Simple introduction (product features)
1)Good liquidity
2)Low thermal conductivity
3)Rapid demoulding
4)The pore in the core of the foam is very less.
General description
Blend Polyol ZHD-8001 is a compounded polyether polyol developed for refrigerators and freezers. It is developed to be used with mixture of cyclopentne,iso pen tane and HFC-245fa as blowing agent. It contains polyether polyol, silicone surfactant, catalysts and water.
It does not contain any physical blowing agent, therefore the addition will be done before foaming the product.

Preparation
Before using,this polyol has to be mixed very well.
STORAGE OF MATERIALS
The materials are sensitive to humidity and partially used drums should be tightly sealed to
prevent the ingress of moisture.
ZHD-8001 (Polyol Blend)
The Polyol blend has a shelf life of three months from date of manufacture when stored indoors
at temperatures of 20-30°C. The Polyol blend should be thoroughly mixed before use.
ZHD-8001 (Isocyanate)
The Isocyanate has a shelf life of one year from date of manufacture when stored indoors at
temperatures of 20-30°C. Avoid storage temperatures of below 0°C (as some crystallization
may occur) or above 50°C (as formation of insoluble so lids may occur).
SAFTY PRECAUTIONS
Direct contact with ZHD-8001 can lead to moderate eye irritation and mild skin irritation, which can cause skin allergies. Repeated inhalation of high concentration of volatile gas will cause respiratory allergy, and should be treated immediately. Anti- inflammatory and anti-allergic treatment measures should be taken. Please be careful in the operation to prevent contact with the skin and splash into the eye, please wear the necessary protective equipment (gloves, protective goggles, working clothes, etc.). Once splashed on the skin or the eye, rinse with water immediately for at least 15 minutes, and the skin is washed with soapy water. Please seek medical treatment immediately after swallowed.
