Desiccant is an absorptive substance used as a drying agent. It is also known as Defoaming Masterbatch. Desiccant is a material that will attract and chemically bind moisture. As an oxygen absorber is to air, a desiccant is to moisture. Moisture sorption by silica gel is an example of physical adsorption, and sorption by calcium oxide is an example of a chemical reaction. The common process for using desiccants is to place a predetermined quantity of activated desiccant into containers with products and seal the containers.
Desiccant is an additive which has a moisture absorptive capacity of not less than 28.5% by weight. The feature which distinguishes it from other is that it will absorb a much greater amount of water vapour at a very low relative humidity than any other materials. Desiccant is most effective where there is a need of low critical humidity and where there is a high concentration of water vapour is there.
We at Shivam Polychem desiccant masterbatch manufacturer have a high tech laboratory, where the end product are tested by making Film & and checking parameters of moisture. Our lab is equipped with spectrophotometer, Injection moulding machine, lab extruder, two-roll mill, hydraulic Compression Press etc. We are leading Supplier, Exporter and Manufacturer of Desiccant Masterbatch. We have more than 20 years of experience in desiccants manufacturing. Desiccant Masterbatches can reduced the need for pre-drying of materials, allow processors to use recyclate with high moisture content and extend the control of processing moisture sensitive polymers. Desiccant master batches can antithetical problems which develop during the processing of plastics due to the presence of moisture.
Desiccant Masterbatch may be used to add and mix with the recycle materials before the plastic molding processing, which make us carry out molding processing without the drying process, so it is user-friendly, and can improve the construction efficiency and reduce energy expenditure.
