  • Patent number: 8226868
    Abstract: A device for preparing a flat profiled element from an elastomeric thermoplastic gel includes: an extruder with at least one feed and a discharge; an extruder die having section configured to be suitable for a profile of the flat profiled element; a liquid cooling bath with a free surface for receiving and cooling the flat profiled element as the flat profiled element is discharged from the extruder die; and a flat moving support for receiving the flat profiled element. The free surface of the liquid cooling bath is arranged in an immediate vicinity of an outlet of the extruder die. Additionally, an angle of inclination of a plane of the extruder die to a horizontal plane is between 20 and 70 degrees.

  • Publication number: 20120149822
    Abstract: An inflatable object is equipped with a layer for sealing in an inflation gas. The layer is formed of an elastomeric composition that includes a predominant elastomer by weight, a block thermoplastic elastomer, and a lamellar filler. The block thermoplastic elastomer includes a polyisobutylene block with a number-average molecular mass ranging from 25,000 to 350,000 g/mol and a glass transition temperature of less than or equal to ?20° C., and, at at least one end of the polyisobutylene block, a thermoplastic block made from at least a polymerized monomer other than a stirene monomer, the polymerized monomer having a glass transition temperature greater than or equal to 100° C. The lamellar filler has an equivalent diameter (Dv (0.5)) of between 15 and 60 micrometers and an aspect ratio (F) of greater than 65.
