PETROLÁTEX NX 43 TECHNICAL DATA

 PRODUCT DESCRIPTION

PETROLÁTEX NX 43 is an aqueous emulsion of PETROLÁTEX NX 43 is modified with the a Carboxylated Butadiene-Acrylonitrile homogeneous introduction of specific carboxyl copolymer produced by hot emulsion groups which promote the selfcrosslinking of the polymerization using an anionic soap and polymer chains backbone. stabilized with a nonstaining antioxidant. The PETROLÁTEX NX-43 is a protein free latex so glass transition temperature of the polymer (Tg the risk of alergenic reactions is minimized . DSC) is around -24ºC (8ºF).

 CHARACTERISTICS The main characteristics of PETROLÁTEX NX-43  Good film formation and flexibility . are :  The polymer presents high resistance to  Excelent mechanical stability (stable during mineral oils, greases , fuels and solvents. pumping and other high shear operations).  Good mechanical properties, mainly fatigue  Coagulum free product. resistance. Excelent chemical stability to wide pH   Good heat resistance and low permeability variations . to gases. Excelent compound stability.   Production of odor free articles.  Protein free.

 TYPICAL APPLICATIONS  The main applications of PETROLÁTEX NX 43  The latex may be coagulated using aqueous are: solutions of CaCl2 , MgCl2 , Al2(SO4) 3 or  Articles produced by dipping process: synthetic polyelectrolytes. The use of mineral acids alone doesn´t coagulate the supported gloves resistant to solvents , latex. greases and fuels. The viscosity may be increased by adding  For agglomeration of cellulose and asbestos  conventional thickeners such as CMC or in the sealing articles production . polyacrylates.  For impregnation of oil resistant carpets .  In the dipping processes when it is desired a  In the production of sealants in contact with fine control of compound rheology we oils and aerossol. recommend the use of PETROFLEX SX-700  As a binder for non-woven fabrics and all thickener which enables the compound to kinds of fibres. have behaviour as a Bingham fluid.

PETROLÁTEX NX 43 is supplied in 200 liters drums . It may also be supplied in bulk by road tankers or in non-returnable 1,000 liters containers. PETROLÁTEX NX 43 should be stored in dry even conditions at temperatures between 10 and 30ºC and away from direct sunlight . When stored in tanks , vertical cylinder types are recommended. The tanks may be stainless steel , fiberglass or epoxy lined carbon steel . The tanks should be protected from normal weather conditions and out from direct sunlight to avoid over heating. To avoid bacteria accumulation, a complete cleaning of the tubing and tanks 2 to 3 times a year is recommended. Two sterilizations per year of the tanks, pumps and lines are recommended. The latex should be stirred slowly 15 to 20 minutes daily .

If the above conditions are followed PETROFLEX warranties the product for six months from the production date.
