Q:What is the concept of plastic raw materials for turnover containers?

Plastic turnover box, other features: 1) plastic turnover box outer dimension refers to the maximum size of the logistics box cover. 2) the plastic turnover box has no standard inner concave, and the case size is 18mm. 3) the carrying capacity of a plastic turnover box means that the load is uniformly placed within the range of the environmental temperature. 4) the effective working temperature of the plastic turnover box is -25 DEG C - 40 DEG C. 5) plastic turnover boxes can be stacked for storage, saving space.

Q:How many kinds of plastic do you have?

General plasticsThere are five kinds of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile butadiene styrene copolymer (ABS)

Q:Is plastic raw material rubber?

The difference between the plastic and the rubber is plastic or not, but because of thermosetting plastics, this definition is not comprehensive. Another difference is whether the elastic body, but because of the appearance of thermoplastic elastomer, this definition is not comprehensive. In general, rigid high molecular material thermoplastic processing, sure is a plastic elastomer; and thermosetting rubber must be classified. The more ambiguous reference history. Silicone rubber and polyurethane is thermosetting elastomer rubber, is, but completely different from natural rubber. There is a part of polyurethane is thermosetting plastics, even thermoplastics, composition, structure and it depends on the characters.

Q:What does MFI mean in PC material?

The measurement of MI is usually based on the standard method of ASTM D1238. It is the principle of the plastic or resin into the metal sleeve of a fixed inner diameter, and heating the plastic or resin after melting, and then give some load on the piston, the piston on the weight of the molten plastic has been squeezed out from a small hole in the charge, and calculate the weight and squeezed out of plastic. This measuring method, because of the same material, the sleeve barrel inner diameter, load, and temperature are fixed, so in addition to test MI, can also be used for the determination of density, viscosity, and melt shear rate, shear stress... etc.

Q:What does plastic material include?

The main raw material of plastics is oil and natural gas, that is, carbon hydrogen compounds. First, the appropriate large molecules in petroleum and natural gas are extracted, first split into monomers, and then polymerized into polymers to become plastic.

Q:What is the difference between plastic particles and raw materials?

Special plastics: thermosetting plastics, functional polymers, plastics, such as artificial kidney. Heart. Blood vessel。 Aerospace industry, etc.

Q:What kind of plastic material is used for medical instruments?

The resin used for medical plastic requires higher purity and narrower molecular weight distribution;

Q:What plastic material is resistant to high temperature?

PPS is a kind of special engineering plastics with excellent comprehensive performance. Dimensional stability of PPS has excellent temperature resistance, corrosion resistance, radiation resistance, flame retardant, balanced and excellent physical and mechanical properties and excellent electrical properties and other characteristics, are widely used as structural polymer materials, by filling after modification, widely used in special engineering plastics. At the same time, it can be made into various functional films, coatings and composite materials. It has been successfully applied in the fields of electronics, electrical appliances, aeronautics and Astronautics, automobile transportation and so on. Domestic enterprises have actively developed and formed a certain production capacity, which changed the situation of relying solely on imports in the past. However, there are still some problems in China's PPS technology, such as low variety of products, high functional products, and urgent expansion of production capacity, which will be the focus of the next development of PPS.

Q:What raw materials do plastic color printing plants use?

PEBOPPOPS film, aluminum film and so on, the ink is usually water-based ink, polypropylene ink, etc., different films with different ink.

Q:How to test plastic raw materials?

Contrast the appearance quality of raw materials, separately open 1~2 bags, take out a little plastic particles, contrast the size and color of the plastic particles in each bag. And compare the same batch of plastic particles with the previous batch. There were no obvious differences in the color and graininess of the raw material particles in different packaging bags and batches
