EPP is the abbreviation of expanded polypropylene, which is the abbreviation of a new type of foamed plastic.
Performance and application of EPP
EPP has the advantages of light specific gravity, good elasticity, earthquake resistance and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-water absorption, insulation, heat resistance (-40 ~ 130℃), non-toxic and tasteless, and can be recycled at 100%, with almost no degradation in performance. EPP beads can be molded into EPP products with different shapes in the mold of the molding machine.
EPP is widely used in automobiles, such as bumper core, anti-collision block, ceiling and other lining parts, door gasket, headrest, sun visor, etc., which can save fuel consumption and improve the safety factor of occupants.
EPP has been widely used in packaging industry, such as electronic products and medical devices. Especially in the packaging of export products, it has become an irreplaceable packaging for environmental protection. Because of its non-toxicity and high temperature resistance, it is also widely used in food packaging and microwave heating.
EPS
Extensible multi-style
Expandability+polystyrene? Polystyrene is foamed polystyrene, commonly known as polystyrene (EPS).
Mainland people call it foam, Hong Kong people call it styrofoam, Taiwan Province people call it Julong, and plastic is called polystyrene EPS.
characteristic
Julong is made of foamed plastic and has the functions of cushioning, insulation, heat insulation, sound insulation and vibration prevention. All market devices, such as fish shipment, food boxes, electrical products, fire prevention, sound insulation (thermal) materials in the construction industry, and packaging of high-tech products, all depend on Julong, which shows that its functions are infinitely broad.
Recovery of julong waste
If Julong is buried as garbage at will, it will not dissolve even after a hundred years. Otherwise, if Julong burns by itself, it will produce "dioxin" and cause secondary pollution. EPS (polystyrene foam) is an excellent shockproof packaging material with low price and wide application. It has the properties and characteristics of heat insulation, sound insulation, shock prevention, light buffering and easy molding.
EPS (polystyrene foam) can be cut quickly, and its size, specification and shape can be produced and designed according to customers' specific requirements, without the cost of mold opening, and can be replaced at any time according to customers' products to meet customers' different requirements and special designs.
EPS (polystyrene foam) can be processed, shaped and cut, commonly used lining, special cutting board, corner protector, edge protector, etc.
Machine-made EPS (styrofoam) needs to be opened, which is suitable for all kinds of packaging with large demand and complex shape.
Application scope: office furniture, glass products, instruments, stones, gift boxes, handicrafts, construction projects, etc.
"Application scope: household appliances, instruments, electronic products, glass ceramics, travel bags. Craft gifts, and so on. "
Julong is formed in a white vacuum, which has low degradation and great impact on the environment. It is generally forbidden to be used in Japanese and European markets.
Julong (EPS) mechanical equipment:
Sheet forming machine
Vacuum flat forming machine
Vacuum thick plate forming machine
Intermittent starter
polyurethane
Polyurethane material
Polyurethane material is the abbreviation of polyurethane, which is called polyurethane in English and is a kind of polymer material. Polyurethane is a new type of organic polymer material, known as "the fifth largest plastic", and is widely used in many fields of national economy because of its excellent properties. The product application fields involve light industry, chemical industry, electronics, textiles, medical treatment, architecture, building materials, automobiles, national defense, aerospace, aviation and so on.
