2LBS 4A Molecular Sieve Activation Powder

4A Molecular Sieve Activation Powder-4A molecular sieve activation powder is one of synthetic silica aluminate powder. With the capacity of absorbing molecules with a diameter of no more than 0.42nm such as H2O, O2, N2, H2, CO, CO2, NH3, CH4, C2H4, C2H6 and so on. It has fast adsorption speed which can absorb moisture more than 24% of its own weight at 25℃，RH40% and can be used at the low temperature of -20℃. It has good dispersity and adsorption capacity. Fast Adsorption Speed, Recyclable-4A Molecular Sieve Activation Powder has strong moisture absorption capacity at low temperature and low humidity, while at high temperature, it still has a certain adsorption capacity and is dried at 550℃ can achieve regeneration. Wide Application-4A molecular sieve activation powder is used in the production of polyurethane and other polymers, which can absorb impurities such as water that affect product quality without changing the physical and chemical properties of the product itself. It can also
