By Introducing carboxylic acid groups to the polymer backbone of sheet NBR ( nitrile butadiene rubber). Material Reference. Carboxylated Nitrile Rubber ( XNBR). BK Chemical Definition Carboxylated Nitrile RRP Compound Number Category 30000 Series ♦ Physical & Mechanical Properties Durometer 000 – 3, Hardness Range 50 – 90 Shore A Tensile nbr Strength Range 1 500 PSI. carboxylated Trade names include Perbunan Nipol, Krynac Europrene. Description: Carboxylated Nitrile is Nitrile with a carboxyl group carboxylated added to the formulation. Acrylonitrile butadiene rubber ( NBR) usually shortened to nitrile is a unique elastomer. Nbr carboxylated nitrile rubber sheet. It can be produced by free- radical emulsion polymerization of butadiene with nbr 15 to 45 percent acylonitrile nbr either hot carboxylated ( hot rubber) or cold ( cold rubber) : Rubber compounding is a very broad elastomers sheet are mixed with various chemicals carboxylated , ingredients ( , carboxylated nbr since basic rubbers , technical field even with each other) to obtain desired physical properties.309 4 – Carboxylated Acrylonitrile Butadiene Rubber ( XNBR). Formulation used for the preparation. This is due to sheet Nitrile' s compatibility with most environments as well as it' s relative cost compared to other rubber materials. Special Rubber - Nipol ® NBR. Offered in 36 inch 48 inch wide rolls, it can also be slit carboxylated nbr nbr to width custom cut to your specifications. Preparation of filler dispersions are dealt in Sections 3. Nitrile rubber Buna- N, also known as carboxylated NBR, acrylonitrile butadiene rubber, is a synthetic rubber copolymer of acrylonitrile ( ACN) , butadiene. The chart below is intended to help in carboxylated the material selection nbr stage of designing rubber parts / products. Carboxylated nitrile ( XNBR) is polymerized with acrylonitrile butadiene but sheet also incorporates a third carboxyl- containing monomer into the polymer chain.
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. For assistance in identifying the appropriate polymer or material, or to develop and formulate an HNBR rubber compound to meet your specific application and performance requirements, please contact Rahco Rubber, Inc. XNBR - CaRBoXylated NitRile RuBBeR Technical Data Sheet XNBR Rubber is a speciality Nitrile ( NBR) rubber that has been modified with the addition of carboxyl groups.
nbr carboxylated nitrile rubber sheet
This results in vulcanization bonds that provide significantly increased strength, measured by improved tensile, tear, modulus and abrasion resistance versus standard nitrile. Nitrile rubber is known for excellent resistance to petroleum oils, mineral oils, vegetable oils, abrasion, many acids and water.
