Slotted Cheese Head Screw (DIN 84) made of PTFE
 
 

Technical specification

Material: PTFE (polytetrafluoroethylene)

Colour: milky white

Regulations: similar to DIN 84, ISO 1207; conforming to FDA

 

Fastening elements made of PTFE are ideally suitable for constructions under highest thermal and chemical load. Very good coefficient of sliding friction, therefore no sticking. Elements made of PTFE hardly get dirty due to their excellent antiadhesive properties.

Very good chemical resistance

Very high temperature resistance

Very good coefficient of sliding friction

Antiadhesive surface

Suitable for food contact applications

PTFE is extremely resistant to UV and weather, even under extreme climatic conditions

Chemical features:

Universal chemical resistance e.g. to fuming sulfuric and nitric acids, except to molten or dissolved alkali metals, elementary fluorine, perfluorokerosene, chlorinetrifluoride as well as other fluorine compounds that attack the material at high pressures and temperatures.

Material specification:

PTFE is a fluoroplast with excellent resistance to acids, alkalis, solvents and gases.

PTFE has good electrical properties.

PTFE is sterilizable and usable in a temperature range from -200 to +260 °C depending on the degree of mechanical load.

No embrittlement, even when in contact with boiling helium (-269 °C).

PTFE is machinable but bondable only after pretreatment.

PTFE is not resistant to fluorine compounds and molten alkali metals at higher temperatures.
