Dibutyl phthalate/DBP 99% Industrial Grade Colorless transparent oily liquid

Dibutyl phthalate, is an organic compound, chemical formula C16H22O4, can be used as polyvinyl acetate, alkyd resin, nitrocellulose, ethyl cellulose and neoprene rubber, nitrile rubber plasticizer.

Dibutyl phthalate (DBP) is the most commonly used plasticizer of PVC, which could make the products have good softness but poor durability. Stability, flexability, adhesion and water resistance are better than other plasticizers. Dibutyl phthalate is commonly used as an adhesive and additive in printing inks. Soluble in many organic solvents, such as alcohol, ether and benzene. DBP is also used as an ectopicide.

Dibutyl phthalate (DBP) is a kind of excellent plasticizer, which is the largest kind of plasticizer in output and consumption. For a variety of resins have very good solubility, used as the main plasticizer, with light color, low toxicity, good electrical performance, low volatility, small odor and low temperature resistance.

However, some studies believe that dibutyl phthalate is a kind of environmental endocrine disruptor, which has a significant interference effect on animal estrogen. Some researchers believe that high doses of phthalates in women increase the risk of breast cancer and may harm the development of their reproductive systems in the future to give birth to boys.

This product is a plasticizer, non-toxic. Mainly used as polyvinyl chloride plasticizer, can make products have good softness. Because of its relatively low price and good processing, it is widely used in China, almost as much as DOP. However, its volatility and water extraction ability are large, so the durability of the product is poor, and its use should be gradually limited. This product is an excellent plasticizer of nitrocellulose with strong gelation ability. Used for nitrocellulose coating, has excellent softening effect, stability, adhesion. This product can also be used as polyvinyl acetate, alkyd resin, ethyl cellulose, natural and synthetic rubber, as well as plexiglass and plasticizer.
