Docaflon PTFE

Docaflon (PTFE - polytetrafluoroethylene) Docaflon (PFA - perfluoralkoxi copolymer) Docaflon (FEP – tetrafluorethylene-hexafluorpropylene) Docaflon (MFA – modified fluoroalkoxy)
Category B
Main characteristics: 

tensile strength: 16–25 MPa,
extremely good chemical stability,
good surface-release capability,
machinable,
wide temperature range for application: from -200°C to +260-300°C,
hardness (Rockwell): D 50 – D 75,
good damping capability, toughness,
low friction coefficient,
physiologically inert, it can come in contact with food and medicine,
good electrical insulating capability in wet medium, as well,
density: 2,2 – 2,4 kg/dm3

Basic grade: 
PTFE semi-finished products in extruded, molded/pressed, split, scraped design.
Special grade: 
They also manufacture PTFE products with 25 % glass fiber reinforcement to increase accuracy to size and strength and with 25 % carbon content to increase wear-resistance and strength. Furthermore, certain profiles are available in various colors.
Main areas of use: 
Machine parts in the food, chemical and textile industry, general gaskets, insulating elements, precision elements in instrument manufacturing; medical, pharmaceutical equipment, slide wire, form-release agents, etc.
Machining technology: 

Cutting (turning, milling, drilling, sawing): Traditional metalworking – or in certain cases, woodworking tools – carbon steel, rapid steel, hard metal, diamond can be used in sharp design only. Cooling is recommended, which allows high cutting rates e. g. v = 200–400 m/min for turning and milling, v = 50–100 m/min for drilling.
Adhesive bonding: not suggested.

Docaflon PTFE Products

DOCAFLON FEP

Color: 
natural, translucent

Available only for request. FEP belongs to the melt fusible material family. It has good diffusion coefficients to PTFE. FEP has excellent ductility and wide range of dimensions.

DOCAFLON MFA

Color: 
natural, translucent

Available only for request. Just like FEP it belongs to the melt fusible material family. It has excellent transparency among fluoropolymers. It has excellent chemical resistance.

DOCAFLON PFA

Color: 
natural, translucent

Among the fluoro-polymers PFA has excellent heat stability. Comparing to natural PTFE it has better creep resistance and mechanical properties. Welding is possible. PFA available in thin-walled tubes. Different colours are available.

DOCAFLON PTFE-CG25

Plates
Color: 
black

A version of the “natural” PTFE reinforced with carbon and graphite. It has greater rigidity, dimensional stability, smaller creeping, it is electrically Esd material. Its wear resistance is better than that of “natural” PTFE.

DOCAFLON PTFE-GF25

Plates
Color: 
natural

A version of the natural PTFE reinforced with 25% glass fiber. It has greeter rigidity, dimensional stability and smaller creeping in comparison with the “natural” PTFE.

DOCAFLON PTFE-N

Plates
Color: 
white

Unreinforced, unfilled version. Especially used in positions under small mechanic stress where the objective is resistance to chemicals, lining or small friction. It can be manufactured using various technologies, which influence the size selection.
