Q:What are the raw materials of foam plastics and how do they come out?

More bisphenol A epoxy resin, epoxy value of 0.51 ~ 0.22mol/100g. When the viscosity is 25 degrees centigrade, it is 20Pa / S; the viscosity is 130 s at 1Pa.

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:How is plastic material made out?

Some plastics are made up of synthetic resins, with or without additives such as plexiglass and polystyrene. The so-called plastic, in fact, it is a kind of synthetic resin, the shape of the natural resin with pine resin similar, but also because of the chemical strength of the synthesis, and is called plastic.

Q:Main ingredients and formulations of PPR tubes

PP-R (polypropylene, random) tubes are also called type three polypropylene tubes and also called random copolymerized polypropylene tubes or PPR tubes. The main component is polypropylene three. The formula is different for each manufacturer. This ratio requires manufacturers to do experiments many times before they can be certain.

Q:Can PE material be used as food grade plastic?

Plastic film PE the main consumption areas, because of its more and more used in consumption and transportation, the development of the relationship between demand and the overall economic situation is bigger, basically maintain a slightly higher than the national GDP growth, the growth momentum of stable existence of rigid demand. From the flexible packaging film production statistics, since 2006, the average increase rate of 13%, but also confirms the steady growth of plastic film. Another important consumption area of polyethylene is plastic pipe, and its output increases with the pace of urbanization in China, and the increase of municipal pipeline construction projects is increasing. In the next few years, the municipal water supply and drainage, gas pipelines, and urban underground power, communication, sheathing and pipelines will continue to be the focus of development in recent years.

Q:What are the raw materials for making plastics?

1. the main component of plastic raw material is resin2: plastic raw material is made of polymer synthetic resin (polymer) as the main ingredients penetrate various auxiliary materials or additives, in particular temperature, has the plasticity and fluidity under pressure, can be molded into shape and maintain the same shape of material under certain conditions.

Q:What are the APP of plastic raw materials?

Thermosetting plastics (phenolics, epoxy resins, unsaturated polyesters, polyurethanes, silicones, amino resins, etc.);

Q:How are plastic products made? What is the raw material of plastics?

1, simply say, use an injection molding machine to melt the material at high temperatures and then inject the mold into the mold at high pressure.2, raw materials are materials that have not been processed. Plastic raw material is standing (smaller than soybean).Generally ABS, PS, PP, and so on, these materials are not the same.3, melting at high temperatures, and stamping (I haven't seen)4, iron or steel mold, to see what your home appliance plastic parts, what kind of mold is it!

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

2, and 372 organic glass welding good, made of two color plastic parts, and surface chromium plating, spray paint processing3, high impact, high heat resistance, flame retardant, enhanced, transparent and so on.4, liquidity is a little worse than HIPS, better than PMMA, PC and so on, good flexibility.Molding performance 1. amorphous material, medium mobility, moisture absorption, must be fully dry, surface requirements of the plastic parts must be prolonged preheating, drying 80-90 degrees, 3 hours2., should take high material temperature, high mold temperature, but the material temperature is too high, easy to decompose (decomposition temperature is >270 degrees). For the higher precision plastic parts, mold temperature should take 50-60 degrees, for high gloss, heat-resistant plastic parts, mold temperature should take 60-80 degrees

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.
