PP Hollow Sheet(corrugated sheet/two-wall sheet)


PP hollow sheet is a kind new material of Light weight (hollow structure), non-toxic, pollution-free, waterproof, shockproof, anti-aging, corrosion resistant and colorful.


Application:

PP hollow sheet is widely used in various industries, such as advertising background, stationery materials, industrial packaging, shock proof products, etc.Generally, the most popular product of PP hollow sheet is turnover box, which can classify detachable combination box, finished-product packing box, partition and others.


Thermal property

Polypropylene has good heat resistance, which products can tolerate 100℃ for sterilization. Without external conditions, it is not deformed at 150℃. The melting temperature of PP increased 40% to 50% rather than polyethylene’s, around 160℃-170℃. 100% isotactic polypropylene’s melting point is 176℃.


Mechanical property

Polypropylene has excellent mechanical property because of its high crystallinity and regular structure. The mechanical property of polypropylene are higher than polyethylene. At the same time, the most outstanding property of polypropylene is bending fatigue resistance, commonly known as 100 fold rubber.

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.


Electrical property

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.

Excellent properties of polypropylene:

The relative density is small, which is one of the lightest varieties of plastics.

Good mechanical properties. Besides impact resistance, other mechanical properties are better than polyethylene, molding processing performance is also better than polyethylene.

It has high heat resistance which can be used continuously at 110-120 ℃.

Good chemical properties. don’t absorb water and don’t react with most chemicals.

Pure material and non-toxic.

Good electrical insulation.

The transparency of polypropylene products is better than polyethylene products’.
