewable materials, preferably a softener and one or more synergistic additives such as a polar polymer; a synergistic block copolymer such as a relatively high molecular weight styrenic block copolymer; and/or filler. Numerous desirable articles can be formed from the compositions. Processes for preparing the compositions and articles are disclosed.
