Q:What material is the disc made of, metal or plastic?
In general, the substrate is colorless and transparent polycarbonate board, in the entire disc, it is not only the carrier of the groove, but also the physical shell of the whole cd.
Q:How many kinds of raw materials are there for blowing plastic bottles?
Mainly used in beverages, food, pickles, honey, dried fruits, edible oil, agriculture, veterinary drugs and other liquid or solid disposable plastic packaging containers. Plastic bottles are not easy to break, low cost, high transparency, food grade raw materials and so on.
Q:Will plastic raw materials (such as PET, PP, etc.) be made of non-woven fabrics, will certainly contain BPA?
Only PC (polycarbonate) is available.If the customer is not sure, you can take your product to the third party organization testing, prove that you can do without BPA, and ask your supplier to provide inspection reports and guarantee without BPA.
Q:What kind of raw material is plastic hollow board made of?
Plastic hollow board products widely, can produce hollow board turnover box, hollow board, hollow plate knife clapboard, anti-static hollow board, conductive plastic hollow board products. Multi use in electronic products turnover and handling, warehousing and so on. In addition to the production of flame retardant plastic hollow board, plastic plastic hollow board, back board, magnetic refrigerator with black and white writing board, backplane cloth cabinet inside the closet board and other plastic products.
Q:What are the concepts, classifications and distinctions of modified plastics and plastic materials?
Plastic raw material:Concept: the word "plastic" in the word "plastic material" is intended as a material or plastic material that can be arbitrarily shaped into various shapes. In the dictionary is defined as "synthetic or natural polymers as the main component, under certain conditions can plasticization and molding can keep shape, the end product of materials.Classification: (1) according to the characteristics of resin when heating and cooling, classification: 1. Thermosetting plastics, two, thermoplastics(2) according to the classification of plastic use: general plastics, engineering plastics, plastic raw materials
Q:What is the difference between PPA plastic raw material and PP?
PP is the most common bulk material, such as you see the plastic basin, storage box, etc., is PP do, PP's scientific name is polypropylene, regular PP price is now a little more than ten thousand per ton, special modified PP price is slightly expensive.
Q:What does MFI mean in PC material?
The measurement of MI is usually based on the standard method of ASTM D1238. It is the principle of the plastic or resin into the metal sleeve of a fixed inner diameter, and heating the plastic or resin after melting, and then give some load on the piston, the piston on the weight of the molten plastic has been squeezed out from a small hole in the charge, and calculate the weight and squeezed out of plastic. This measuring method, because of the same material, the sleeve barrel inner diameter, load, and temperature are fixed, so in addition to test MI, can also be used for the determination of density, viscosity, and melt shear rate, shear stress... etc.
Q:How about the price of plastic raw materials now?
The downstream continues to be on demand, with little change in demand. There is a more detailed analysis of quotations
Q:What is the essential difference between plastic raw materials and engineering plastics?
Engineering plastics are a type of plastics, as well as general plastics.Like everyday things, what barrels, pots, plastic, etc?.
Q:How many types of plastics are there?
PP: the name for polypropylene, five-star pin, handrails, floor mats and high strength is not necessary connections. Disadvantages: poor wear resistance and low surface hardness.
