PP Hollow Sheet(corrugated sheet/two-wall sheet)
Compared with the traditional paperboard products, PP hollow sheet has the advantages of moisture-proof, corrosion resistance and so on; and compared with injection-molding products, environmental PP hollow sheet has the advantages of earthquake resistance, flexible structure design and it is also unnecessary to open injection mould. What’s more, in the way of controlling the raw material, those materials of static-free, electric and other materials can be added in it so that it can have electric, static-free and other characters.
The chemical stability of polypropylene is very good. Apart from being eroded by concentrated sulfuric acid and concentrated nitric acid, polypropylene is relatively stable to other chemical reagents. However, low molecular weight fatty hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften and swell polypropylene. What’s more, its chemical stability is also improved with increasing of crystallinity, so polypropylene is suitable for making all kinds of chemical pipes and fittings, and the corrosion prevention effect is good.
It has high dielectric coefficient and can be used to make heated electrical insulating products with the increase of temperature. Its breakdown voltage is also very high, which is suitable for electrical accessories and so on.
PP hollow sheet characteristic:
non-toxic, odorless; environmental; moisture-proof; corrosion-resistant; light weight, tensile resistance, high strength and other properties;
The surface can be printed or pasted; different colors can be produced according to the demand; by adding flame retardant, the produced hollow sheet of the flame-retardant effect can be extinguished.
The main uses of PP hollow sheet
1. Replace corrugated cardboard, board, metal sheet, etc.
2. Turnover box, spare parts turnover box, food container, beverage container, pesticide packing box, inner packaging of precision instruments, packaging gasket and partitions for electronic components , and transport storage turnover box, etc.
3. Industrial panels, protective packaging of various articles, cushions, shelves, partitions, floor sheet, cross sheet, etc.
Excellent properties of polypropylene:
1.The relative density is small, which is one of the lightest varieties of plastics.
2.Good mechanical properties. Besides impact resistance, other mechanical properties are better than polyethylene, molding processing performance is also better than polyethylene.
3.It has high heat resistance which can be used continuously at 110-120 ℃.
4.Good chemical properties. don’t absorb water and don’t react with most chemicals.
5.Pure material and non-toxic.
6.Good electrical insulation.
7.The transparency of polypropylene products is better than polyethylene products’.
