FAQ

What are the APP of plastic raw materials?

General plastics (polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS, etc.), thermosetting plastics (phenolic resin, epoxy resin, unsaturated polyester, polyurethane, silicone, amino resin, etc.);

What are the raw materials for producing plastic films?

Plastic film raw materials are: PVC, polyethylene, polypropylene, polystyrene and other resins.

What kind of plastic material is used for medical instruments?

According to the use requirements of medical plastics, it is often necessary to make products with surface hydrophilicity, anti coagulation, radiation sterilization and other special functions.

What material do you need for plastic film? Do you use this material?

Or LDPE (high pressure polyethylene). Or a mixture of the two. The bags made of two materials each have their own characteristics, and are chosen according to the purpose and performance of the products. Polyethylene is petrochemical products, prices vary according to crude oil and market conditions every day, at present LDPE (high pressure polyethylene) offer at 13500 yuan. HDPE (low pressure polyethylene) at 11000 yuan up and down.

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.

Characteristics of rigid polyurethane foam made of polyurethane raw material

Characteristics of rigid polyurethane foam:Unique heat insulation performance, saving electricity, high efficiency, environmental protection, light weight, lower load;With excellent waterproof performance, heat preservation, waterproof combination;The design is simple, high efficiency, fast progress, good quality and long service life;No fluorine foaming, suitable for wide environment;

What raw material produces the plastic to the human body not to harm, to the environment does not have the pollution?

Starch plastics containing starch in more than 90%, add other components also can be completely degraded, there are Japan Sumitomo Business Corporation, American Wamer-Lamber company, Italy Ferrizz company claims of success starchier in 90% to 100% of full starch plastics, in (January ~ 1) completely biodegradable without leaving any trace, no pollution, can be used in the manufacture of various containers, bottles, films and garbage bags etc. all starch plastics production principle is that the starch molecular allostent anddisorderly change formed with thermoplastic starch resin, also known as the thermoplastic starch plastics. The molding process can be used in traditional plastic processing equipment. With starch as the potential advantages of development of bio degradable plastics raw materials: starch has biodegradability completely in various environments; plastic in the degradation of starch molecules or after ashing, the formation of two oxygen Carbon gas, without soil or air poison; take appropriate technology to make starch thermoplastic after mechanical properties can reach for manufacturing plastic material; starch is a renewable resource, inexhaustible, pioneering starch utilization is conducive to rural economic development. That is, starch plastics production in China of vast the majority of starch filled plastics, is added in a certain proportion of polymer materials in non biodegradable starch, resulting in the collapse of material physical property through biodegradation of starch, prompted a large number of end groups that exposed to oxidative degradation, but the rest of the "collapse" after the PE, PVC and so on are not always possible degradation the residue in soil, of course, days and months multiplying will cause pollution, so the foreign ownership for such products will be eliminated.

What is the difference between EPS plastic particles and PS? What materials are represented?

PS does not have no foaming agent. It is divided into GPPS (ordinary type) and HIPS (impact type). It is used for injection molding, extrusion, television, telephone shell, cup and so on.The main ingredients are polystyrene.
