Water-blowned PU system
JDPU 303 water foaming system for spray-applied
PUR foam plastic
The JDPU303 polyol composition is mainly used to manufacture
water-blown spraying foam .It has been widely used in the surface
spraying of automotives, and it also shows excellent performance
in applications such as waterproof, heat-preserving, corrosion-resistance
of buildings, automotives, as well as pipelines.
Features
* Good fluidity and storage stability.
* Foam plastics thereby have the character of high curing speed,
excellent adhesion, low thermal conductivity and good dimensional
stability.
Usage
* thermal insulation material in automotive interior trim system
* piping thermal insulation
* building industry
* household appliance
