biological activity | Butyl benyl phthlate (BBP, 1, 2-bengenedatherosclerotic acid, butyl phenylmethyl ester) is a phthalate ester, is a toxic substance that may be used as a plasticizer. |
Use | used as plasticizer for polyvinyl chloride, Vinyl Chloride Copolymer, cellulose resin, natural and synthetic rubber mainly used as plasticizer. It has strong dissolution ability, good mutual solubility with polyvinyl chloride resin, vinyl acetate resin, polystyrene and nitrocellulose, Good pollution resistance, fast plasticizing speed and large filler capacity, resistant to water and oil extraction. It may be used as a primary plasticizer. Often with other plasticizers, for a large number of fillers in the plastic floor, decorative materials, corrugated board. The product is used for the manufacture of films, plates and pipes, and can obtain products with excellent transparency and smooth surface. It is also used for calendering foam artificial leather. |
