PP-Platten, also known as polypropylene sheets, are a type of semi-crystalline plastic material. Compared to polyethylene (PE), PP offers higher strength and a greater melting point, making it more suitable for demanding industrial environments. Commercial PP materials are often modified with 1–4% ethylene or even higher ethylene copolymer content to improve toughness, especially in temperatures above 0°C where homopolymer PP tends to become brittle.
Due to their outstanding chemical resistance, high impact strength, and excellent thermal insulation properties, PP-Platten are used in a wide range of industries. Here's a detailed look at their diverse applications:
1. Chemical and Environmental Equipment
PP-Platten are widely used in:
- Acid and alkali-resistant tanks
- Electroplating equipment
- Solar photovoltaic devices
- Environmental protection systems
- Wastewater and exhaust gas treatment units
- Washing towers
- Dust-free rooms and semiconductor-related equipment
Due to their chemical inertness, PP is also the preferred material for manufacturing plastic water tanks Und thick PP boards used as stamping plates Und press pads.
2. Advertising and Display Boards
Thanks to their lightweight and durable nature, PP-Platten are commonly used for advertising boards Und signage panels, especially in outdoor or semi-permanent installations.
3. Reusable Storage and Packaging Boxes
PP hollow sheets are an ideal material for producing various recyclable storage boxes, including:
- Agricultural fruit and vegetable packaging boxes
- Industrial reusable bins
- Clothing storage containers
- Stationery boxes
These containers are lightweight, moisture-resistant, and cost-effective for repeated use.
4. Industrial Packaging and Protection Boards
In the industrial sector, PP-Platten are used for:
- Wire and cable protective sleeves
- Protective packaging for glass, metal plates, and other delicate goods
- Support sheets, shelving, dividers, and base plates
This usage helps safeguard valuable materials during storage and transport.
5. Construction Site Protection
With growing concern over efficiency and aesthetics in construction projects, PP protection boards have gradually replaced traditional materials like paperboard and plywood. They are commonly used to protect:
- Elevator interiors
- Flooring
- Wall surfaces before final inspection and handover
Their ease of use, reusability, and durability make them ideal for on-site construction protection.
6. Electronics Industry Applications
In high-tech sectors, anti-static and conductive PP sheets play a crucial role. They are used for packaging sensitive components such as:
- IC wafers
- Semiconductor chips
- TFT-LCD panels
- Optoelectronic devices
The goal is to prevent static discharge damage, which can be catastrophic for delicate electronics. PP also finds use in ESD-safe turnover boxes, trays, and liners.
7. Household Appliances and Cold Chain Packaging
PP-Platten are used in the production of components for:
- Washing machines (back panels)
- Refrigerators (insulation layers)
- Cold chain packaging for frozen foods, pharmaceuticals, alcohol, and more
8. Urban and Agricultural Applications
Using PP corrugated sheet production lines, manufacturers can also produce PE hollow sheets for applications such as urban construction partition panels Und greenhouse thermal insulation boards in rural settings.
Abschluss
With properties like chemische Beständigkeit, lightweight structure, high impact tolerance, Und reusability, PP-Platten are proving to be a versatile and cost-effective material across countless industries—from construction and electronics to agriculture and packaging.
