In the plastics industry, molecular sieve are widely used for deep dehumidification and drying of hygroscopic engineering plastics, such as PET, PA, PC, and ABS. This drying process is a critical pre-treatment step to ensure the quality and performance of the final plastic products.The core principl

Characteristics of 4A Molecular SievesThe pore diameter of 4A molecular sieve is approximately 4 Å (0.4 nm), which is the origin of its name "4A". This specific pore size determines that it can adsorb molecules of a certain size, but cannot adsorb molecules with a diameter larger than this size. Due

What is 3A Molecular Sieves

In the factory's air compression system, most factories have extremely high requirements for the quality of compressed air. The general pressure dew point is -70℃ or -40℃. Therefore, drying equipment - adsorption dryers are almost always used. The drying agents commonly employed are mainly two types
