Acrylonitrile-butadiene-styrene (ABS) resins are widely used in electrical appliances, toys, office equipment, sanitary ware and other applications. The coloring of the ABS resin is generally carried out by color mixing in a coloring chamber, or by mixing a primary color resin with a color master. In the past, end product manufacturers and processors such as injection molding shop processors had the experience that when using batch emulsion ABS resin, they encountered some coloring problems, including: 1) primary color resin background Inconsistent, even for the same level of product, the resin base color is very different between different batches; 2) Different primary color ABS resins have different yellow hue. Therefore, end product manufacturers receive different batches of ABS resin whether they are picked up from the same resin manufacturer (mentioned above), or obtain additional ABS resin from different manufacturers, which requires additional operations. Additional resources and costs.
For end product manufacturers that use primary color resin and color masterbatch for coloring, it is generally necessary to frequently use large amounts of pigment to mask the yellowish background color from ABS resins from different batches or grades. In addition, the thermal stability and light stability of ABS molded parts are also of concern to end product manufacturers. Since ABS is applied to different end products, there is a real need to improve the coloring efficiency of ABS resins. This article will explore the photostability and thermal stability of several ABS resins. This provides the end product manufacturer with the information to select the most suitable ABS material for the product, especially for the production of light colored parts.
