- Q:What is the difference between PPA plastic raw material and PP?
- Two kinds of materials are two grades, figuratively speaking, PPA is Benz, PP is alto.
- Q:What is the specific material for plastic pallets?
- Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.
- Q:Is the plastic with high melting index good?
- It was established by the American Society for measurement standards (ASTM), a method used to identify plastic properties, according to the DuPont Co (DuPont).
- 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 material is good for plastic bellows?
- In the next case, it is recommended to use PA6 (nylon 6) bellowsNo sulfuric acid, formic acid, acetic acid, nitric acid, hydrochloric acid, calcium chloride, methanol and strong oxidant in the environment; in the heat dissolved in ethylene glycol, acetic acid, ethanol, propylene glycol, 1 chlorine, 5 diol, trichloroethylene, zinc chloride, methanol, phenol, cresol solvent etc..Mainly used in the temperature range of -34 to 150 DEG C in the environment; for automobiles, motorcycles and other motor vehicle sheath wire harness sheath; can also be used for household appliances, precision machine tools and other equipment for electric wire harness; have good stability of various oils of animal and plant oil and mineral; resistant to various concentrations of alkali.
- Q:PVC what chemicals do you need for plastic surface treatment?
- The choice of surface treatment methods, because most of the plastic surface can be low, many processing methods, such as decoration, printing, spraying and so on, can not be directly applied, and the need for surface treatment first
- Q:What do you mean by grade 1, class two or class three in plastic?
- Three grade material refers to the raw material has been used two times or more times, the processing of particles, and its elasticity, toughness and other aspects are not very good.
- Q:How are plastic products made? What is the raw material of plastics?
- 1, simply say, use an injection molding machine to melt the material at high temperatures and then inject the mold into the mold at high pressure.2, raw materials are materials that have not been processed. Plastic raw material is standing (smaller than soybean).Generally ABS, PS, PP, and so on, these materials are not the same.3, melting at high temperatures, and stamping (I haven't seen)4, iron or steel mold, to see what your home appliance plastic parts, what kind of mold is it!
- Q:Plastic PPT30S add what material will increase hardness?
- Technical parameters of Qilu Petrochemical PP (T30S)Project quality index test method of isotactic index% greater than 95 GB/T 2412 powder ash%, less than 0.03 GB/T 9345 tensile yield strength greater than 28 GB/T, MPa 1040 kg/m3 0.9~0.91 density, cleanness, color particle, /kg melt flow rate of 11~20, g/10min 2~4 GB/T 3682 brand name: Qilu
- Q:Plastic raw materials packaging is generally divided into several categories?
- 1, cattle cardboard fiber bag; "such as: GPPS, HIPS CMO ABS, are using this package, he is in some plastic packaging,2, fiber bags, plastic bags, such as PP or PVC, PE and so on3, plastic bags, Exxon, Teijin etc.4, plastic bags contain tin and platinum paper, for sealing requirements or moisture absorption of the material packaging5, kraft paper bags, PBT, PET, PPS, PA and so on
