Q: Is plastic bucket and plastic bottle the same raw material?: When the number of the triangle in the bottom of the plastic barrel is 5, the main component of this kind of plastic barrel is polypropylene, or PP. The melting point of this kind of plastic barrel is relatively high, reaching 167 degrees centigrade, and can be recycled after cleaning. Compared to PE plastic barrels, PP plastic barrels of heat resistance slightly better, but the higher temperature there is the risk of softening and melting, use should avoid high temperature.

Q: What material is the disc made of, metal or plastic?: The CD disk has a substrate thickness of 1.2mm, a diameter of 120mm, a hole in the middle, and a circular shape. It is the shape of the disc. The reason why the disk can be taken at will depends mainly on the hardness of the substrate.

Q: Plastic PPT30S add what material will increase hardness?: Commonly used talc and calcium carbonate increase the flexural modulus rather than the surface hardness. To increase surface hardness, a nucleating agent can be used. Moreover, talc and calcium carbonate can not be added to the injection molding, you must use the pumping equipment.

Q: What is the material of plastic flat screen?: Widely used in aquaculture, poultry farming, sericulture, civil construction, aquaculture, garden care, keep the field of railway and highway subgrade reinforcement, etc., can also be used for mattress, sofa cushion, car cushion, which is characterized by low cost, long service life.Material: high density low pressure polyethylene (PE), polypropylene (PP), ABS plastic particles.Colors: black, white, orchid, green, yellow, red and so on.

Q: What can be added to the PP plastic material to prevent light transmission?: Join the black color on the line! Plastic is black to prevent light from passing through

Q: What is Ms plastic material?: The utility model has the advantages of good transparency, optical property, low moisture absorption, good weather resistance, easy processing, and residual stress of formed products... Other characteristics. Moreover, the proportion of MS resin is lower than acrylic, and the cost is cheaper.General injection molding and extrusion molding, transparent to acrylic resin (PMMA)

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

Q: What plastic material is resistant to high temperature?: High temperature resistant plastic material:PPS: (PPS)Polyphenylene sulfide (abbreviated as PPS) is a new type of high performance thermoplastic resin. It has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame resistance, good thermal stability and good electrical performance. It is widely used in the fields of electronics, automobile, machinery and chemical engineering

Q: PVC what is the difference between raw and recycled raw materials?: Raw raw materials, such as rubber oil from rubber trees, are extracted from recycled products and recycled materials are recycled materials.

Q: What are the criteria for the classification of plastic materials at injection molding and extrusion?: Plastic material is injection molding or extrusion grade, there is no standard, but there is an applicable reference value, that is, the material "melt flow rate" value.
