Q:What are the raw materials needed for producing plastic hair dryer shell and flashlight shell?

Water absorbency. Nylon has high water absorption, and saturated water can reach more than 3%. To a certain extent, the dimensional stability of the parts is affected

Q:What are plastic materials extracted from?

Plastic is made of petroleum or natural gas as raw material, through refining, cracking into a variety of petrochemical raw materials (monomer), and then through polymerization (adding polymerization or condensation polymerization) derived from high polymer resin.

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.

Q:PE plastic bellows raw material formula (PE and PP ratio, as well as other filling)?

PP and PE plastic corrugated pipe in the role of the following two: 1, PP material can reduce the production of pipe, HDPE than PP pipe grade market sales price higher, the production of HDPE pipeline adding appropriate amount of PP, for the reduction of raw materials

Q:What can recycled plastics do?

Plastic has good processability, easy to shape, such as: blow, extrusion, pressure, easy cutting, easy welding. In daily life there are many plastics can granulation, such as waste food bags, sandals, wire, plate, agricultural film, pipe, barrels, pots, and packaged with all kinds of waste plastic products can be repeatedly processing, production of plastic raw materials, through special process and formula for making machine parts and components; the system can be used for water, farm machinery, packing bag, cement bag;

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

Yes, but the raw material suppliers have already divided the ingredients into food grade, and they will be used in non food occasions to contain substances harmful to the body

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

Plastic products are divided into: injection molding, blow molding, spray molding, blister, and die casting. Plastic material is oil. It must be done at a high temperature. The mold you call is usually steel.

Q:ABS plastic storage conditions

Plastic materials generally react with light and oxygen for a long time to become yellow and brittle

Q:How many kinds of raw materials are there for blowing plastic bottles?

Plastic bottles are made of polyethylene or polypropylene and added a variety of organic solvents. Plastic bottles are widely used in polyester (PET), polyethylene (PE), polypropylene (PP) as raw material, add the corresponding organic solvent after high-temperature heating, the plastic mold by blow molding, extrusion blow or injection molding of plastic containers.

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

The bulk density has something to do with particle size. The larger the particle, the smaller the bulk density of the same composition. This is because the accumulation of material quality, material bulk density = space volume. The bulk density is pseudo density.
