PTFE
Polytetrafluoroethylene (PTFE), also known as Teflon, is a versatile plastic material with exceptional properties. It is chemically resistant, non-stick, and can withstand high temperatures (-200°C to +260°C). PTFE is commonly used in industries such as chemical processing, food processing, electrical engineering, automotive, and medical due to its unique combination of properties.
Properties
l Resistant to low and high temperatures (-200°C ~+260°C)
l Non-stickiness, low water absorption
l Non-flammable, corrosion resistance
l Oxidation resistance
Applications
l Chemical industry: corrosion-resistant equipment
l Electronics and electrical industry: insulation materials
l Medical devices: biocompatible and antimicrobial materials
l Aerospace industry: lightweight and corrosion-resistant components
l Hydraulic and pneumatic fields: sealing materials.
