Product Texts
Chemical abbreviation according to ISO 1043-1: POM
Molding compound ISO 9988- POM-K, M-GNS, 01-001

POM copolymer

Stiff-flowing type for injection molding and extrusion, modified
with (R) GUR (PE-UHMW); good chemical resistance to solvents, fuel
and strong alkalis as well as good hydrolysis resistance; high
resistance to thermal and oxidative degradation; with GUR (PE-UHMW)
modified extrusion type, therefore very good lubricating properties.

Burning rate ISO 3795 and FMVSS 302 < 100 mm/min for a thickness
more than 1 mm.

Ranges of applications: For injection molding parts and
semi-finished products with higher requirements on lubricating
properties.

PREPROCESSING

General drying is not necessary due to low moisture absorption of
the resin.

In case of bad storage conditions (water contact or condensed water)
the use of a recirculating air dryer (100 to 120 °C / max. 40 mm
layer / 3 to 6 hours) is recommended.

Max. Water content 0,2 %



PROCESSING

Standard injection moulding machines with three phase (15 to 25 D)
plasticating screws will fit.

Melt tempera ture 190-230 °C
Mould temperature 80-120 °C

POSTPROCESSING

Conditioning e.g. moisturizing is not necessary.
Film extrusion

layer / 3 to 6 hours) is recommended.

Max. Water content 0,2 %




PROCESSING

Standard extruders with grooved feed zone and short compression
screws (minimum 25 D) will fit.

Melt temperature 180-190 °C




POSTPROCESSING

Conditioning e.g. moisturizing is not necessary.

In case of very thick wall thickness profiles after-annealing it is
recommended to reduce internal stress.

Annealing temperature 130-140 °C
Annealing time 10 min/mm thickness
