PVC film

1. Characteristics of PP material

 PP plastic, chemical name: polypropylene. English name: Ploypropylene (PP for short), specific gravity: 0 92-0.95 g/cm3, molding shrinkage: 1.0 -2.5%, molding temperature: 160-200℃. It is a kind of high density, no side chain, high crystallinity The linear polymer has excellent comprehensive properties. When uncolored, it is white translucent waxy. Compared with polyethylene, polypropylene is lighter, more transparent, and hard.

 

2. Features
 The density is small, the strength, rigidity, hardness and heat resistance are better than low-pressure polyethylene. It can be used at about 100°C. It has good electrical properties and high-frequency insulation. It is not affected by humidity, but it becomes brittle, non-wearing, Easy to age, suitable for making general mechanical parts, corrosion-resistant parts and insulating parts.

 

3. Thermoplasticity
 Polypropylene is a kind of thermoplastic polymer (thermoplastic: refers to a material that can be melted and cooled and then hardened after heating, and can be repeated; polymer: refers to a natural or synthetic compound whose molecule is composed of a series of simple monomers Macromolecules that are repeatedly connected together) are widely used. Even Australian banknotes are made of PP. PP has unusual resistance to chemical solvents, acids and alkalis.

 

4. Purpose
1) The stationery category includes: PP folder, PP business card case, PP briefcase, PP data book, PP page card, PP partition sheet, PP notebook cover, PP book holder, PP writing board, PP wall calendar, PP desk calendar, PP Stationery products such as mouse pads, PP stationery portable boxes, etc.

2) Gift categories include: PP gift box, PP gift bag, PP handbag, PP handbag bottom lining, PP lining, PP glasses display stand, PP tissue box and other packaging.
3) Food categories include: PP placemats, PP coasters, PP bowls, PP candy boxes, PP candy bags, PP wine boxes, PP wine bags, PP cutting boards, etc.
4) Lighting categories include: PP lampshade, PP flame board, PP fireplace reflector.
5) Electronics include: PP electronic interlayer board, PP electronic packaging box, etc.
6) Shoes and clothing categories: PP clothing box, PP clothing line drawing board, PP clothing listing, etc. PP shoe box, PP shoe lining, PP shoe pattern drawing board, etc.
7) Other PP products include: PP supermarket hanger, PP luggage tag, PP road sign, PP drawer, PP raincoat box, PP photo frame, etc.

5. PP physical properties

 Polypropylene is a non-toxic, odorless toy, odorless milky white highly crystalline polymer. Water stability, good surface gloss, easy to color, good heat resistance, stable chemistry, and good insulation.
