Q:PP plastic stool surface with those raw materials, what is the ratio?

PP has good stress cracking resistance and has a high bending fatigue life, commonly known as "fold gum"".The comprehensive performance of PP is better than that of PE.

Q:How to use all kinds of plastic materials?

AS (SAN) acrylic styrene transparent adhesiveAS is acrylonitrile (A), styrene (S) copolymer, weather resistant medium, not by the high humidity environment, ability, general oil, detergent and mild alcohol, poor fatigue resistance, not easy to crack due to stress, material quality high transparency, good liquidity in ABS.Suitable plastic products: tray, cups, cutlery, toothbrush, refrigerator cabinet, knob, lighting accessories, accessories, instrument mirror, packing box, stationery

Q:What kind of material is the plastic bag commonly used in supermarkets now?

Another is PP or OPP, which contains bread and crackers. The material is smooth and very transparent, but the tightness is not very good and there is no tension.

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:Can PE material be used as food grade plastic?

Yes, of course, but the raw material suppliers have already divided the ingredients into food grade, and they will be used in non food occasions to contain substances harmful to the bodyFor human health, please choose food grade PE materials, and note that the highest temperature can not exceed the manufacturer's maximum limit, otherwise the material will appear unstable, resulting in harmful substances

Q:Pollution in the production of plastic raw materials from petroleum production

Oil separates compounds of different components by distillation. Through this process, liquefied gases (alkanes, olefins, etc.), diesel, gasoline, bitumen, etc. (from gas to solids) can be separated. In addition, plastic monomers can be prepared from naphtha or natural gas in synthetic plastics

Q:What material is best for plastic gears?

Gears can be made of PA, POM, etc., but PA and POM will have noise at high speeds.

Q:What are the concepts, classifications and distinctions of modified plastics and plastic materials?

Modified plastics should, in principle, be made from the plastic raw materials produced by petrochemical plants. By adding plastic additives, they can enhance their hardness, fire resistance, high temperature or low temperature, weather resistance and ultraviolet resistance. Therefore, modified plastics are processed from plastic raw materials, which is the relationship between source and flow.

Q:Chemical, plastic raw materials, plastic raw materials how sub grade?

Plastic bucket is usually added to the resin, in the production of lubricants, plasticizers, dispersant, pigment, polyethylene wax, and these materials good variety, price range, and some high melting point, good whiteness, production out of the finished product is good texture, high brightness, good conscience manufacturers add some heat thermoplastic elastomer, feel very well; and a point of the raw materials, the relative performance is low, the production of plastic barrels must be of poor quality.

Q:What are the main raw materials of plastic products?

PS plastic (polystyrene) English Name: PolystyreneSpecific gravity: 1.05 g / cubic centimeter molding shrinkage: 0.6-0.8% molding temperature: 170-250 DEG C drying conditions: ---The material properties of electrical insulation (especially high-frequency insulation) excellent, colorless and transparent, light transmittance after organic glass, color of water resistance, good chemical stability and strength. In general, but the crisp, easy to produce stress cracking, no resistance to benzene. Gasoline and other organic solvents. Suitable for making insulating transparent ornament and. Chemical equipment. Optical instruments and other parts.Molding performance 1. amorphous material, moisture absorption is small, not to be fully dry, not easy to break down, but the coefficient of thermal expansion is large, easy to produce internal stress. Better liquidity, can be used screw or plunger injection molding machine
