TEFLON
Teflon: Superior Insulation & Safety
PRODUCTS > TEFLON
WHAT IS TEFLON?
Teflon, a brand name for PTFE (polytetrafluoroethylene), revolutionized material science with its discovery in 1938. This fluoropolymer is celebrated for its remarkable properties, including resistance to high temperatures and chemicals, making it indispensable across various industries.
Its low-friction surface is not just a staple in cookware but also finds use in electrical insulation, chemical tank liners, and more. With the ability to perform under extreme conditions — from -240°C to 260°C — it ensures reliability in even the most demanding applications.
Axim Mica’s product line harnesses these exceptional qualities to offer solutions that meet the highest standards of performance and safety.

TYPES OF TEFLON PRODUCTS
At Axim Mica, our Teflon lineup is designed to meet a spectrum of industrial needs, highlighting two key variations that exemplify the versatility and performance of our offerings:
- Teflon PFA (Perfluoroalkoxy alkanes): Known for its superior ability to withstand continuous high temperatures and aggressive chemical environments, Teflon PFA is the material of choice for applications requiring utmost reliability and cleanliness. Its exceptional clarity and flexibility make it ideal for use in semiconductor, pharmaceutical, and laboratory settings.
- Teflon PTFE (Polytetrafluoroethylene): This is the original Teflon material that boasts remarkable chemical inertness, virtually universal resistance to chemicals, and a wide temperature service range. Teflon PTFE’s unparalleled low friction coefficient and non-stick properties are exploited in everything from cookware coatings to aerospace components.
BENEFITS & ADVANTAGES OF TEFLON
- Superior Chemical Resistance: Ensures long-lasting performance without degradation, even in the most corrosive environments, safeguarding your investments and processes.
- Exceptional Heat Resistance: It’s ability to withstand extreme temperatures means components remain functional and reliable, even under thermal stress, ensuring safety and integrity.
- Low Friction Coefficient: Results in smoother operations with reduced wear and tear on moving parts, leading to lower maintenance costs and extended equipment life.
- Electrical Insulation: Provides unmatched dielectric properties, essential for electrical and electronic applications, enhancing safety and preventing malfunctions.
- Non-Stick Surface: Simplifies cleaning and maintenance, particularly in cookware and processing equipment, saving time and improving hygiene.
HOW TEFLON IS MADE
- Polymerization: The process begins with the polymerization of tetrafluoroethylene (TFE) gas, under controlled conditions, producing a fine, white powder – the base PTFE resin.
- Mixing: This resin is then mixed with a lubricant to facilitate molding; the mixture’s ratio is crucial for maintaining Teflon’s unique properties.
- Pre-forming: The mixture undergoes pre-forming under pressure to shape it into a moldable form without initiating the sintering process.
- Sintering: The pre-formed material is heated to high temperatures, causing the PTFE particles to fuse in a controlled sintering process, solidifying the material and enhancing its properties.
- Cooling & Finishing: Finally, it’s slowly cooled and then undergoes finishing processes, including cutting and shaping into the final product, ready for a wide range of applications.

FAQs
Teflon is found in a wide variety of products, including non-stick cookware, insulation for electrical wires, performance fabrics, bearings, seals, and many industrial coatings to mitigate friction and chemical exposure.
Currently, Teflon’s applications extend beyond cookware to aerospace, automotive, electronics, and medical devices, thanks to its excellent heat resistance, chemical inertness, and low friction properties.
Products containing Teflon typically feature it in their specifications or marketing materials. For cookware and textiles, look for labels indicating “PTFE” or the Teflon brand. In industrial products, consult the manufacturer’s data.
Teflon functions primarily to provide a non-reactive, low-friction surface that resists high temperatures and chemicals. This makes it ideal for applications requiring smooth operation, durability, and protection against harsh conditions.
