FAQ

I made of plastic raw materials accessories containing benzene, how to remove the teacher, please enlighten!
The use of benzene: fats, resins and iodine and other solvents. Determination of mineral refractive index. Organic synthesis. Optically pure solvent. High pressure liquid chromatography is used as solvent, synthetic dyes, pharmaceuticals, pesticides, petroleum and chemical products, photographic materials, varnishes, nitrocellulose lacquer thinners, paint remover, lubricating oil, grease, wax, Sai Luluo, resin, artificial leather and other solvents. It must be the raw material you bought that contains some other additives. Benzene is not removed
What are the raw materials for producing plastic bowls and cups?
Now the plastic bowl is basically made of PP, the quality is better. What's more, the PP bowl can be baked in a microwave oven, and other plastics will not.
What are the properties of plastic material PS? What are the advantages and disadvantages?
High temperature, high mold temperature and low injection pressure should be adopted to prolong the injection time. It is beneficial to reduce internal stress and prevent shrinkage and deformation
Raw materials for making plastic bags
The common food plastic bags are made of polythene film. The film is non-toxic and can be used to hold food. There is also a film made of PVC, PVC itself is non-toxic, but according to the use of film additives are often harmful to human substances, has a certain toxicity. Therefore, this kind of film and plastic bag made of this film should not be used for containing food.
What are the raw materials for making plastics?
Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, noise elimination, and excellent performance
What type of raw material is used in plastic bags? The brightness is good. It blows out as bright as a mirror! That kind of transparency!
High density polyethylene (LDPE) transparency, the equivalent number can reach about 90%, but the temperature should be controlled well, there is no general problem, that is, the cost is higher than other products
What is the ash content of PP plastic raw materials?
PP if a few raw materials mixed with ash, and the color of raw material and color, it is PP powder, the water can not be dissolved. Try, if it is more, and the color is white, it is talcum powder or toner, water or dissolved or muddy water
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.
