Xintao Activated Molecular Sieve Powder is the original molecular sieve powder after roasting activated at high temperature to remove water, with excellent dispersion and strong adsorption activity.
Trace water is an important issue in the production and preparation of Polyurethane (PU) products. Trace water in polyols react with isocyanate to form carbon dioxide, resulting in foaming. At the same time, a large amount of heat is released, resulting in a shorter service life.
XINTAO activated molecular sieve powder added to polyurethane, Adhesive, Paint, Rubber and other products system, can be effective selective adsorption of trace water, inhibit the occurrence of side reactions, so as to reduce the bubble generation and extend the purpose of application period.
Chemical Principles: RHCO+H2O–RNH2+CO2
In some special area like painting, coating, raw materials, solvents and additives, etc. trace moisture can cause adverse effects, such as in zinc metal or coating, the existence of trace moisture will react with lively metallic pigment of zinc, aluminum and other generate hydrogen gas, will cause the tank pressure is too high, even in extreme circumstances cause leakage. XINTAO activated molecular sieve powder can effectively adsorb trace water in the system, inhibit the formation of hydrogen.
Activated Molecular Sieves Powder From Xintao Factory
Activated molecular sieve powder manufactured by Xintao factory has excellent chemical stability, activated molecular sieve powder itself will not react with the use of the system.
XINTAO is a trusted global supplier of Activated Molecular Sieve Powder. Feel free to send an inquiry to get the latest price, if you would like to buy in bulk.
