Definition Polypropylene is a thermoplastic material resulting from the polymerization of the propylene by catalysts. Polypropylene may also be called Polypropene. Polypropylene is usually represented by PP. Comments Polypropylene belongs to the olefins family as a polyolefins together with the Polyethylene. The Polypropylene is a polymer produced from the propylene monomer by catalytic polymerization. Because of its balanced crystalline molecular structure, […]
Definition VFA stands for Vinylformamide or n-Vinylformamide. Vinylformamide may also be named n-ethenyl-formamide or SR-497 Comments After polymerization and subsequent hydrolysis N-Vinylformamide (VFA) introduces a primary amine into a polymer, which can be used for cationically charged polymers or crosslinking with e.g. epoxides. Vinylformamide (VFA) is an important feedstock for water soluble, cationic polymers. These materials […]
BASF to build butadiene extraction plant in Antwerp The butadiene is a monomer and used as an important chemical intermediate to produce elastomers and thermoplastics, such as synthetic rubbers, latex, acrylonitrile butadiene styrene copolymer and polyamide. The tire industry is the main consumers of butadiene. Other applications for butadiene include paper chemicals and plastics production. BASF is […]
Definition NBR stands for Nitrile Butadiene Rubber or Acrylonitrile Butadiene Rubber or Buna-N or Perbunan. NBR is a synthetic rubber which belongs to the family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1,2-butadiene and 1,3-butadiene) Comments NBR is produced in an emulsion polymerization system. The water, emulsifier/soap, monomers (butadiene and acrylonitrile), radical generating activator, and […]
Saudi Kayan, Sabic, Saudi Aramco, Dow, Sahara and Tasnee aligned to tender EPC Contract In January 2011, Saudi Kayan Petrochemical had signed a deal for equal partnership to build a new n-butanol (NBA) plant at Al Jubail Industrial City. The deal was signed between Saudi Kayan, Saudi Acrylic Acid Co (SAAC) and Sadara, the Saudi Aramco-Dow […]
Definition Polyethylene (PE) is a thermoplastic polymer consisting of long hydrocarbon chains. A molecule of polyethylene is nothing more than a long chain of carbon atoms, with two hydrogen atoms attached to each carbon atom. Polyethylene is produced from the polymerization of ethylene as monomer. Polyethylene may have different grade of density with different melting point temperatures […]
