Shanghai Daoqin Plastics Co., Ltd.

polyvinyl chloride (PVC) （Polyvinyl Chloride）PVC is types in day active in very Common plastics material, according to different manufacturing methods and processing conditions, PVC main/primary can separation is hard 质PVC and soft 质PVC两 types.

hard 质PVC hardness very high, tool has excellent heat resistant property, electrical insulation property and chemical resistant property and other, by widely used in various construction material, industrial products, electrical appliances outer housing/shell, automotive plastics and other field/area; soft 质PVC则 tool has relatively good flexibility property and can property, used for manufacturing soft tube/pipe, sheet/plate, electrical cable, use film, packaging film, tool, day use product and other product.

无论 is hard 质PVC also is soft 质PVC, it upper color need use material or material color agent, commonly used PVC color agent main/primary various has machine material, machine material and solvent agent material and other. need attention/notes is, due to hard 质PVC and soft 质PVC material property different, therefore in it color agent selection upper is has difference, in selection color agent 时应该 according to specific PVC材 material type type and upper color requirements most combined 适 颜 material type type or material.

for/regarding hard 质PVC, usually need selection tool has relatively good heat resistant property, chemical resistant property and good light stabilization property color agent, main/primary recommendation high temperature resistance property can good solvent agent material color is 主（注: solvent agent material this very more 人会联想 to use solvent agent solvent understanding rear color, upper solvent agent material in used for large more plastics color is high temperature solvent understanding color, is use solvent agent solvent understanding ）, hard 质PVC也 can use high resistant temperature has machine material or machine material color.

for/regarding soft 质PVC color, main/primary is tool has good heat resistant property and resistant property has machine material and machine material is 主, 如酞菁蓝, 酞菁绿, oxidation iron 黄, and other, by widely used in soft 质PVC color in; solvent agent material suitable for soft 质PVC color, this main/primary is is soft 质PVC increase agent content relatively high, material property non strong/high, material through increase agent to PVC products surface, especially easy 发生迁移 phenomenon.

总之, hard 质PVC and soft 质PVC color agent selection need according to specific application demand and material property 质 进行 combined 理搭配, different PVC材 material need use different type type material or material, in color process in, need attention/notes color agent suitable property and concentrated degree, effect/influence color and material property can.
