Product details
NITRIAL RUBBER SAI INSULATION INDIA IS A LEADING, SUPPLYING, MANUFACTURING, DEALERS, DISTRUBUTERS INSULATION MATERIALS INSTALETION, CONTRACTORE, THERMAL ACCOSTIC, HOT, COLD INSULATION WORK AND SUPPLY, There are five general types of NBR. Cold NBR, is polymerized at temperatures from 5° to 15°C, yielding more-linear polymer chains. Hot NBR, is manufactured at temperatures ranging from 30° to 40°C, which yields highly branched polymers. The branching supports a strong bond and improved hot tear strength compared to cold NBR. Hot NBR is excellent for compression molded products, extruded shapes and sponge products. Crosslinked Hot NBR, has an added di-functional monomer that provides the rubber with increased strength for molding and shape retention for extruded products. These NBR's are used as additives to PVC's to increase impact resistance and flexibility. Carboxylated Nitrile (XNBR), is used when increased strength is required for an application. It is manufactured by the addition of carboxylic acid groups to the NBR polymers' backbone. Bound Antioxidant NBR, has antioxidants polymerized into the polymer chain. The addition of antioxidants protects the rubber during prolonged fluid exposure or in mixed fluid and air exposure in demanding environments.
