Product Description

Nature Description

Hydroxyl value (mgKOH/g)54.5-57.5 acid value (mgKOH/g)≤ 0.05 moisture (%)≤ 0.05 PH(ph)5-7 unsaturated value (mol/kg)≤ 0.01 viscosity (mPa · s/25℃)400-700 chromaticity (APHA)≤ 20 functionality 3 minutes 3000

Product Applications

Low unsaturation 3000 molecular weight polypropylene oxide ether triol can be used in various polyurethane waterproof series products, which can effectively increase the tensile strength of polyurethane products. It cannot be used in the preparation of soft polyurethane foam, which may lead to foam heartburn.

Security

Storage conditions： When transporting MN-3050DF, it should be strictly protected against rain and dirt, and be careful to handle it to prevent leakage caused by collision with hard objects. When storing MN-3050DF, it should be stored at room temperature in a ventilated and dry warehouse to avoid being in a humid environment, and the storage temperature should be kept below 50℃, so as to avoid sun exposure, away from water sources, heat source. Or sealed storage in containers made of steel, aluminum, polyethylene or polypropylene. To prevent moisture absorption and oxidation, it is recommended to fill the containers with nitrogen. If the storage temperature is higher than 60℃, the product quality will decrease. Short-term heating or cooling has little effect on the quality of the product, but attention should be paid to the obvious increase in viscosity when the product is at a lower temperature, this situation may bring some difficulties to the production and processing process.
