PETROFLEX NBR 3300 DHP Series TECHNICAL DATA

 PRODUCT DESCRIPTION PETROFLEX NBR 3300 DHP Series Elastomers are products series presents a particularly high level of quality and butadiene-acrylonitrile copolymers with medium bound properties, exibiting better processing/mixing characteristics acrylonitrile content (33%) produced by cold emulsion and reduced mold fouling than conventional nitrile rubbers. polymerization under carefully controlled temperature. These PETROFLEX NBR 3300 DHP Series Elastomers are employed in oil and solvents chemical resistance goods.

 TYPICAL APPLICATIONS PETROFLEX NBR 3300 DHP Series Elastomers is recommended for all kind of techincal goods including gaskets specially recommended for cellular hoses and tubes, and and retainers, seals (static seals, pipeline seals), “O” rings rubber formulations with great amount of fillers. Is also (shaft seals, grooved rings and V-type seals) etc that demands better processing/mixing characteristics and properties.

 PROCESSING CHARACTERISTICS PETROFLEX NBR 3300 DHP Series Elastomers can be prepared and processed on conventional machinery used in the rubber industry (mixing mills or internal mixers). The processing of NBR compounds is similar to that of correspondingly SBR or natural rubber compounds. Nevertheless, some differences should be noted. With NBR there is very little viscosity reduction during either the preparation or further processing. The processing properties are decided mainly by the NBR type used for the compound, but depend upon the choice of fillers, plasticizers and processing aids. The curative systems also may influence the processing behaviour.
