Products Description
PP board is a homogeneous plastic sheet manufactured with polypropylene as the core raw material. It has a uniform, dense structure and a smooth, clean surface free of impurities and bubbles. It offers excellent chemical corrosion resistance and can maintain stable performance during long-term service under common acid and alkali working conditions. Non-toxic and odorless with balanced physical properties, PP board supports various secondary processing operations including cutting, hot bending and welding. It is widely used in chemical anti-corrosion, environmental protection equipment, food packaging and many other fields as a fundamental engineering plastic sheet that combines practicality and cost-effectiveness.
Product Advantages
Strong corrosion resistance
It provides good resistance to most common acids, alkalis and salts and resists aging or damage caused by erosion from chemical media.
Lightweight for easy handling
Featuring low material density, PP board weighs much less than metal sheets of the same area, making transportation and on-site installation effortless.
Excellent processability
It is compatible with common secondary processing methods such as cutting, hot bending and hot melt welding. Shaping can be completed without special equipment.
Stable weather resistance
When used indoors or outdoors under normal conditions for extended periods, it is not prone to obvious aging issues including yellowing, embrittlement or cracking.
Precautions
Prohibition of over-temperature operation
Do not use the sheet for long periods at temperatures far exceeding its material tolerance, as this may cause softening and deformation and reduce structural strength.
Prohibition of strong media contact
Ordinary sheets without special modification shall not be exposed to strong oxidizing agents and other special chemical media for long periods to prevent rapid erosion.
Prohibition of impact by sharp heavy objects
Avoid sharp heavy objects falling directly onto the board surface from height. Such impacts may lead to irreversible damage such as local cracks and perforation.
Prohibition of excessive load bearing
Do not subject the sheet to long-term concentrated pressure far exceeding its designed load to prevent irreversible indentation and deformation.
Working Principle
Polypropylene resin serves as the base raw material. PP board is uniformly formed in a molten state through plasticizing extrusion or calendering processes. After cooling and setting, a homogeneous sheet with evenly arranged internal molecules is produced. Leveraging the stable molecular structure of polypropylene, the sheet withstands corrosion from most chemical media while retaining good physical ductility and structural strength to meet usage requirements across various scenarios.
Instructions for Use
Cut the sheet with dedicated plastic cutting tools. Control the feed speed during cutting to prevent edge chipping on the board surface.
Heat the bending area evenly during hot bending. Bend the sheet slowly only after it fully softens, and hold the shape until cooling and setting.
Keep both sides of the weld clean and free of oil stains during hot melt welding. Properly control welding temperature and torch travel speed to guarantee weld strength.
Reserve reasonable gaps for thermal expansion and contraction during sheet installation to avoid arching and deformation caused by ambient temperature changes.
Wipe the surface with a soft cloth and neutral detergent for routine cleaning. Do not scratch the board surface with sharp, hard objects.
FAQ
Q: Will PP board age rapidly when used outdoors under direct sunlight for a long time?
A: Weather-resistant modified components can be added as required to greatly improve outdoor anti-aging performance and accommodate long-term open-air use.
Q: Is it difficult to perform subsequent welding processing on PP board?
A: PP material features excellent hot melt welding performance. Splicing can be completed with standard plastic welding guns, and the welds are firm and resistant to cracking.
