A structure for and method of producing large diameter seal rings. Preferred embodiments of the present invention make use of a co-extruded "support" layer of a polymer showing better weld quality and strength. The use of a co-extruded support polymer bonded to the functional polymer can be used to improve the strength of the entire weld, including the weld of functional polymer layer.

The invention relates to a gasket for a battery, wherein the gasket is made from a polyamide composition comprising at least 70 wt.% of a polyamide X.Y, wherein X and Y represent respective residues from the condensation of an aliphatic diamine comprising 4 to 18 carbon atoms, and preferably 5 to 12 carbon atoms, with a (cyclo)aliphatic diacid comprising 10 to 18 carbon atoms, and wherein the polyamide composition further comprises a nucleating agent.
摘要:
A weatherstrip assembly for a vehicle. The assembly includes a body having a base and first and second legs which define a channel. The body includes an interior base surface, a first interior leg surface, and a second interior leg surface disposed within the channel. The assembly includes at least one sealing lip having an abutment surface and a wearstrip disposed along at least one of the interior base surface, the first and second interior leg surfaces, and the abutment surface and formed of a thermoplastic polyethylene material. The wearstrip has a plurality of alternating wear sections and gaps that define a series of alternating semi-rigid and flexible sections, respectively, with each wear section having first and second surfaces. The first surface of one of the wear sections and the second surface of an adjacent wear section face each other to define the gap.

Abstract: A sealing material which does not sag after application and shows excellent sealing performance even under severe high-temperature conditions. Even when used with foaming, the sealing material can form satisfactory closed cells therein. Also provided is a method of foaming application of the sealing material. The sealing material is characterized by comprising an ultraviolet-curable ingredient and an ultraviolet-polymerizable initiator, the content of any thermoplastic elastomer not curable with ultraviolet in the material being 5 wt.% or lower. It is further characterized in that the ultraviolet-curable ingredient comprises an acrylate which gives an ultraviolet-cured polymer having a glass transition temperature and a weight-average molecular weight in respective certain ranges, and that the sealing material has a melt viscosity at 120°C in a certain range. The method of sealing-material foaming application is characterized by thermally melting the sealing material, incorporating nitrogen gas into the molten sealing material at a given elevated pressure, ejecting the mixture in the air at a given pressure and applying it to an area needing sealing while foaming the mixture to thereby form a sealing foam, and curing the foam with ultraviolet.

A method is provided for manufacturing an upper reveal that conforms to a curved portion of a window opening of a motor vehicle door frame. The upper reveal is formed from TPV and a carrier. The method includes the steps of: co-extruding the TPV with the carrier; curing the TPV to form the upper reveal; heating the upper reveal to a temperature greater than a heat deformation temperature of the TPV; and bending the upper reveal to conform to the curved portion of the window opening of the motor vehicle door frame.
