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:

it replaces some corrugated packaging materials step by step. Now, some domestic enterprises are also developing it for building decoration materials.


PP hollow sheet characteristic:

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. with other charged objects so that causing damage of the parts due to spark. In addition, there are also anti-static plastic sheet, swing box, etc.

2. Advertisement and Decoration: display sign, commodity sign, billboard, light box, window display, etc.


Weather resistance

Polypropylene is very sensitive to ultraviolet radiation. The addition of zinc oxide, dimethyl thiopropionate, carbon black or similar white filler can improve the aging resistance of polypropylene.


Characteristics

Non-toxic; tasteless; low density; can be used at about 100℃. It’s suitable for making general mechanical parts, corrosion-resistant parts and insulating parts because of good dielectric property, moisture proof and high frequency insulation. Common acid and organic solvents have little effect on it so that it can be used in food utensils.

Thermal property

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℃.


Chemical stability

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
