- Q:What are the raw materials of foam plastics and how do they come out?
- The foaming agents for epoxy resins are two types: physical foaming agents and chemical foaming agents. Physical foaming agents are mainly low boiling liquid, such as three chloro methane (F11), three chlorine, three fluorine ethane (F112), two chlorine, two fluorine methane (F12) and so on. By using the curing heat of the epoxy resin, the liquid with low boiling point is evaporated, and the gas is released, and the products are small in density and low in thermal conductivity. But fluorine hydrocarbons have a damaging effect on the atmosphere and are often used to spray foaming processes. According to the experts of China epoxy resin industry association, toluene and so on can be used as auxiliary foaming agent. In addition to foaming, it also acts as a curing reaction, a heat absorber and a diluent.
- Q:Dissolve in 0.3 of the LDPE plastic raw materials what?
- The molecular structure of the conventional LLDPE is characterized by its linear backbone, with only a few or no long branched chains, but contains some short branched chains. Without long branched chains, the crystallinity of polymers is higher.In general, LLDPE resins are characterized by density and melt index. The density is determined by the concentration of comonomer in the polymer chain. The comonomer concentration determines the short branch chain in the polymer. The length of the short branched chain depends on the type of comonomer. The higher the concentration of comonomer, the lower the density of the resin. In addition, the melt index is a reflection of the average molecular weight of the resin, mainly determined by the reaction temperature (solution method) and the addition of chain transfer agents (gas phase method). The average molecular weight is independent of the molecular weight distribution, and the latter is mainly influenced by the type of catalyst.
- Q:What kind of plastic material is used for medical instruments?
- You need to add various additives in plastics processing or modification process, such as in the PVC medical products in the amount of the plasticizer is as high as 30 - 60%, so as far as possible the use of non-toxic additives, long-term use to prevent or reduce the additive precipitation, so as not to affect the product performance and the therapeutic effect;
- Q:What is the difference between PA66 and PA6 plastic raw materials? Differences in price, color, performance, etc
- PA6 also known as nylon 6 is translucent or opaque white particles, thermoplastic, light weight, good toughness, chemical resistance and good durability and other characteristics, generally used for auto parts, machinery parts, electronic products, engineering accessories and other products.
- Q:What is the raw material used in the production of plastic products?
- Cling film, plastic film are such materials, heat resistance is not strong. Usually qualified PE cling film will appear hot when the temperature exceeds 110 degrees, and will leave some plastic preparations which can not be decomposed by human body. And wrapped with plastic wrap food heating, food grease is easy to preserve the harmful substances dissolved in the film. Therefore, the food into the microwave oven before, to remove the cling film wrapped.
- Q:ABS plastic storage conditions
- If it is ABS raw materials, storage: rainproof, moisture-proof, anti lightPacking is best provided with a PE inner bag for moisture proofThere is no place to pay more attention.
- Q:How do you increase the transparency and hardness of PP plastic suction pipes? What raw materials do you need to add?
- Choose the right material. If you don't think the transparency is enough, you can add a nucleating agent to modify it. PP's common transparent nucleating agent has the ability to increase transparency and improve the surface hardness of the product. Yuyao Zhenyi plastic
- 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:What is the material of plastic flat screen?
- Widely used in aquaculture, poultry farming, sericulture, civil construction, aquaculture, garden care, keep the field of railway and highway subgrade reinforcement, etc., can also be used for mattress, sofa cushion, car cushion, which is characterized by low cost, long service life.Material: high density low pressure polyethylene (PE), polypropylene (PP), ABS plastic particles.Colors: black, white, orchid, green, yellow, red and so on.
- Q:What are the raw materials for vest plastic bags?
- Polyethylene (Polyethylene, PE), referred to as PE. It is a high molecular organic compound which is made up of ethylene. Polyethylene is recognized as the best food for contact with food in the world. Non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, anti - oxygen, acid, alkali, air tightness, heat sealing and other outstanding performance. Known as "plastic flowers" laudatory title. It is the most important and most important material in plastic packaging and printing.
