Rigid polyurethane and polyisocyanurate (polyiso) foams create one of the world's most popular, energy-efficient and versatile insulations. These foams can significantly cut energy costs while making commercial and residential properties more efficient and comfortable.
Polyurethanes are an important component in major appliances that consumers use every day. The most common use for polyurethanes in major appliances is rigid foams for refrigerator and freezer thermal insulation systems. Rigid polyurethane foam is an essential and cost-effective material that can be used for meeting required energy ratings in consumer refrigerators and freezers. The good thermal insulating properties of rigid polyurethane foams result from the combination of a fine, closed-cell foam structure and cell gases that resist heat transfer.
SPC-1008 series formulated polyol is designed to be used with HCFC-141b or cyclopentane as the blowing agent. It is widely used for the manufacture of refrigerator or freezer. Excellent operationality and flowability are the main features when it reacts with isocyanates for the formulation. The manufactured foam has good density distribution, high compressive strength and excellent dimensional stability.

packaging
Polyurethane is easy to absorb water. Must be strictly sealed to prevent the escape of blowing agent and moisture enter.
Should be placed in a dark, dry, cool and well ventilated place, away from heat and prevent exposure.
The ideal storage temperature is 15-30℃. If the temperature is higher than 30℃, then shelf life cut short
Shelf Life: six months
Package: Polyol (A):220kg/iron drum
Isocyanate (B): 250kg/iron drum
