Product Description
3A molecular sieve activated powder is made by high-temperature roasting and activation of molecular sieve raw powder. Because the molecular sieve raw powder loses most of its moisture during the high-temperature roasting process, the molecular sieve activated powder has a strong adsorption capacity, and has good dispersibility and rapid adsorption capacity. It is often used directly in production as an adsorbent with selective adsorption properties, which can effectively remove trace moisture and other impurities in the material, avoid bubbles, and extend the service life of the material.
3A molecular sieve activated powder is widely used in the production of polymers such as polyurethane. It can adsorb impurities such as moisture that affect product quality without changing the physical and chemical properties of the product itself.
