PTFE – versatile material with important properties
PTFE (also known by the trade names Teflon, Hostaflon or Fluon) is characterised by a number of extremely useful properties for a wide range of production and processing applications:
- Almost universal chemical resistance
- High temperature resistance
- Excellent sliding properties
- Very good insulation behaviour
- (Almost) completely resistant to unwanted water absorption
PTFE is the high-performance all-rounder for industry
Globally based and active clients and customers from industries such as…
- Automotive
- Chemistry
- Electrical engineering
- Mechanical engineering
- Medical technology
- Pharmacy
- Food
- and many other sectors of the industry
…rely on turned parts and semi-finished products from HEUTE+COMP. All products “Made in Radevormwald” are characterised by high quality. At HEUTE+COMP., new incoming raw materials undergo strict quality testing as part of the production of test specimens. This includes, for example, a test of ball pressure hardness and tensile strength.
PTFE turned parts and semi-finished products in top quality
Based in Radevormwald, North Rhine-Westphalia, the owner-managed company HEUTE+COMP. has been a leading supplier in the production and processing of versatile high-performance plastics for decades. These materials, which are so valuable for a wide range of industrial sectors, include above all
- Polytetrafluoroethylene (PTFE)
- thermoplastic fluoroplastics Perfluoroalkoxy copolymer (PFA)
- Perfluoroethylene propylene (FEP)
- and a variety of different partially fluorinated materials
In addition to the high quality of all products and materials, HEUTE+COMP. is also known for its exceptional consulting expertise: Simply get in touch with us so that we can find the perfect processing solution for your project.
PTFE from the specialist and industry partner
Service and advice for customers, the highest quality standards in development and production, plus a high-performance and versatile material: PTFE solutions from HEUTE+COMP. also help your company to make production and/or processing safer, more efficient and better.
Thanks to its versatile advantages and properties, PTFE can easily fulfil a wide range of individual requirements in industry. Due to the extremely high bonding forces between the fluorine and carbon atoms in the molecular chain, only a few media, including elemental fluorine, can attack the plastic. A list of the media resistance of PTFE and PTFE compounds can be found here.
Thanks to its high temperature resistance, the plastic can also be used at continuous operating temperatures of -250 °C to +260 °C (without mechanical stress). The friction coefficients of PTFE are also almost identical in the static and dynamic range. The dreaded “stick-slip effect”, which increases the breakaway torque when the system starts up, does not occur. Side effect: PTFE construction parts are easy to clean because nothing can stick to them.
PTFE has very good insulation behaviour: The insulation behaviour of PTFE is superior to most other plastics, especially in the high-frequency range (including ultrasound). The specific volume resistance of pure PTFE is 1018 ohms * cm. In addition, the term “water absorption”, which is extremely feared in many industrial applications, is almost a foreign word for polytetrafluoroethylene. Under test conditions, water absorption is less than 0.01%. Some mechanical properties can be found in this table.
When good things can still be improved: PTFE Compunds
Although the plastic, also known as Teflon, is already very versatile: by adding fillers, the plastic can be customised to your application if pure (virginal) polytetrafluoroethylene does not yet meet your high requirements. This can be achieved with different compounds. These are fillers such as bronze, stainless steel, glass fibres or carbon (graphite) and molybdenum disulphide. These fillers – also in appropriate combinations – result in optimum load values for polytetrafluoroethylene. This allows, for example, pressure and wear resistance, hardness and thermal conductivity to be significantly improved. A high level of expertise and state-of-the-art technology at HEUTE+COMP. make it possible, for example, to customise turned parts and semi-finished products to the respective requirements. We offer you the highest possible quality for all our products. Further information: PTFE compounds.
PTFE turned parts – Moving with maximum precision
Parts that rotate are usually important functional components of various products. These can be tiny micro parts for medicine or watch technology, but also larger long turned parts in mechanical engineering, for example. Plastics can be manufactured with high precision (machining technology). Today, this is also made possible by modern CNC (Computerised Numerical Control) technology. At HEUTE+COMP, computer-controlled, modern CNC machines produce PTFE produces turned parts of the highest precision and durability. Extensive experience, especially in the field of machining production processes, predestines HEUTE+COMP. to be a top company in the field of turned parts. Thanks to modern, high-quality lathes and milling machines, we can offer you reliable, precisely fitting turned parts, exactly according to your individual specifications. The material quality of this high-performance material can also be further optimised for turned parts at any time with the help of compounding.
PTFE semi-finished products – High-quality basis for precision products
We offer you our expert advice when selecting semi-finished products. Especially when it comes to the question of which fillers are best suited for the subsequent use of a product. This semi-finished product is particularly suitable as a preliminary product for subsequent customised products due to its very wide range of possible uses. Whether blocks, sheets, profiles or tubes. Semi-finished products of this type are ideal for the production of PTFE seals, for example. We mainly offer glass and carbon as optimising fillers. Strict monitoring of all important work steps is the basis for our high quality standards for material and production.
These are just a few examples of how HEUTE+COMP., an innovative company with a long tradition, can optimise production, processing and other work processes as a partner to industry.
