"PIR foam or polyisocyanurate foam,is made from base materials of polyisocyanate and
polyol,catalyst,fire retardant additive and environmentally
friendly foam agent.
Polyisocyanurate (PIR) foam is a closed cell regid foam that combines light weight and
strengh with exceptional thermal insulating qualities.the material
is available as sectional pipe covering,complete with a vapor
barrier jacket,as well as sections for fittings and board segments
for equipment and tanks."
For use on piping,fittings,equipment and tanks operating in the
temperature range of -196℃ to 110℃,Typical applicatons include:
Commercial and industrial pipe and fitting insulation on chilled
water,tank insulation and core material for panel construction (not
used in commercial building return air plenums).
1. High temperature capability: polyisocyanurate foam does not
soften or lose its strentgh at elevated temperatures within the
recommended use limits.
2. Excellent chemical resistant: most commercial solvents have no
effect on polyisocyanurate,therefore a wide range of adhesives and
coatings are suitable for bonding and finishing this insulation
3. Low thermal conductivity: factory pre-curing provides consistent
4. Easy insulation :light weight and easy to install on a variety
5. Good moisture resistance: for both liquid and water vapor.
6. Excellent dimension stability.
Store in a cool,dry,frost-free place. Normal storage conditions in
up to 25℃ should provide indefinite shelf life.
Size: all kinds of plates and shells;
