A molecular sieve is a material with tiny, uniform pores that is used to adsorb gases and liquids. Unlike common filters, the molecular sieve operates on a molecular level. It only could adsorb molecules which are small enough to pass through the pores, such as water molecules. Because of this, the molecular sieve is usually used as a desiccant, which can adsorb water up to 22% of its own weight.
Molecular sieves often consist of aluminosilicate minerals, clays, zeolites, active carbons, synthetic compounds, etc. that have pores which small molecules can pass through. Usually, a 4 to 8 mesh sieve is ideal for gas phase applications, and a 8 to 12 mesh sieve is perfect for liquid phase applications. The powder forms of the 3A, 4A, 5A and 13X sieves are used in specialized applications.

pvc resin for blow molded bottles, pipes and tubes, molecular grade film, medical grade vinyl suspension resin. also sells off grade pvc resin for non critical end uses.
Raw materials list: polypropylene nonwovens, meltblown filter cloth, nose clip bar, and earrings Spunbond nonwoven prevents droplets, body fluids, etc. from entering the mouth and nose directly. The inner layer raw material of spunbond nonwoven absorbs moisture and is at the same time the last barrier between the virus and the respiratory tract. The meltblown nonwoven in the middle has an ultra-fine fiber structure that prevents viruses, which are even finer particles, from entering. In addition to the mechanical filtration of particles, the fibers can also adsorb even smaller particles through molecular gravity and electrostatic effects.
