FAQ

How is plastic material made out?
The main components of plastic resin (in the early stage of coal tar products and calcium carbide carbide, it is used for oil and natural gas products, such as ethylene, propylene, benzene, formaldehyde and urea).
I made of plastic raw materials accessories containing benzene, how to remove the teacher, please enlighten!
Plastic generally does not contain benzene, ah, only polystyrene, ABS and other plastic molecular structure containing benzene ring, is a high polymer. Benzene is an organic solvent, low molecular substances, boiling point is low, very volatile.
Dissolve in 0.3 of the LDPE plastic raw materials what?
Low density polyethylene (Low density polyethylene, referred to as LDPE) is usually based on ethylene monomer in high pressure 98 ~ 294MPa, with oxygen or organic peroxide as initiator, the polymerization of the polymer, the density of 0.910 ~ 0. 9259/cm3. medium density polyethylene (MDPE) density is 0.926 ~ 0.9409/cm3; very low density polyethylene (VLDPE) density below 0.910g/cm3.
What are the raw materials needed for producing plastic hair dryer shell and flashlight shell?
The shell materials are ABS and PAABS material is acrylonitrile (Acrylonitrile), 1, 3- (Butadiene) and styrene butadiene (Styrene) three kinds of graft copolymer monomer, ABS plastic molding temperature is 180-250 DEG C, but preferably not more than 240 DEG C, the resin will be decomposed.
What is the difference between ABS plastic raw materials and recycled materials? Or how to distinguish between raw materials and recycled materials?
Raw material is crude oil refining, renewable materials are garbage recycling, and some will have additives in the regeneration. If it is not cleaned, there may be impurities.
What are the properties of plastic material PS? What are the advantages and disadvantages?
Amorphous material, moisture absorption is small, do not have to be fully dry, not easy to break down, but the coefficient of thermal expansion is large, easy to produce internal stress. Good liquidity, can be used screw or plunger injection molding machine
Plastic raw materials are granular, why not powder?
The powder is too choking! Add water to influence the effect of the product!
What raw materials do plastic color printing plants use?
PEBOPPOPS film, aluminum film and so on, the ink is usually water-based ink, polypropylene ink, etc., different films with different ink.
