Overview
PU polyurethane specific molecular sieve activated powder is made by adding stabilizers or suspending agents to polymer adsorbent raw powder and high-temperature calcination. Due to the loss of most of the moisture in the polymer adsorbent raw powder during high-temperature calcination, zeolite powder has strong activity and can be directly used as an adsorbent with selective adsorption in production.
Product Details
1) Product Introduction
PU polyurethane specific molecular sieve activation powderIt is made by adding stabilizers or suspending agents to polymer adsorbent raw powder through high-temperature calcination. Due to the loss of most of the moisture in the polymer adsorbent raw powder during high-temperature calcination, zeolite powder has strong activity and can be directly used as an adsorbent with selective adsorption in production.
A) Used in polyurethane products (coatings, adhesives, sealants), it can adsorb impurities such as moisture that affect product quality without changing the physical and chemical properties of the product itself.
B) In specific polymers or coatings, it is used as a selective adsorbent to adsorb the substances generated during the growth processCO2TheH2SWaiting for gas.
C） Deep drying of pigments and solvents.
D) Adhesives and sealants.
