II.                ProductDescription

Theseproducts used PVC resin as base materials, and added nanometer conductivecarbon black as filling, by mixing, plasticizing, pelleting, and finished aspellets. These products have very good conductive and processingcharacteristics. And it mainly substituted the graphite coat structure.

In theformula, it decreased the affect of plasticizer to conductive carbon black bythe technology of toughness reinforcing. At the same time, reduced the affectof materials low temperature and processing properties, because adding masscarbon black in the products. And we selected suitable low temperatureadditiver and rheological agent to improve the PVC materials, and made it hasgood integrated properties.  

III.              Processing

Use singlescrew extruder to process, suggest to put one layer 60/80 strainer.

Thefollowing temperature(℃) profile of extruder is recommended:

Q:What are the requirements of laser marking for plastic products?
Compared with other materials, plastics have the following characteristics: light weight, excellent chemical stability, excellent electrical insulation performance, wide mechanical strength distribution and higher specific strength. Based on the above characteristics, become the most commonly used plastic packaging materials, plastic products trademark, barcode and number for identification mark printing, usually by labeling, packaging and other processing methods of hot stamping contraction, or directly at the surface of the plastic mechanical processing, such as printing, engraving, punching and pressing
Q:Is chlorine dioxide corrosive to plastic products?
As long as there is no water or steam, it does not react.
Q:Is PC the same as plastic?
The general use of PC material equipment high temperature resistant, durable, anti bacteria is very good
Q:What are the parts of plastics and what are their characteristics?
The so-called plastic, in fact, it is a kind of synthetic resin, the shape of the natural resin with pine resin similar to, through chemical means of artificial synthesis, and is called plastic.
Q:What are the main features of plastics?
Some plastic as hard as stone, steel, such as paper, some soft leather; from the plastic hardness, tensile strength, elongation and impact strength and other mechanical properties, wide distribution, great use of choice. Because of the small proportion and high strength of plastics, they have higher specific strength. Compared with other materials, plastics also have obvious disadvantages, such as easy combustion, poor stiffness, high metal resistance, poor aging resistance, and non thermal resistance.
Q:How do I see if the plastic cup is qualified?
They attach triangular recovery marks to plastic products and use figures 1 to 7 and English abbreviations to refer to the type of resin used in plastics.
Q:White plastic products used for a long time will be yellow, how to do?
There is a white board cleanser on the market, and it works well. For example, when the computer has turned yellow, it will be good to wipe with this.
Q:What products are plastic extrusion?
In addition to granulation, are hollow plastic products are extrusion molding
Q:What kind of plastic can touch food?
It is better to wear plastic without color. The color is usually processed and not clean!
Q:Is ABS plastic poisonous?
Of course, due to the application of different plastics will add different additives, but the difference is very big. Different plastic plastic additives are generally inorganic filler, glass fiber, pigment, antioxidant, anti UV agent, plasticizer and inorganic filler and glass fiber. The body is stable and has no toxicity to the mineral glass. The human body. The antioxidant and anti UV agent general dosage is small, but 1-2% of the components, of course the nature itself is non-toxic or low toxic to the human body. The most likely risk of plastic is PVC, the plastic additive content could even reach 60-70%, it is difficult to ensure there is no harm to human body.
