- Q:What is the hardness of PAEK+30%GF plastic material?
- Mohs hardness is mainly used in mineral classification. The Mohs scale from I to 10. the scratch resistance increasing (such as talc Mohs hardness is I, the diamond is 10), namely each scale corresponding to the Mohs material can be scraped traces in the previous stage of material. According to the Mohs hardness can determine the scratch resistance between contact with objects in the use of Engineering plastics.Engineering plastics Mohs hardness is between 2 and 3.
- Q:How many kinds of plastic do you have?
- Engineering plasticsGeneral engineering plastics include: polyamide, POM, polycarbonate, modified polyphenylene oxide, thermoplastic polyester, ultra high molecular weight polyethylene, methyl amyl polymer, vinyl alcohol copolymer, etc..Special engineering plastics are crosslinked and non crosslinked. The crosslinked types are poly amino bis maleic amide, poly three triazine, crosslinked polyimide, heat-resistant epoxy tree fingers and so on. Non crosslinked types are polysulfone, polyethersulfone, polyphenylene sulfide, polyimide and PEEK.
- Q:Plastic raw materials, why LDPE and LLDPE?
- LDPE is a low density polyethylene with a large number of branched structures. The molecular structure is lack of regularity, so the crystallinity of LDPE is small, 65%~75%, and the density is low, 0.91~0.93 grams / cubic centimeter. LLDPE is a linear low density polyethylene. Its molecular structure is linear, branched less, branched short, and its density is similar to that of LDPE. Its physical and mechanical properties are better than those of LDPE.
- Q:What can recycled plastics do?
- Plastic has good processability, easy to shape, such as: blow, extrusion, pressure, easy cutting, easy welding. In daily life there are many plastics can granulation, such as waste food bags, sandals, wire, plate, agricultural film, pipe, barrels, pots, and packaged with all kinds of waste plastic products can be repeatedly processing, production of plastic raw materials, through special process and formula for making machine parts and components; the system can be used for water, farm machinery, packing bag, cement bag;
- Q:What are the plastic raw materials for this purpose?
- From the bathroom supplies we use when we wake up, the tableware we use for breakfast, the stationery we use for work and study, the seat cushion for sleeping, the mattress, and the shell of TV set, washing machine and computer
- Q:What are the materials for making plastic basins? Are they raw materials?
- PP material ah! Usually with raw materials, slightly more mouth material!
- Q:What is the difference between PA66 and PA6 plastic raw materials? Differences in price, color, performance, etc
- PA66 (polyamide 66 or nylon 66) is more widely used in the automotive industry, instrument shells, and other products that require impact resistance and high strength than PA6, PA66.
- Q:How many kinds of raw materials are there for blowing plastic bottles?
- Plastic bottles are made of polyethylene or polypropylene and added a variety of organic solvents. Plastic bottles are widely used in polyester (PET), polyethylene (PE), polypropylene (PP) as raw material, add the corresponding organic solvent after high-temperature heating, the plastic mold by blow molding, extrusion blow or injection molding of plastic containers.
- Q:What material is good for plastic bellows?
- In the cases to recommend the use of PE (polyethylene) bellowsNo oxidizing acids, no environmental oils, vegetable oils, mineral oils, no organic solvents such as aliphatic hydrocarbons, aromatic hydrocarbons, ketones, esters, etc..Mainly used in the temperature range of -40 to 80 degrees Celsius environment; used in automobiles, motorcycles and other motor vehicle wire harness sheath; also used for household appliances, precision machine tools and other equipment wiring wire sheath.
- Q:That kind of plastic bottle blows well
- PETA hard, tough, high strength, bright surface with transparent and multi colored sheets. The disadvantage is PET high frequency synthesis is difficult, the price is a bit more expensive than PVC, this material is often high-grade products and environmental requirements of the user to replace the PVC PET material generally used to make packaging for food, beverage, pharmaceutical plastic bottles.
