Impact modifiers, additive coloring effects

The effects of BPA-PC molecular weight dominate the properties of blends that contain this material. Modifications are also made by blending with other polymers and the use of additives to achieve specific effects. These additives may be UV stabilizers, thermal stabilizers, flame retardants, mold release agents, fillers, colorants, impact modifiers, etc. Blends are made with... 

A wide variety of additives and modifiers are incorporated into polymers and polymer blends to tailor specific properties. Unfortunately, these additives can also impact the colorability to the total resin system. Listed below are some common additives and modifiers used in polymers and a short discussion of their typical effect on colorability. 

Commercial plastics are invariably mixtures of one or more polymers blended with a variety of additives such as colorants, flame-retardants, biocides, etc., all tailored to achieve cost-effective performance for specific applications or processibility requirements. For example, flexible PVC for wire insulation contains one or more plasticizers, and poly (2,6-dimethyl-1,4-phenylene oxide) (PPO), an engineering plastic, is marketed in several grades which may contain varying amounts of lubricants, stabilizers, fillers etc., in addition to the high-impact PS (HIPS) which is added to PPO to modify impact properties and melt viscosity.
