STH dioctyl phthalate for hromatogr. (3 ml)

Plasticizers are substances which enter in sostavpolimernykhmaterial for giving (or increases) elastichnostiya (or) plasticity during the processing and operation. Plasticizers facilitate dispersion of ingredients, reduce temperature of technology processing of compositions, improve frost resistance of polymers, but sometimes worsen their heat resistance. Some plasticizers can raise fire - the sacred and thermal stability of polymers.

General requirements to plasticizers: good compatibility with polymer, low volatility, lack of smell, chemical inertness, resistance to extraction from polymer liquid environments, for example oils, detergents.

The most widespread plasticizers: esters, for example dioctyl phthalate, dimethyl phthalate, dibutyl phthalate, dibutyl sebacate, dioctyladipate, dioctylsebacate, diisobutyl phthalate, three (2 ethylhexyl) phosphate, efiryftalevy and trimellitic acid, difficult efiryortofosforny acid. Also mineral and non - drying vegetable oils, epoxidized soybean oil, chlorinated paraffins, etc. are used.

The number of the plasticizer in composition — from 1 … 2 to 100% (from the mass of polymer).

The main consumer of plasticizers — the industry of plastic (about 70% of total production of plasticizers are spent for plastic compound production)

Plasticizers are widely used by production of nail varnishes.

Plasticizers are also surface - active additives which enter into construction solutions and concrete mixes (0,15 … 0,3% of the mass of knitting) for simplification of laying in form and decrease in water content. It improves the majority of characteristics of the hardened mix, and also allows to cut cement consumption, to reduce energy costs when vibrating concrete (the self - condensed mixes) or leveling of couplers (the bulk self - leveled mixes for floors).

Widely used plasticizer of this type — sulfite alcohol grain stillage. Later super - and hyper plasticizers with smaller dosages, and also the antifrosty, airinvolving and other useful properties have been created.
