PVC1. Some metal ions in the pigment will cause the thermal oxygen decomposition of PVC resin as Figure 1.
The determination method is the color phase change when the pigment polyethylene is heated to 180 C. Because of the metal ions in the pigment, the decomposition of PVC is accelerated and the color phase changes. At the same time, also noted that the same color with red lake can make PVC have different, such as calcium, manganese is small color difference; color difference, this is because manganese metal promoted PVC dehydrochlorination induced.
Sulphide coloring agents (such as cadmium red and yellow, etc.) are used for coloring PVC and may be decomposed by colorants. The colorant not with lead stabilizer mix, in order to avoid generating black lead sulfide.
2. The influence of pigment on the electrical insulation of PVC
As polyvinyl chloride and polyethylene, as cable materials, the electrical properties of coloring should be considered. In particular, polyvinyl chloride is more poor in its insulation than polyethylene, so the effect of pigment is greater. It shows that the selection of inorganic pigment coloring PVC is better for its electrical insulation than that of organic pigment (except for furnace black and anatase titanium dioxide).
Mobility
Mobility occurs only in plasticized PVC products, and in the use of dyes or organic pigments. The transfer is part of the existing in the surrounding solvent soluble dye or pigment, the plasticizer penetrated into the surface of PVC products, the dissolved dye (pigment) particles were also brought to the products on the surface, thus lead to contact bleeding, bleeding or a solvent. [5]
Another problem is "Scaling". When colorants are dyed, they are freed from the system due to their poor compatibility or incompatibility. They are deposited on the surface of the processing equipment, such as the inner wall of the extruder and the inner wall of the die hole.

classification
Anti static PA, conductive PA, fiber fireproof PA, fireproof PA, anti ultraviolet weather resistance PA, high temperature extrusion grade PA.
Conductive nylon 66: it has good wear resistance, heat resistance, oil resistance and chemical resistance. It also greatly reduces the water absorption and shrinkage of raw materials, and has excellent dimensional stability and excellent mechanical strength. It can meet the requirements of electrostatic discharge and electrostatic discharge (ESD) protection. These special modified materials are specially prepared and are suitable for the range of surface resistance from 100 to 1012 ohm / square (ohms/sq), which can be used for injection and extrusion molding. There are many advantages over metal and coating: the parts are lighter, easier to handle, and the cost of transportation is low. They are easy to assemble, have low manufacturing costs, and are less likely to be dented, cut and scraped. For identification or aesthetic purposes, some materials can be beforehand dyed to avoid two coloring processing for free and expensive. Detailed overview
The second chapter of polyamide (PA66)
4. excellent electrical insulation performance. Nylon has a high volume resistance and high breakdown voltage. It is an excellent insulating material for electrical and electrical appliances.
5. good climate resistance.
6. water absorbency. The water absorbability of nylon is large, and the saturated water can reach more than 3%. To a certain extent, it affects the dimensional stability of the parts
Two application
With the development of petroleum chemical industry and other industries, it provides rich and inexpensive raw materials and broad market for the development of nylon engineering plastics.
Nylon is mainly used in automobile industry, electrical and electronic industry, transportation, machinery manufacturing industry, wire and cable communication industry, film and daily necessities.
The nylon used in the automobile industry is about 1/3 of the total nylon consumption. It is mainly to use the nylon tree with small density and excellent comprehensive properties to adapt to the steam.
The demand of light weight and energy saving is required. Especially with the advantages of good mechanical strength, wear resistance, oil resistance and self lubrication, all kinds of bearings, gears, and gears are made.

Water chamber, brake pipe, engine hood, door handle and so on.
PA612 Besides the general PA characteristics, PA612 has the advantages of relatively small relative width, lower water absorption and density, good dimensional stability, high tensile strength and impact strength, and transparency.
