In order to ensure the good bearing capacity and beauty of luggage, luggage often uses some materials such as partitions and bottom plates with different shapes.
Because these plates are placed inside the bag, it is difficult to see after the finished product is made, so some users often can not figure out, of course, in addition to the most common cardboard, what will be used?
Today, I will give you a brief introduction to several other commonly used materials: 1. PE board :(Pe board English abbreviation): PE (
Polyethylene polyester abbreviation)
It is a kind of petroleum extract, and PE board is formed by high-temperature heating and pressing PE particles through professional production equipment.
It has the characteristics of light specific gravity, good softness and strong water resistance, and is safe to acid and alkali. The raw material is polyethylene. Specific gravity is 0. 95-0. 96, molding is easy to change. Flammability. 2. Pp board :(Pp board abbreviation): PP (
Polypropylene Polypropylene abbreviation)The particles are heated and pressed out for molding.
It has light specific gravity, good water resistance and heat resistance, and the raw material is polypropylene. Specific gravity is 0. 90-0.
92, the material is hard, not easy to form, and the melting point is low. The lightest plastic, low temperature impact resistance is weak. The thermal deformation temperature is 127-182 degrees per square CM by 4. 6KG deformation. Flammability. 3. ABS board: ABS (
Acrylonitrile butadiene styrene English abbreviation)Acrylonitrile-Butadiene-Styrene copolymer. The material is heavy. Easy to form, easy to burst. Specific gravity is 1. 04.
ABS board is a new material in the board industry.
Its full name is Acrylonitrile/butadiene/styrene copolymer plate.
It organically unifies various properties of PS, SAN and BS, and has excellent mechanical properties of toughness, hardness and stiffness balance. 4. PVC board: PVC (
Polyvinyl chloride abbreviation)PVC specific gravity is 1.
4, affordable, easy to form, easy to deform when heated.
PVC board is a board made of PVC as raw material with honeycomb mesh structure in cross section.
It is a kind of vacuum suction plastic film, which is used for surface packaging of various panels. Therefore, it is also called Decorative Film and adhesive film, and is used in many industries such as building materials, packaging, medicine, etc.
Among them, the building materials industry accounts for the largest proportion, 60, followed by the packaging industry, as well as several other small-scale applications.
According to the degree of hardness, it can be divided into soft PVC and hard PVC.
According to the production process, it can be divided into PVC crust foaming board and PVC free foaming board.
