The biggest advantages of PC are good strength, toughness, good looks, and certain flame retardancy. There is nothing to say about the strength of engineering plastics, and because of poor crystallinity, the transparency of PC is very high, about 89-90%, and the PMMA with the best transmittance can be referred to is 92-93% (of course, these two or three percentages determine many industries), and because PMMA is not scratch-resistant, many fields with optical and strength requirements need PC. The coloring performance of PC plastic is also very good, and the color paste is not easy to migrate during masterbatch processing, so the color of colored PC is saturated and uniform, and the surface is smooth, so when it is also colored plastic, PC looks much better than HDPE and PVC.
Poor flame retardant performance is a large application of plastics, PC is okay in this regard, and it is extinguished when it is out of fire. The disadvantage is that the processing temperature is too high and the energy consumption is high; Hydrolysis resistance is poor. The main advantages of PP are inert, oil and water resistance, and corrosion resistance, which also makes PP have obvious application advantages in the food industry; But in addition, PP basically has no strong points, such as transparency, even if the improved transparent PP is pediatric in front of PC.
AS can be regarded as a synthesis of polyacrylonitrile and polystyrene, most of the materials containing acrylonitrile have good solvent resistance, the same is true of AS, and the strength of AS is also very high, but compared with ABS plastics, due to the lack of butadiene, the toughness of AS is insufficient, and like all styrene-containing plastics, the yellowing resistance is not high, and it is not as common as the previous two in the food industry, and it is mostly daily necessities.

Not all PP materials are food-grade, and PP materials related to the orange food industry are food-grade.
Food-grade PP material will not dissolve harmful substances under normal conditions and high temperatures, but if it is an industrial-grade PP material, harmful substances will be dissolved at room temperature or high temperature, which will cause harm to human health. Therefore, when it comes to the use of PP materials, food must be used food grade, if the use of industrial grade will cause great harm to the human body.
At present, PP material is a plastic that can be heated in a microwave oven, and has high strength and folding resistance, and will not be damaged if it falls from a height of 50,000 times to 20 times. Food-grade PP sheet is commonly used with quick-frozen dumplings and microwave heating food packaging.
PP material introduction:
PP material is polypropylene, polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer, is currently one of the lightest varieties of all plastics. It is particularly stable to water, with a water absorption rate of only about 80,000 to 150,000 molecular weights. The formability is good, but due to the large shrinkage rate (1% to.
Thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy, and the surface gloss of the products is good.
PP polyester is an amorphous material, its melting point should be above 220, and its heat deformation temperature should be about 121 degrees, but because it is a macromolecular polymerization after all, the higher the temperature, the greater the possibility of precipitating small analytical oligomers, and most of these substances are not conducive to human health, and according to the customer's use, the general boiling water is 100 degrees, so the general plastic cup will not be marked more than 100 degrees.

Pro-[warm] PP material (polypropylene) is generally considered to be a food-grade material. Polypropylene is a plastic material with good chemical stability and high temperature resistance, and is commonly used in the manufacture of food packaging, food containers and food contact utensils. Food-grade materials are materials that meet food safety standards, can come into direct contact with food, and do not release harmful substances.
For PP material, it is widely used in the food industry and is considered to be a food-grade material because it has the following characteristics:1Non-toxic:
PP material does not contain harmful substances and will not cause contamination to food. 2.Chemical Stability:
PP material has good chemical stability and is not easy to react with chemicals in food. 3.High Temperature Resistance:
The PP material can withstand a certain high temperature, and is suitable for heating food or for micro-shooting vertical wave oven heating. However, it is important to note that even food-grade materials need to comply with the appropriate food safety standards and regulations. When selecting and using PP food containers or contact utensils, it is recommended to choose products produced by regular manufacturers and marked with food-grade certification, and use them in accordance with the correct use method and cleaning method.
If you have questions about a specific product or brand of PP material, it is recommended to check the product description and consult the manufacturer or relevant authorities to ensure that it meets the food safety requirements. Hope this helps. If you have any other questions, please feel free to ask.

Hello, according to my understanding, PP material is a kind of polypropylene material, which is usually used to make food containers, tableware, bottles, etc. The PP material itself is in line with the food grade standard, because it does not contain harmful substances and will not contaminate the food. In addition, PP material also has the advantages of good heat resistance, cold resistance, corrosion resistance, etc., and is widely used in food packaging and manufacturing.
It should be noted that although the PP material itself meets the food grade standard, if other chemicals are added during the production process, its food grade safety may be affected. Therefore, when buying PP products, it is recommended to choose products produced by regular manufacturers and check the relevant quality inspection reports to ensure that they meet food-grade standards. In addition to food packaging and manufacturing, PP has many other applications.
For example, it can be used to make auto parts, medical devices, household items, etc. Overall, PP is a very practical material with a wide range of application prospects.
Food-grade plastics are produced under purified conditions.
There should not be many manufacturers of food-grade stainless steel pipes, and it is generally Angang Masteel to find a big brand.
