- Q:What is plastic material E-PET?
- With the prevalence of the hardware industry, more industry technology is dazzling, and the technology that we know may not be even longer, so here we are talking about what is the real PET plastic.Polybutylene terephthalate mainly consists of polyethylene terephthalate two (PET) and polybutylene terephthalate (two) (PBT).PET is highly symmetrical and has certain crystalline orientation ability, so it has high film forming ability and plasticity. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance, friction and dimensional stability, and electrical insulation. PET bottles are widely used because of their high strength, good transparency, non-toxic, impermeable, light quality and high production efficiency. PBT and PET molecular chain structure similar, most of the same nature, but the main chain from two methylene into four, so the molecules are more supple, processing performance is better.
- Q:How do plastic raw materials trade? How big is the market?
- At home, the whole plasticizing industry chain is almost 3 trillion of the big market, and the annual growth rate of 20%.
- Q:What material do you need for plastic film? Do you use this material?
- In addition, the bag color and performance requirements are not high, you can choose recycled polyethylene. Plastic can be recycled, because of the repeated use of processing, non-toxic, tasteless new plastic become cloudy, less than the original hygiene and color requirements. But this plastic bag is made from recycled material, which is environmentally friendly, and the price is 10% to 50% lower than that of the new material bag
- Q:I made of plastic raw materials accessories containing benzene, how to remove the teacher, please enlighten!
- Plastic generally does not contain benzene, ah, only polystyrene, ABS and other plastic molecular structure containing benzene ring, is a high polymer. Benzene is an organic solvent, low molecular substances, boiling point is low, very volatile.
- Q:What is Ms plastic material?
- Copolymerization of styrene and methyl methacrylateMS resin is commonly used transparent plastic raw materials, general injection molding and extrusion molding, transparency of nearly PMMA, for optical components / toys / lampshades, lighting, /OA accessories / food containers / household appliances / building materials, etc.
- Q:What is the essential difference between plastic raw materials and engineering plastics?
- Plastics can be divided into two major categories: General Plastics and engineering plastics. They are usually granular or powder in order to be easy to process before they are madeGeneral plastics refer to common plastics with large output, wide use, good formability and low price. Such as PVC, polyethylene, polypropylene, polystyrene and so on. Products made of plastic film, pipe, woven bags and plastic daily necessities. The yield and consumption of general-purpose plastics account for more than 80% of all plastics.Engineering plastics refer to plastics that meet the needs of industrial parts. Relatively speaking, they yield large, wide range of applications. Mainly ABS, polycarbonate, nylon, POM, modified polyphenylene ether, thermoplastic polyester and so on. Products have TV casing, plastic gears, optical materials, gaskets and so on.There is also a special engineering plastics, in addition to its characteristics of engineering plastics, its comprehensive performance is higher, long-term use temperature above 150 degrees celsius. It also has special functions and special uses. Mainly used in high-tech industries, such as atomic energy, rockets, satellites, aerospace, automotive, electronic and sports equipment, and other structural materials. Commonly used special engineering plastics are fluorine plastic, silicon resin, polyimide, peek, liquid crystal polymer and so on.
- 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 concepts, classifications and distinctions of modified plastics and plastic materials?
- Concept: modified plastics, refers to the base of the general plastics and engineering plastics, after filling, blending and enhancement processing method of modification, improve the performance of flame retardant plastic products, strength, impact resistance, toughness.Classification: modified plastic products are mainly a variety of flame retardant resins, toughening resin, plastic alloy, functional masterbatch etc..
- Q:How do you increase the transparency and hardness of PP plastic suction pipes? What raw materials do you need to add?
- Add transparent nucleating agents to improve transparency, such as milk tea cups
- Q:What are the bulk density, size and moisture content of the general plastic material?
- Among them, the mass of the material has nothing to do with the particle size, but the larger particles have larger volume due to the presence of more voids between the particles. Small particles (powder) to the general packing is very tight, so the smaller bulk density.
