Electrical properties. Insulation or jacket pesticide colorants Which polyvinyl chloride, polyethylene and other plastics for a large number of wire and cable sales is good, these applications requires the colorant has good electrical insulation properties, the coloring agent is added after some can cause electrical insulating properties Which decreased pesticide colorant large scale, generally leading to the main electrical insulation performance is due to the pigment surface residual electrolyte, rather than the pigment colorant pesticide itself, so some pigments containing soluble salts do not apply to the wire cables and other plastic products, coloring, usually good electrical properties of carbon black, titanium dioxide, chrome yellow, phthalocyanine blue and other pigments. Animal itself can not synthesize pigment. The study also found that only oxygen-containing functional groups (such as hydroxyl, acyl, keto, etc.) carotenoids (carotenoids) classes in the livestock, poultry, aquatic products only within the coloring effect. Pesticide colorant products, Weifang Fuyuan (certified), pesticide colorant provided by Environmental Science and Technology Co., Ltd. Weifang Fuyuan.
