F4-1200 Teflon PTFE Film ( Size: 0.1mm to 1.0mm )
F4-1220 Teflon PTFE Sheet ( Size: 1.0mm to 6.0mm )
F4-1230 Molded Teflon PTFE Sheet ( size: 4mm to 100mm )
PTFE has a wide range of practicable temperature from -180°C - +260°C and a wax-like surface to which anything hardly sticks. PTFE has the lowest coefficient of friction of all known solid materials. It has the best electrical properties of all plastics.
Apparent density ………………….. 2.10-2.30 g/cm3
Tensile strength (min) …………….14.0 MPa
Ultimate elongation (min) ………….. 140%
This excellent engineering plastic known as PTFE Sheet is available in thicknesses ranging from 0.25mm thick up to 50mm thick and is generally known as a semi finished plastic, which means that further "finish" machining is expected to create complicated parts.
PTFE Sheet for Low Friction
This exceptional materials has a fantastically low co-efficient of friction and has been described as the most slippery solid material known to man and has friction values which are simular to that of ice, making PTFE Sheet perfect for low friction applications.
PTFE Sheet and High Operating Temperatures
As a high perfomance engineering plastic, PTFE Sheet it has one of the highest operating temperatures of all the engineering plastics and at over plus 250°C few can match this high performance material.
PTFE Sheet for Electrical Resistance
This is one of the best materials to use in environments where high electrical insulation is required and PTFE Sheet materials will outperform most other plastics.
PTFE Sheet for Acid/Chemical Resistance
This is another area where PTFE Sheet excells and offers excellent resistance to both chemical and acid attack and will resist the more aggressive concentrations at higher temperatures.
PTFE Sheet for Low Moisture Absorption
PTFE Sheet has shown to have minimal moisture absorption and provides a platform for more stable components where this high performance enginnering plastic can further outperform other plastics.
PTFE Sheet Machining
Because this is a high performance engineering plastic, PTFE sheet can be a very easy plastic to machine although care must be taken to ensure that this relatively soft material is not damaged and can provide components with excelent finish.
PTFE Sheet Bonding
Although it is difficult to bond PTFE Sheet can be bonded with careful preparations and the correct adhesive , we also recommend consulting an adhesive specialist. |

PTFE has a wide range of practicable temperature from -180°C - +260°C and a wax-like surface to which anything hardly sticks. PTFE has the lowest coefficient of friction of all known solid materials. It has the best electrical properties of all plastics.
Apparent density ………………….. 2.10-2.30 g/cm3
Tensile strength (min) …………….14.0 MPa
Ultimate elongation (min) ………….. 140%
PTFE Rod and Low Friction:
PTFE Rod has a very low co-efficient of friction, in fact PTFE has a friction co-efficient so low that it has made it into the record books for the lowest of any solid material known to man and similar to that of ice.
PTFE Rod for Temperature Extremes:
Another important advantage that PTFE Rod has is its remarkable performance at high temperature extremes. PTFE Rod is one of the very few plastics that can withstand extreme high temperatures of over plus 250°C and PTFE can also withstand extreme low temperatures of well under plus 200°C. This makes PTFE pretty unique amongst other engineering plastic materials.
PTFE Rod for Electrical Insulation:
If you are looking for high levels of electrical insulation, PTFE Rod is one of the best materials out there, although other materials such as PVC Rod are more popular, it can not perform at the same levels as PTFE Rod and would ultimately fail where PTFE will still provide the performance.
PTFE Rod for Acid and Chemical Resistance:
One of the other important areas where PTFE Rod is excellent is its chemical and acid resistance. This is often overlooked but PTFE can provide excellent high resistance against quite aggressive acids and chemicals at quite high concentrations and at higher temperatures. Although there are materials on the market that are more well known for the application PTFE Rod can offer advantages that some of these other materials can not.
PTFE Rod and Adhesives:
Although PTFE is extremely slippery, there are specialist adhesives produced specifically to bond PTFE to PTFE and also to bond PTFE to other materials. This usually involves a primer which etches the surface of the PTFE Rod to prepare the initial surface and the adhesive in then applied to complete the bonding process. It may be more complicated in terms of having a two part process than other bonding systems but if you require any assistance with adhesives for PTFE Rod,
PTFE Rod Important Details:
There are a few characteristics regarding PTFE that may be helpful to be aware of:
PTFE Rod Bonding:
As mentioned earlier, bonding PTFE Rod can be a little more involved than potentially with some other plastics. |
