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.


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.


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.


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℃.
