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.
PA nylon as a large amount of Engineering plastics. Widely used in machinery, electrical appliances, textile equipment, chemical equipment, aviation and other fields. Become an indispensable structural material in all walks of life, the main features are as follows:1. excellent mechanical properties. High mechanical strength and good toughness.2. excellent heat resistance. Such as nylon 46, high crystallinity Nylon high thermal deformation temperature, can be used at 150 degrees Celsius for a long time. PA66 after glass fiber reinforcement, its thermal deformation temperature above 250 degrees celsius.3. excellent electrical insulation performance. Nylon has high volume resistance and high breakdown resistance. It is an excellent insulating material for electrical and electrical equipment.4. self lubrication, good friction resistance. Nylon has a good self lubrication, small friction coefficient, so as to drive parts, long service life.5. excellent weather resistance.
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
