Fluoroplastics generally refer to high-performance plastics based on fluorine elements, such as polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), perfluoroalkoxy (PFA), etc. They exhibit excellent high-temperature resistance, corrosion resistance, low friction, and non-stick properties, and are widely used in industries such as chemicals, electricity, electronics, and machinery.
Derong Yuandao PFA fittings are of high-purity semiconductor grade and are certified by SGS.
PTFE (polytetrafluoroethylene) is the most common fluoroplastic, known for its excellent high-temperature and chemical resistance. However, it is difficult to process and can be brittle. PFA (perfluoroalkoxy) is a modified fluoroplastic that offers similar properties to PTFE but is more processable, making it suitable for manufacturing precision components, and it is also more ductile.
Fluoroplastics themselves are generally non-toxic. However, at extremely high temperatures (exceeding 400°C), such as with PTFE, they may decompose and release toxic gases (such as hydrogen fluoride). Therefore, when using these materials, excessive temperatures and direct exposure to flames should be avoided.
Fluoroplastics exhibit excellent long-term stability, especially in harsh environments (high temperature, high pressure, corrosive media, etc.). They typically maintain their superior performance. With proper use, fluoroplastics can last for many years, but they should be regularly inspected for signs of aging or performance degradation.
