Method for manufacturing sealing rings

Abstract: The method comprises taking textile or synthetic threads and impregnating the threads by passage in a bath of an elastomer or plastomer material. Thereafter a band is formed from the impregnated threads and shaped into a ring and moulded under pressure.

Microwave energy sensitizing concentrate

Abstract: A composition of matter suitable for sensitizing thermoplastic compositions to the heating effects of microwave energy in which the components of the composition are (1) an alcohol amine or derivative thereof; (2) a simple or polymeric alkylene glycol or derivative thereof; (3) silica; and (4) optionally, a plastomer that is a normally solid linear or radial teleblock copolymer derived from butadiene and styrene. A method for preparing this composition as a dry, free-flowing powder by preparing a liquid mixture of the polymeric alkylene glycol or derivative and the alcohol amine or derivative which mixture is then charged into a premixed combination of granulated plastomer, if used, and silica. A method for preparing flow molding compounds by admixing a non-polar thermoplastic with a sufficient amount of the sensitizer composition to provide microwave energy sensitivity. Subjecting the flow molding composition, in a mold, to microwave energy thereby producing a flow molded composition.

Patio slab - made of two plastomer layers with shredded types overlain by coloured layer with tyre granules

Abstract: Slabs for patios, garden paths etc. are made of shredded used rubber tyres which are embedded in plastics or other synthetic material. The top layer is made of a mixture of granules, made of used tyres and mixed with coloured plastics. The pref. sizes are 40 x 40 or 50 x 50 cm and 4 or 5 cm thickness. The new slabs are permeable to water so that rain pools cannot form. They are skidproof, elastic and easy to lay.
