The invention relates to an anti-vibration device (100), for example intended for a railroad application, comprising: a first frame (10), a second frame (20), a shock absorbing structure (30) for the vibrations, situated between the two frames (10, 20), and at least one fire barrier layer (40) at least partially covering the shock absorbing structure (30);
characterized in that said at least one fire barrier layer (40) is a polychloroprene-based elastomer including at least one fire retardance agent chosen from among alumina trihydrate or magnesium hydroxide.

The invention relates to a textile bonding composition comprising a salt of lignosulfonate, an aldehyde hardener thereof, and an elastomer latex. The lignosulfonate salt may be sodium, potassium, magnesium, ammonium, or calcium lignosulfonate. The invention also relates to the use of such a composition for imparting adhesion properties to a reinforcement textile, with regard to a rubber, a reinforcement textile, in particular yarn, cord or textile structure, at least partially coated and/or impregnated with this composition, and a part made of rubber or comprising a rubber, in which the rubber comprises at least one reinforcement textile, on the surface and/or integrated inside the rubber.

An adhesive composition is comprised of a film forming polymer, (ii) a lower crystallinity polynitroso compound, (e.g., poly-(1,4-phenylyenazine-N,N-dioxide)), (iii) a higher crystallinity polynitroso compound (e.g., poly-(1,4-phenylyenazine-N,N-dioxide)), and (iv) a carrier liquid. The composition is useful in bonding metal and rubber to make, for example, components to damp noise, vibration or harshness.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

The invention relates to an article having a single- or multi-layered main body having elastic properties, in particular an air spring bellows, a metal-rubber element or a vibration damper. In order to improve its flame retardant properties, the main body of the article consists of or contains at least one layer D constructed from a rubber mixture which is free from halogen-containing flame retardants and contains a first aluminum trihydrate (ATH_1) and at least one further aluminum trihydrate (ATH_2) and at least one amorphous silicic acid having spherical particle geometry, wherein the first aluminum trihydrate (ATH_1) and the further aluminum trihydrate (ATH_2) each have a different particle size.
