4A Molecular Sieve & Activation Powder

3A/4A/5A/13X molecular sieve & activation powder has strong moisture absorption ability even under low temperature and low humidity rate. At the time, it still possesses certain moisture absorption under high temperature. Molecular sieve can be placed in a muffle furnace and backed at 1020℉ for 2 hours, then transferred to a drying cylinder and cooled to room temperature for use.
