Introdution of Performance and Uses of DIDP
Diisodecyl phthalate (DIDP)
This product is a primary plasticizer with heat resistance
and good degradation resistance. With excellent volatility
resistance, ****electrical insulation and mechnical
performance, its flexibility becomes less as the increase
of temperature. Owing to its good heat-resistance, low
volatility and its electrical insulation, the product
is widely used in the production of heat-resisting （105 ）cable,
built-in decorating material for car and conveyer belt,etc.
If used in plastisol, it can present fine fluidity to
the paste and the viscosity has few changes in storage.
Also it can serve as plasticizer of synthetic rubber,
with no effect on the sulfuration of gross rubber.
