Methods for preparing articles from processable and dimensionally stable elastomer compositions |
October 27, 2009 |
| Methods for preparing a shaped rubber article, comprising admixing at least one thermoplastic material and at least one elastomer material to provide a processable and dimensionally stable rubber composition, shaping the composition, and irradiating the composition to form the shaped |

Electron beam inter-curing of plastic and elastomer blends |
April 21, 2009 |
| Two-phase or single-phase admixtures of a plastic and an elastomer, two or more thermoplastics, or two or more elastomers are irradiated (preferably with electron beam radiation) to cross-link the thermoplastic and, in the case of elastomer and thermoplastic admixtures, generate bi-modal |

Electron beam curing of fabricated polymeric structures |
November 18, 2008 |
| Admixtures either of a plastic and an elastomer, a plurality of thermoplastics, or a plurality of elastomers are formed into a shaped item for an article (such as a dynamic seal, a static seal, a gasket, a pump diaphragm, a hose, or an o-ring), and the thermoplastic is then cross-lin |

Dynamic vulcanization with fluorocarbon processing aids |
November 11, 2008 |
| A curable fluorocarbon elastomer is dynamically cured in the presence of a major amount of a non-curing thermoplastic material and a minor amount of a second fluorocarbon elastomer that does not cure under the dynamic vulcanization conditions. The non-curing elastomer is preferably prese |

High temperature elastomers with low hydrocarbon vapor permeability |
March 25, 2008 |
| An elastomer blend is made by admixing fluoroelastomer and fluorinated silicone polymer (with optional filler and/or conductive particulate) into a polymeric admixture in weight ratios to provide a low vaporous hydrocarbon permeation rate and high thermal strain value in thermally ro |

Bimodal compounds having an elastomeric moiety |
March 11, 2008 |
| A bi-modal compound is provided having an elastomeric moiety and a second moiety derived from any of a metal, a ceramic, and thermoplastic. At least one free radical site is generated (preferably with electron beam radiation) on an elastomer molecule to provide the elastomeric moiety; |

Water resistant encoding material |
March 4, 2008 |
| A cured magnetizable admixture of elastomeric thermoplastic, dispersed magnetizable particulate, and optional dispersed hydrophobic material (such as ethylene acrylic monomer rubber or ethylene-vinyl acetate copolymer) provides elastic elongation of not less than about 50 percent at |

Dynamic vulcanization of polyurethane elastomeric material in the presence of thermoplastics |
December 19, 2006 |
| A thermoplastically processable cured rubber composition comprises a crosslinked or cured urethane polymer dispersed in a matrix made of a thermoplastic polymeric material. In one aspect, the matrix forms a continuous phase and the crosslinked urethane polymer is in the form of parti |

Reduced load gasket |
February 28, 2006 |
| A gasket is adapted to seal between a first member and a second member, and includes a first portion a second portion. The first portion includes a first elastomeric seal portion adapted to be in sealing engagement with the first member. The first portion may also include a clip or a coi |
