Q:What plastic material has great impact resistance?

The ability of metal materials, machinery parts and components to resist impact damage is called impact strength.

Q:What is plastic film material?

You should first say what type of plastic film you are going to make. You should make a bag or make a plastic wrap. The type is different. You should see what determines what material to use, and the plastic film is also divided into many kinds

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

The foaming agents for epoxy resins are two types: physical foaming agents and chemical foaming agents. Physical foaming agents are mainly low boiling liquid, such as three chloro methane (F11), three chlorine, three fluorine ethane (F112), two chlorine, two fluorine methane (F12) and so on. By using the curing heat of the epoxy resin, the liquid with low boiling point is evaporated, and the gas is released, and the products are small in density and low in thermal conductivity. But fluorine hydrocarbons have a damaging effect on the atmosphere and are often used to spray foaming processes. According to the experts of China epoxy resin industry association, toluene and so on can be used as auxiliary foaming agent. In addition to foaming, it also acts as a curing reaction, a heat absorber and a diluent.

Q:Dissolve in 0.3 of the LDPE plastic raw materials what?

However, according to ASTM's D-1248-84, the density range of 0.926 to 0.940 g / cm3 is of medium density polyethylene (MDPE). A new generation of LLDPE expands its density to a plastic body (0.890 to 0.915 g / cubic centimeter) and an elastomer (<0.890 g / cm3). But the American Plastics Industry Association (SPI) and the American Plastics Industry Council (APC) extend the range of LLDPE to plastic bodies, not elastomers. In the 80s of the last century, Union Carbide and Dow Chemical called their early sales of elastomers and elastomers as very low density polyethylene (VLDPE) and ultra low density polyethylene (ULDPE) resins.

Q:What are the properties of plastic material PS? What are the advantages and disadvantages?

High temperature, high mold temperature and low injection pressure should be adopted to prolong the injection time. It is beneficial to reduce internal stress and prevent shrinkage and deformation

Q:What kind of plastic material is used for medical instruments?

Because most monomers and their oligomers are poisonous, medical plastics have strict restrictions on the residues of these substances;

Q:Aluminum Alloy door corner with what plastic raw materials do?

The best use of Ninon or ABS material. The two kinds of materials are both hard and hard to wear. However, these two materials, the higher prices.

Q:What is the disposable transparent plastic cup?

GPPS is generally done, do once thrown away, GPPS advantage is cheap, good transparencyPP material is good food grade, non-toxic, but transparent less than GPPS degree, PP toughness better than GPPS, GPPS crisp

Q:What are the raw materials for producing plastic bowls and cups?

PP, the Chinese name is polypropylene. It is a fine kind of resin developed after nylon. It is a kind of linear polymer with high density, no side chain and high crystallinity. It has excellent comprehensive properties. Not colored, white, translucent, waxy, lighter than polyethylene. Transparency is also better than polyethylene, more rigid than polyethylene.

Q:What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?

Fillers, also called fillers, can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce the cost, and make phenolic plastic one of the cheapest plastics, and can also significantly improve the mechanical strength. Packing can be divided into two kinds of organic fillers and inorganic filler, the former such as wood powder, rags, paper and all kinds of fabric, the latter such as glass fiber, diatomite, asbestos, carbon black.
