3. Impact-modified PP Sheets
These sheets are enhanced with additional modifiers that improve their impact resistance and toughness, especially in colder temperatures. They are used in various industrial applications where durability is essential.
4. Special-grade PP Sheets
Specialized PP sheets include variations like UV-resistant sheets for outdoor use, flame-retardant PP sheets, and those designed for specific applications like cleanroom environments.
PP Sheets Manufacturing Process
The production of PP sheets involves several steps, with the key process being extrusion. In this process, polypropylene resin is heated and forced through a mold to form a sheet. The sheets are then cooled, trimmed, and cut into the required sizes.
Key Machinery in Production
Extruders: These are used to melt and mold the polypropylene into sheets.
Calendaring Machines: Used to press the sheets to achieve the desired thickness.
Cutting Machines: These ensure the sheets are cut to precise measurements.
Common Applications of PP Sheets
