If the small amount of water in plastic raw material is not eliminated, bubble or water wave will form on the product surface and they will have a deadly effect on product strength or appearance. However, some problems lie in the traditional process of applying electrothermal drying machine to eliminating water , such as extension of product processing time (it takes one drying equipment about 15 hours to dry one-ton raw material), loss of raw material weight, high consumption of electricity, increase of production cost, ect.

Optical Brightening Agents (OBA) or Fluorescent Whitening Agents (FWA) is added to many substrates to reduce yellowing, improve whiteness and enhance the brightness of the product. Optical whiteners function by absorbing ultraviolet radiation and re-emitting blue light. The emitted blue light will reduce the yellow color of the substrate and impart a pleasing whiter-than-white appearance. Optical brighteners give more intensity to some colors as well.

It was also known as ASVA ACTIVE. Plastic product including extrusion, injection and film process is made of plastic raw material melt with high temperature by extrusion molding equipments. The quality of plastic product is directly and closely related to the compaction and drawback rate for molding product. The moisture content in raw material will directly impact to the quality of plastic product. The moisture will become steam in the process of plastic product and lead to drawback with bubble, crackle, spot and hole in plastic product, so that it influence the mechanics property and appearance of plastic product.

WSC IRREVERSIBLY REACTS WITH THE MOISTURE WHEN IT IS IN THE PROCESS OF CONVERSION TO VAPOUR & GAS. IT CHEMICALLY BINDS WITH THE H2O MOLECULES TO FORM STABLE COMPOUNDS THAT REMAIN STABLE AT ALL PLASTIC PROCESSING TEMPERATURES.

Calcium carbonate filler masterbatch is made with super fine calcium carbonate and other high quality special additives based in LLDPE carrier by advanced twin-screw extruder machine. The filler MB is very popular with our many of our customers because of its and stable high quality and excellent performance in the development of plastic products industry.

Transparent Filler Masterbatch is a high quality filler masterbatch made of inorganic transparent powder and other special additives based in a Polyolefine ( PP, PE ) carrier. The transparent filler masterbatch can enhance stiffness and transparency, tensile strength, heat distortion temperature and rigidity, then improve the properties of finished products. It is mainly used in PP and PE plastic extrusion, injection, film blowing package material and medicine container.

Exposure to sunlight and some artificial lights can have adverse effects on the useful life of plastic products. UV radiation can break down the chemical bonds in a polymer. This process is called photodegradation. It ultimately causes cracking, chalking, color changes and the loss of physical properties.

ANTI STATIC ADDITIVES Antistatic agents can be added to polymers to minimize the natural tendency of most plastics to accumulate static charges. Antistatics are based mainly based on migratory additive systems, which can give fast and long term stable antistatic properties. Migratory additives rely upon the presence of atmospheric humidity to give optimum performance.

Polymeric materials are susceptible to oxidative degradation by the action of heart. Thermal degradation can occur during melt processing of the polymer, or during the service life of the finished component. This degradation can result in a reduction in aesthetics, physical and mechanical properties or even discoloration of the part.

PROCESSING AID ADDITIVE polymer processing aids are designed to improve the melt processability and handling of high molecular weight polymers. They can also give finished articles improved aesthetic properties by removing flow marks and die lines there by improving the parts gloss and clarity.
