FAQ

What is the hardness of PAEK+30%GF plastic material?

Polypropylene plastic (PP) hardness is Rockwell hardness 48. General plastics Rockwell hardness, Brinell hardness and Rockwell hardness measurement, not with Mohs hardness measurement. The hardness of nails is not measured, so it is difficult to compare with the data, I think the hardness should be quite.

Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?

Plastic pipe is usually plastic resin as raw material, adding stabilizers, lubricants, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading tubes, and so on.

What is the difference between plastic particles and raw materials?

PP recycled plastics profile: polypropylene (PP) - coloring not translucent, waxy, lighter than polyethylene, transparency is better than polyethylene, polyethylene than rigid. Mainly used for pots, barrels, furniture, thin film, woven bag, packing tape, bottle cap, car bumper.PE recycled plastics: Polyethylene (PE) - no coloring milky white translucent, waxy; touch smooth feeling, soft and tough, slightly elongated, generally low density polyethylene is relatively soft, good transparency, high density polyethylene hard. Mainly used for plastic film, bag, water, oilPS is polystyrene plastic. It is easy to dye and transparent. It is used to make lampshade, toothbrush handle, toy and electrical appliance parts. It is resistant to acid and alkali corrosion, but easily soluble in chloroform, two vinyl chloride, banana water and other organic solvents.

How to identify the proportion of nozzle material in plastic?

Generally within 15% is allowed; if the nozzle is too much will cause the following phenomenon: product strength decreased, brittle, easy to crack; cause accelerated aging

Can PE material be used as food grade plastic?

Yes, but the raw material suppliers have already divided the ingredients into food grade, and they will be used in non food occasions to contain substances harmful to the body

What raw material produces the plastic to the human body not to harm, to the environment does not have the pollution?

Starch plastics containing starch in more than 90%, add other components also can be completely degraded, there are Japan Sumitomo Business Corporation, American Wamer-Lamber company, Italy Ferrizz company claims of success starchier in 90% to 100% of full starch plastics, in (January ~ 1) completely biodegradable without leaving any trace, no pollution, can be used in the manufacture of various containers, bottles, films and garbage bags etc. all starch plastics production principle is that the starch molecular allostent anddisorderly change formed with thermoplastic starch resin, also known as the thermoplastic starch plastics. The molding process can be used in traditional plastic processing equipment. With starch as the potential advantages of development of bio degradable plastics raw materials: starch has biodegradability completely in various environments; plastic in the degradation of starch molecules or after ashing, the formation of two oxygen Carbon gas, without soil or air poison; take appropriate technology to make starch thermoplastic after mechanical properties can reach for manufacturing plastic material; starch is a renewable resource, inexhaustible, pioneering starch utilization is conducive to rural economic development. That is, starch plastics production in China of vast the majority of starch filled plastics, is added in a certain proportion of polymer materials in non biodegradable starch, resulting in the collapse of material physical property through biodegradation of starch, prompted a large number of end groups that exposed to oxidative degradation, but the rest of the "collapse" after the PE, PVC and so on are not always possible degradation the residue in soil, of course, days and months multiplying will cause pollution, so the foreign ownership for such products will be eliminated.

ABS plastic storage conditions

Plastic materials generally react with light and oxygen for a long time to become yellow and brittle

Chemical, plastic raw materials, plastic raw materials how sub grade?

Plastic bucket is usually added to the resin, in the production of lubricants, plasticizers, dispersant, pigment, polyethylene wax, and these materials good variety, price range, and some high melting point, good whiteness, production out of the finished product is good texture, high brightness, good conscience manufacturers add some heat thermoplastic elastomer, feel very well; and a point of the raw materials, the relative performance is low, the production of plastic barrels must be of poor quality.
