Product Description
4A zeolite molecular sieve powder is widely used in the productionof polyurethane polymers, can not change its physical and chemical properties of the product under the condition of adsorption effect on the quality of the products, the impurities such as water. Can also be added to the process of production of specific polymer or coating as a selective adsorbent, used to generate suctionepiphytic process of CO2, H2S and other gases. Some of the molecular sieve powder can also be applied to the hollow glass composite rubber strips do drier, or used as a catalyst carrier.
