Activated Molecular Sieve Powder
Activated Molecular Sieve Powder
Introduction & Specs
| Introduction | Molecular sieve activated powder is made by adding special additives to molecular sieve raw powder and roasting at high temperature. Because the molecular sieve raw powder loses most of its water content during the high-temperature roasting process, the molecular activated powder has strong activity and can be directly used in production as an adsorbent with selective adsorption, such as mixed dispersion adsorption with materials. It is an amorphous desiccant. It can absorb impurities such as water that affect product quality without changing the physical and chemical properties of the product itself. |
| Benefits | l Good dispersibility
l Fast adsorption speed l Strong activity l Reducing moisture, eliminating bubbles, improving material uniformity and strength |
| Applications | ü 2k-Polyurethane coatings and moldings
ü 1k-Polyurethane storage protection ü Polysulfide and silicone systems for storage protection of metallic pigment coatings ü Carriers for control release chemicals ü Processing aids for polymer production ü Desiccant for production of polymer desiccant materials ü Cosmetic additives ü Storage protection additives for highly hygroscopic goods ü Flame retardant additives ü Modification of chemical reactions by removing water as a by-product |
