RUBBER FOAM
DESCRIPTION:
Rubber foam using butyronitrile rubber and polyvinyl chloride (NBR, PVC) with best performance as main raw materials and other high quality auxiliary materials through special procedure foaming .This product is an closed cell elastic material, has such perfect performances as soft, anti-bending, cold-resistant, heat-resisting, fieblocking, water-proof, low thermal conductivity, shake-reduction and sound-absorption. It can be widely used for every kind of cold/ hot medium piping and containers in central control air condition, construction, chemical industry, medicine, light industry, textile process, metallurgy, boat, vehicle, electrical apparatus and other filds to reduce cold/thermal loicine, light industry, textile process, metallurgy, boat, vehicle, electrical apparatus and other filds to reduce cold/thermal loss. In addition, because this product is easy to be installed, has beautiful appearance and never has any pollution, therefore, it is a new generation high quality heat-insulating, and heatpreservation material. As this material has soft and anti-bending performances, so it can be used to make handlebar sleeves of bodybuilding apparatus, medical equipment, covers or shields for articles of daily necessities.
FEATURES:
Stronger fire performance
Better thermal insulation performance
Longer service life
Higher appearance and easier to maintain
