Q:What two ingredients fit together to solidify like plastic?

What is the material of plastics? This is important because even the adhesive with high bond strength can not be well adhered to on some surfaces, such as PTFE.

Q:How do plastic raw materials trade? How big is the market?

Plastic raw material industry chain is divided into upstream petrochemical enterprises, midstream large agents, distributors at all levels, and downstream terminal manufacturers.

Q:What are the common raw materials used in plastic bottles? What are the main features?

PP bottles are non-toxic, transparent, and have certain heat resistance and impact resistance. They are generally loaded with fruit juice and shampoo. They can be hot filled (very important for fruit juice drinks). They can not be sterilized by pressure cookers, and their transparency is poor.

Q:What are the raw materials of plastics made of?

Synthetic resin refers to coal, petroleum, natural gas, calcium carbide and some agricultural products as the main raw material, the low molecular weight compounds prepared firstly has certain synthetic conditions (monomer), and then through chemical and physical methods for the synthesis of high molecular compound. The characteristics of this kind of compounds similar to natural resin (such as rosin, shellac, amber, etc.), but the performance and more superior than the natural resin.

Q:What is plastic film material?

You should first say what type of plastic film you are going to make. You should make a bag or make a plastic wrap. The type is different. You should see what determines what material to use, and the plastic film is also divided into many kinds

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:Plastic raw materials packaging is generally divided into several categories?

A variety of kraft paper, polyethylene thick film, fiber bags, aluminum foil bags

Q:What are the POE plastic raw materials?

Poe plastic raw material comes from petroleum or natural gas as the raw material of petroleum chemicals. It is a kind of macromolecule resin obtained by polymerization.

Q:What material is best for plastic gears?

At present, the demand for plastic gear with high wear resistance and noiseless gear is very strong. POLYMSJ noiseless nylon composite occupies a leading position in this field. If it doesn't solve the problem, you can try it out.

Q:What is the difference between PP raw material and modified PP?

Sort:(1) according to the characteristics of resin when heating and cooling, classification: 1. Thermosetting plastics, two, thermoplastics(2) according to the use of plastics classification: general plastic, engineering plastics, special plastic raw materialsModified PPThe concept of modified plastic PP, 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: PP modified plastic products are mainly a variety of flame retardant resins, toughening resin, plastic alloy, functional masterbatch etc..
