Q:Is plastic raw material rubber?
Raw materials are polymers of polymers such as polypropylene. Is generally from the fossil raw materials inside the extraction after polymerization together. A series of plastic refers to the resin as the main component, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials. To put it simply, the oil was extracted and finally made into plastic, rubber and plastic
Q:What is the difference between EPS plastic particles and PS? What materials are represented?
EPS is a foaming agent that is used to make foam, which is the white foam that is packed in the TV and refrigerator.
Q:What can be added to the PP plastic material to prevent light transmission?
PP material suppliers to remind you, PP plastic raw materials to add sunscreen, adding black masterbatch or impact PP raw materials on the line
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:Is the plastic with high melting index good?
Its test method is: first let the plastic particles in a certain time (10 minutes), under certain temperature and pressure, melt into plastic fluid, and then through a diameter of 2.1mm tube g (grams) outflow. The greater the value, the better the processability of the plastic material, the worse the contrast.
Q:What are the materials for making plastic basins? Are they raw materials?
The plastic washbasin is made of PP plastic(polypropylene is a thermoplastic resin made by the polymerization of propylene.)Is a relatively traditional washbasin, anti wrestling performance is very strong.Although the modern bathroom, a variety of shapes, materials, fashion basin are,But still can not do without this traditional plastic basin.
Q:What plastic material has great impact resistance?
The ability of metal materials, machinery parts and components to resist impact damage is called impact strength.
Q:Characteristics and uses of CA plastics
Commercially available products can be divided into general cellulose acetate (acetyl - 37% - 40%). Plasticizers are often added as injection molded parts, such as toothbrushes, brushes, etc.. Cellulose acetate with a high acetyl content (40% to 42% acetyl), white, granular, powdery or cotton solid. The light stability, not easy to burn, in dilute acid, gasoline, mineral oil and vegetable oil in stability, swelling in chloroform, insoluble in acetone, methyl acetate, can dilute alkali erosion, has advantages of toughness, transparency, good gloss, good melt fluidity, easy molding. Dichloromethane homogeneous method using refined cotton linter and acetic acid with acetyl sulfate as catalyst, esterification, hydrolysis in the presence of dichloromethane solvent, can be combined with cellulose acetate acetic acid content in 60% + 0.5% range. The traditional method is to use dry cotton, acetic acid in the presence of catalyst activation, sulfuric acid, acetic acid and acetic anhydride with mixture of acetylation, then adding dilute acetic acid hydrolysis to belong to the degree of substitution, and catalyst, precipitation, acid washing, rice drying. After partial hydrolysis, cellulose acetate is called two, and the degree of esterification is 220~270. Without hydrolysis, that is, the degree of esterification, the gamma value of 300, said three cellulose acetate. Two cellulose acetate plastic handle, can do all kinds of tools of computer and typewriter alphanumeric keys, phone chassis, car steering wheel, textile equipment parts, radio switch and insulation, pen, spectacle frame and lens, toys, daily necessities, but also do desalination membranes. Three cellulose acetate, high melting point, can only match into solution processing, used as a movie film, X film, light film, electromagnetic diaphragm insulating tape, transparent container, the silver zinc battery.
Q:Application of CPE in plastics industry
Chlorinated polyethylene (CPE) for saturated polymer materials, the appearance of white powder, non-toxic and tasteless, has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, good oil resistance, flame retardancy and coloring properties.
Q:What kind of plastic material is used for medical instruments?
Plastic) inevitable in the process of polymerization reactor, to come into contact with the metal catalyst. Often contain trace metal ions, according to the national standard of medical plastic, residues are clearly defined for zinc, lead, cadmium, copper, barium, tin and other metal ions;
