Category B
Main characteristics: 

high strength properties: 70–80 MPa (yieldstress, tensile strength)
high toughness (notched Charpy): 8 kJ/m2 – does not break,
good sliding properties : m = 0,25–0,45 (dry sliding on smoothed and ground steel),
wide temperature range for application: from: –50°C to +120°C,
high hardness (Rockwell): M 86 – M 90,
good fatigue strength and damping capability,
does not expand in the presence of moisture, the POM C version can even be used under water up to 80°C,
can be readily cut using automatic machines, as well
density: 1,4 kg/dm3

Basic grade: 
POM C (Polioximetilén ko-polimer) POM H (Polioximetilén homo-polimer)
Special grade: 
In the case of the copolymer versions, a PTFE composite version is available with TF notation to ensure better sliding and wear behavior, 25% glass fiber reinforcement is also available with GF 25 notation to improve dimensional stability, as well as an electrically conducting version with ELS notation.
Main areas of use: 
Dimensionally stable, precision tools, gears with small modules; valve seatings; springs; sliding elements; control cams; insulating elements in electrical industry; machine parts in constant contact with water up to 80°C in the case of POM C; rollers; bonding elements, etc.
Machining technology: 

Cutting (turning, milling, drilling, reaming, sawing): these plastics have the best cutting properties. Traditional metalworking – or in certain cases, woodworking tools – carbon steel, rapid steel, hard metal, diamond can be used in sharp design. Cooling is recommended, which allows high cutting rates e. g. v = 200–500 m/min for turning, v = 200–400 m/min for milling, v = 50–100 m/min for drilling.
Adhesive bonding and welding: feasible but not suggested.

DOCACETAL (POM - Polyoxymethylene) Products

DOCACETAL C

Extruded rods, Plates, tubes

Color: 
white, black, blue, red, yellow, green

The extruded, unfilled copolymer version among polyoxymethylenes. This type of POM has a better resistance to heat ageing than POM-H, and it is resistant to hydrolysis and strong bases, as well. Available colors in limited dimension: blue, yellow, green, red.

DOCACETAL C ELS

Extruded rods, Plates

Color: 
black

Due to the conducting filler material in the basic POM C matrix structure, this product can conduct electrical charges. In comparison with “natural” POM C, the volume and surface resistance of the product is smaller by four – five degrees of magnitude.

DOCACETAL C Esd

Extruded rods, Plates

Color: 
natural (beige)

Due to the conducting filler material in the basic POM C matrix structure, this product can conduct electrical charges. In comparison with "natural" POM C, the surface and volume resistance of the product is smaller by three – four degrees of magnitude.

DOCACETAL C GF25

Extruded rods, Plates

Color: 
natural, black

Due to the glass fiber filling, the mechanical characteristics of POM C are different. The product is more rigid and has better dimensional stability than the “natural” version.

DOCACETAL C ID

Extruded rods, Plates

Color: 
grey, blue

Inductively detectable. POM C base matrix with detectable filler. Good toughness and strength. Good resistance to cleaning agents.

DOCACETAL C MT

Extruded rods, Plates

Color: 
black, blue, green, yellow, red

Special POM C used for medical technology. Very good sliding and abrasion behaviour. Resistant to organic solvents. Resistant to common sterilization methods and cleaning agents.

DOCACETAL C PE

Extruded rods, Plates

Color: 
blue

PE additives ensure excellent sliding properties and improved abrasion resistance.

DOCACETAL H

Extruded rods, Plates

Color: 
white, black

This homopolymer version has greater mechanical strength, rigidity, smaller thermal expansion and better wear resistance than POM-C, but is not as readily usable in watery, warm medium.

DOCACETAL H TF

Extruded rods, Plates

Color: 
natural

PTFE-filled POM-H. Due to the filling material, its characteristics are different from those of the POM-C and POM-H base materials. Due to the PTFE content, it is softer and not as rigid. Conversely, its sliding and wear properties are excellent. Even in the event of large loads and small speeds, sliding without “stick-slip” can be achieved.
