Texto del producto
Chemical abbreviation according to ISO 1043-1: POM Molding compound ISO 29988- POM-K, M-GNR, 03-002 POM copolymer Standard-Injection molding type with high rigidity, hardness and toughness; good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation. Monomers and additives are listed in EU-Regulation (EU) 10/2011 FDA compliant according to 21 CFR 177.2470 .Burning rate ISO 3795 and FMVSS 302 < 75 mm/min for a thickness more than 1 mm. Ranges of applications: automotive engineering, precision engineering, electric and electronical industry, domestic appliances. FDA = Food and Drug Administration (USA) FMVSS = Federal Motor Vehicle Safety Standard (USA) UL = Underwriters Laboratories (USA).
ECO-B: Hostaform ECO-B is a POM-Copolymer with the same properties and performance as standard grades but produced with sustainability in mind. Using a mass-balance approach, biogenic feedstocks are used to offset the use of fossil-based raw materials and decrease greenhouse gas emissions. The process is audited and certified according to the ISCC Plus mass balance approach.

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

Conditioning e.g. moisturizing is not necessary.

Max. Water content 0,2 %
Standard extruders with grooved feed zone and short compression
screws (minimum 25 D) will fit.

Melt temperature 180-190 °C
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
