Liquid mixing processes are provided for producing an elastomeric composition as a function of a selected elastomeric composition recipe. A system (10) is also provided for the production of an elastomeric composition according to the disclosed liquid mixing processes.

The present invention concerns an elastic fibrous material, based on a fiber network, also including an elastomeric component, which material has been formed into a flat structure with two surfaces. Further, the invention concerns a method of manufacturing said elastic fibrous material by forming a fiber network, containing an elastic polymer, foaming the fiber network, adding it into one or more layers on a support, followed by curing.

The present disclosure relates to synthetic polyisoprene elastomeric articles including: one or more cured blend compositions of pre-vulcanized synthetic polyisoprene particles and non-prevulcanized synthetic polyisoprene particles, wherein the pre-vulcanized synthetic polyisoprene particles and the non-prevulcanized synthetic polyisoprene particles are bonded by mono-sulfidic and/or di-sulfidic, and poly-sulfidic crosslinks, wherein the poly-sulfidic crosslinks are present in an amount of 60 to 79 percent of the total amount of crosslinks in the cured blend composition. Methods of making synthetic polyisoprene elastomeric articles such as gloves or condoms is also disclosed.

A stabilizer adhesive bearing for a vehicle stabilizer may comprise an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer. The resilient inner contour of the annular sleeve may comprise on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume. The three-dimensionally structured surface has a maximum roughness depth (R.sub.max) greater than 45 m and a core roughness depth (R.sub.K) of at least 65% relative to the maximum roughness depth (R.sub.max) of the three-dimensionally structured surface. The maximum roughness depth (R.sub.max) is a total of the reduced tip height (R.sub.pk) and the reduced groove depth (R.sub.vk). Further, the reduced tip height (R.sub.pk), the reduced groove depth (R.sub.vk), and the core roughness depth (R.sub.K) may be determined in accordance with EN ISO 13565-2: December 1997.

Disclosed is a latex composition for dip-molding and a dip-molded article produced therefrom. More specifically, a dip-molded article having slow syneresis, less stickiness and superior tensile strength is produce by dip-molding of a carbonic acid-modified nitrile-based copolymer latex having increased molecular stability due to the combined use of alkenylsuccinate, which is an emulsifier crosslinkable with the latex and having a flexible molecular structure.

Provided is: A glove dipping composition including, at least: an elastomer that contains a (meth)acrylonitrile-derived structural unit, an unsaturated carboxylic acid-derived structural unit and a butadiene-derived structural unit in a polymer main chain; a polycarbodiimide; zinc oxide and/or an aluminum complex; water; and at least one pH modifier selected from an ammonium compound and an amine compound, in which glove dipping composition the polycarbodiimide includes at least one polycarbodiimide containing a hydrophilic segment in its molecular structure and has an average polymerization degree of 3.8 or higher and a carbodiimide equivalent of 260 to 600; the polycarbodiimide is added in an amount of 0.1 to 4.0% by weight and zinc oxide and/or the aluminum complex is/are added in an amount of 0.1 to 5.6% by weight with respect to the total solid content of the glove dipping composition; and the glove dipping composition has a pH of 9.0 to 11.5.

A one-piece rubber boot shell is created by a process comprising the steps of disposing rubber pieces within a cavity of a molding machine, the molding machine having an upper mold, a lower mold, and a last suspended between the upper mold and the lower mold. The process includes closing the molding machine by moving at least one of the upper mold, the lower mold, and the last toward each other so that they are adjacent each other, heating the rubber pieces to flow within the cavity and around the last to form a one-piece rubber boot shell, and opening the molding machine by moving at least one of the upper mold, the lower mold, and the last away from each other so that they are spaced apart from each. The one-piece rubber boot shell is then removed from the last.
