Folhas de HDPE, também conhecido como high-density polyethylene sheets, are thermoplastic materials characterized by high crystallinity and non-polarity. They appear milky white in natural form and exhibit a semi-transparent quality in thin sections. With excellent chemical resistance, durability, and flexibility, Folhas de HDPE have become an indispensable material across multiple industries.
Key Applications of HDPE Sheets
1. Medical and Food Industries
Thanks to their non-toxic, odorless, e chemical-resistant properties, Folhas de HDPE are widely used in:
- Medical component manufacturing
- Sealing parts
- Tábuas de corte
- Food processing components such as star wheels, bushings, guide rails, and conveyor elements
2. Chemical and Environmental Engineering
In chemical plants and environmental protection systems, PEAD is chosen for its excellent resistance to acids, alkalis, and solvents. Applications include:
- Corpos de válvulas, pump housings
- Seals, gaskets, nozzles, filter parts
- Chemical storage tanks and protective linings
3. Transportation and Machinery
Folhas de HDPE are also used in:
- Sliding parts of transport machinery (guides, sliders, base plates)
- Paper-making machines (suction box covers, dewatering elements, bearings)
- Textile machines (connectors, damping parts, guide rails)
4. Construction and Agriculture Equipment
Due to its resistência ao impacto e low moisture absorption, PEAD is ideal for:
- Bulldozer lining boards
- Truck bed linings
- Tractor blade linings
5. Port Machinery and Marine Use
In harsh marine environments, Folhas de HDPE resist wear and corrosion. Common applications include:
- Ship components
- Bridge crane wear pads
- Protective rollers and docking blocks
6. General and Mechanical Engineering
With high tensile strength e abrasion resistance, PEAD components are found in:
- Gears, bushings, clutches
- Sliding pads, brake components
- Hinges, couplings, fasteners
7. Recreational and Sports Equipment
- Ice rink flooring
- Ski sled panels
- Protective frames for sports infrastructure
8. Medical Devices and Prosthetics
Because Folhas de HDPE are biocompatible and easily machinable, they are used in:
- Prosthetic components
- Artificial joints
- External casing for medical equipment
