Q:How many kinds of plastic raw materials are there? How to distinguish them?

Classification, composition and characteristics of plasticsPlastic is a synthetic polymer material widely used, in our daily life. From the plastic products meet the eye everywhere after we get up to use the toilet articles, the breakfast dishes, to work with the rest of the stationery, with cushions, mattresses, and TV, washing machine, computer shell, and the night bring us all the other light lamps......

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

In addition, the bag color and performance requirements are not high, you can choose recycled polyethylene. Plastic can be recycled, because of the repeated use of processing, non-toxic, tasteless new plastic become cloudy, less than the original hygiene and color requirements. But this plastic bag is made from recycled material, which is environmentally friendly, and the price is 10% to 50% lower than that of the new material bag

Q:What is the specific material for plastic pallets?

Plastic pallets vary greatly in price, and cheap plastic pallets are made of recycled plastic waste after processing;There is to see the pallet bearing, and see if it is necessary to strengthen the steel bar, if the reinforcement of the bearing, certainly no problem, the price will be relatively high;Plastic tray overall is good, easy to clean, light weight; purchase well, choose a few suggestions tray manufacturers, so that they were bidding competition, so the price can also press down some

Q:What material is the disc made of, metal or plastic?

The compact disk is the carrier of functional structures (such as grooves, etc.), and its material is polycarbonate (PC), which has excellent impact toughness, large temperature range, good dimensional stability, weatherability and non toxicity.

Q:What are the materials for making plastic buckets? How many are there?

Any theory can be made of plastic barrel type container, but for performance and cost considerations, the vast majority of plastic barrels are polyethylene or polypropylene products, drinking machine bucket is the use of polycarbonate (PC). The specific use of what material, to see what you plan to install.

Q:What are the plastic raw materials for this purpose?

Plastic classification, composition and characteristics, plastic is a widely used synthetic polymer materials, in our daily life, plastic products abound.

Q:What kind of material is the raw material of plastic pipes?

The raw material of plastic pipe is mainly based on the plastic tube type, type, polyethylene plastic pipe (PE) is the raw material of ethylene, polyvinyl chloride (PVC) material is polyvinyl chloride, polypropylene pipe (PB) is the raw material propylene.

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:What are the bulk density, size and moisture content of the general plastic material?

Among them, the mass of the material has nothing to do with the particle size, but the larger particles have larger volume due to the presence of more voids between the particles. Small particles (powder) to the general packing is very tight, so the smaller bulk density.

Q:What are the plastic raw materials?

This polymer is made up of many smaller and simpler molecules made of covalent bonds. There are many kinds of polymers, one is to change the Prajna heat to classification, it can be divided into two categories.
