What are PTFE Lined Caps?
PTFE lined caps are an innovative type of closure cap that is used in a variety of industries. The caps are made from a combination of plastic and metal and are lined with a thin layer of PTFE (polytetrafluoroethylene) material – a synthetic fluoropolymer of tetrafluoroethylene.
PTFE is an extremely durable, non-stick material that is resistant to acids, alkalis, solvents, and high temperatures, suited perfectly for a wide variety of industries such as food processing, pharmaceuticals, chemical processing and laboratory testing. They are often used in the food and pharmaceutical industries, where they are used to ensure the purity and safety of products.
Why Use PTFE?
The use of PTFE lined caps is especially advantageous when capping containers with volatile liquids or those that need to be stored at high temperatures. This plastic-like material is extremely resistant to corrosion and has a low coefficient of friction.
The PTFE lining provides an extra layer of protection from the corrosive effects of the liquid, and it also prevents the container from becoming too hot. This makes it beneficial for use in laboratories and other environments where chemicals are stored and used. This type of lining also serves to create a seal that is completely resistant to any leakage, making it a great choice for sealing off containers and bottles.
PTFE is an industry standard for lining caps, as it can provide a secure seal without causing wear on the container or its contents. This material also has excellent thermal stability and resistance to most chemicals, making it an ideal choice for containers exposed to harsh conditions. These types of caps are also used in laboratory testing since they provide a reliable seal that prevents leakage of hazardous materials.
