PTFE Sheet (Polytetrafluoroethylene Sheet) is a high-performance engineering plastic known for its outstanding properties, such as high temperature resistance, corrosion resistance, electrical insulation, and low friction coefficient. It is widely used in demanding working environments.
Characteristics of PTFE Sheets:
- High Temperature Resistance: PTFE sheets can withstand extreme temperatures, with a working temperature of up to 260°C (short-term up to 300°C), making them suitable for high-temperature environments.
- Excellent Chemical Stability: PTFE is highly resistant to most chemicals, solvents, acids, and alkalis, making it widely used in the chemical industry.
- Low Friction Coefficient: PTFE has one of the lowest friction coefficients of all solid materials, making it ideal for applications that require reduced friction and wear.
- Electrical Insulation: PTFE has excellent electrical insulating properties, making it suitable for use in electrical equipment where high-voltage insulation is needed.
- Resistance to Aging: PTFE sheets do not easily age over time, maintaining a long service life.
Applications:
- Chemical Industry: Used for corrosion-resistant seals, pipe linings, and reactor linings.
- Electrical Industry: Used for cable insulation, electronic component insulation, etc.
- Mechanical Industry: Used as lubricating materials, sealing materials, gaskets, etc.
- Food and Medical Industries: Used for linings in food processing machinery and sealing components.
Specifications:
- Dimensions: Common thicknesses include 2mm, 3mm, 5mm, 10mm, with widths typically ranging from 1 meter to 1.5 meters, and lengths can be customized.
- Color: Typically white, but can be customized in other colors.
- Grades: Available in standard, food-grade, medical-grade, and other specialized grades.
Types of PTFE Sheets:
- Calendered Sheets: Made using calendering process, suitable for most general applications.
- Extruded Sheets: Made using the extrusion process, ideal for custom sizes and thicknesses.
- Filled Sheets: Enhanced with materials like fiberglass or carbon fiber to improve mechanical properties.
This product is known for its durability and versatility in harsh environments, making it a preferred material in a wide range of industrial applications.
