Advantages of color masterbatch

Masterbatch is a new type dedicated colorant for polymer materials, its tinctorial strength is higher than pigments themselves. Using masterbatch in the manufacturing process can simplify the production process and can complete coloring and product processing all at once. It also maintains a clean operating environment and saves time and materials. In the production of finished products, masterbatch can improve the dispersion and tinctorial strength of pigments in the product, using the same plastic masterbatch with plastic can be more compatible and well dispersed in plastic products, thus improves product quality. In addition, comparing with the direct use of colors, using color masterbatch can guarantee the stability and consistency of product color.

Plastic classification

Plastic is a polymer material, the shape of the molecule can be divided into two kinds: line and mesh. In general, plastic materials can be divided into two categories of "thermoplastics" and "thermosetting plastics". Thermoplastics is granular at normal temperature, it can be melted by heating to promote formation into a deformable state for shaping. After the temperature cools down, the shape of the material itself can be maintained the same as when it was heated. If reheated again, then it will become to melted state, therefore, this plasticity material can be reheated repeatedly and its solidification can form repeatedly, so it can be reused. Thermosetting plastic is generally powder or granular, after heating to a certain temperature it becomes a solid, even continueous heating after solidification can not change its state, therefore, thermosetting plastics can not be molded repeatedly by reheating so it can not be reused. However, mechanical properties, heat-pressure resistance and corrosion resistance etc. of thermosetting plastic are all superior than thermoplastics.

  Product certification

The company has passed ISO 9001-2008 quality management system certification, establishing standardized production processes in accordance with the spirit of ISO,it can strictly control every production process and produce stable and high quality products with comprehensive quality assurance on design, development, production, installation and services.

  Testing and certification

Our products must meet all international testing, all products are sent to SGS tests, it is also available in accordance with customer demand to send products to the relevant detection units for testings, such as the EU RoHS electronic Restriction of Hazardous Substances (RoHS) detection, the U.S. Food and Drug Administration (FDA) detection etc., all products conform with environmental and safety regulations. * To learn more about test content, please contact us*


Societe Generale de Surveillance S.A. (SGS S.A. in abbreviation ) is a multinational group and headquartered in Geneva, Switzerland, which specializes in inspection, verification, testing and certification services. HAWYNG products have passed the international certification testing of SGS , it ensures product quality, safety and more in line with international and local regulations and standards.

It is responsible for national medicines, food, biological products, cosmetics, veterinary drugs, medical devices and diagnostic supplies management. HAWYNG products have passed FDA certification and products comply with relevant safety regulations.

RoHS( Restriction of the use of certain hazardous substances in electrical and electronic equipment)

The EU implemented RoHS in July 1, 2006, it stipulated that each single material used in electrical and electronic products must comply with the requirements. All production lines and raw materials of electrical and electronic products may possibly contain lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+) , polybrominated diphenyl ethers (PBDE), or polybrominated biphenyls (PBB); six kinds of hazardous substances. If it is found to be detect false or any of the six kinds of hazardous substances is over-limited, not only will it be punished by heavy fines, but it also will be blacklisted and reported to not be imported and sold throughout Europe. Products include mainly: white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, and water heaters, etc., black goods, such as audio products, video products, DVD, CD, TV receivers, IT products, digital products, communications products, etc.; electric tools, electric and electronic toys, medical electrical equipment and other electrical and electronic products.
