Description

" or,is made from base materials of polyisocyanate and polyol,catalyst,fire retardant additive and environmentally friendly foam agent.

Polyisocyanurate () 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."

Uses

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).

Advantages

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 material.

3. Low thermal conductivity: factory pre-curing provides consistent physcial properties.

4. Easy insulation:light weight and easy to install on a variety of surfaces.

5. Good moisture resistance: for both liquid and water vapor.

6. Excellent dimension stability.

Packing

Packing: Carton

Storage

Store in a cool,dry,frost-free place. Normal storage conditions in up to 25℃ should provide indefinite shelf life.
