CELCON M90™ | POM | Unfilled

 

Description

Celcon acetal copolymer grade M90™ is a medium viscosity polymer providing optimum performance in general purpose injection molding and extrusion of thin walled tubing and thin gauge film. This grade provides overall excellent performance in many applications.

 

Chemical abbreviation according to ISO 1043-1: POM

Other Processing

Injection Molding

Standard reciprocating screw injection molding machines with a high compression screw (minimum 3:1 and preferably 4:1) and low back pressure (0.35 Mpa/50 PSI) are favored. Using a low compression screw (I.E. general purpose 2:1 compression ratio) can result in unmelted particles and poor melt homogeneity. Using a high back pressure to make up for a low compression ratio may lead to excessive shear heating and deterioration of the material.

 

Melt Temperature: Preferred range 182-199℃ (360-390℉). Melt temperature should never exceed 230℃ (450℉).

 

Mold Surface Temperature: Preferred range 82-93℃ (180-200℉) especially with wall thickness less than 1.5 mm (0.060 in.). May require mold temperature as high as 120℃ (250℉) to reproduce mold surface or to assure minimal molded in stress. Wall thickness greater than 3mm (1/8 in.) may use a cooler (65℃/150℉) mold surface temperature and wall thickness over 6mm (1/4 in.) may use a cold mold surface down to 25℃ (80℉). In general, mold surface temperatures lower than 82℃ (180℉) may hinder weld line formation and produce a hazy surface or a surface with flow lines, pits and other included defects that can hinder part performance.

 

Film Extrusion

Standard extruders with a length to diameter ratio of at least 20:1 are recommended. The screw should be a high compression ratio of at least 3:1 and preferably 4:1 to assure good melting and melt homogeneity. The design should be approximately 35% each for feed and metering sections with the remaining 30% as the transition zone.

 

Melt temperature:160-220℃ (320-430℉)

 

Other Extrusion

Standard extruders with a length to diameter ratio of at least 20:1 are recommended. The screw should be a high compression ratio of at least 3:1 and preferably 4:1 to assure good melting and uniform melt homogeneity. The design should be approximately 35% each for the feed and metering sections with the remaining 30% as transition zone.

 

Melt temperature:180-220℃ (355-430℉)

 

Profile Extrusion

Standard extruders with a length to diameter ratio of at least 20:1 are recommended. The screw should be a high compression ratio of at least 3:1 and preferably 4:1 to assure good melting and melt homogeneity. The design should be approximately 35% each for feed and metering sections with the remaining 30% as the transition zone.

 

Melt temperature:180-220℃ (360-430℉).

 

Sheet Extrusion

Standard extruders with a length to diameter ratio of at least 20:1 are recommended. The screw should be a high compression ratio (at least 3:1 and preferably 4:1) to assure good melting and uniform melt homogeneity. The screw design should be approximately 35% each for the feed and metering sections with the remaining 30% as the transition zone.

 

Melt temperature:180-190℃ (355-375℉).

Processing

Pre Drying

Drying is not normally required. If material has come in contact with moisture through improper storage or handling or through regrind use, drying may be necessary to prevent splay and odor problems.

 

Drying time (h):3

Drying temperature (℃):80 - 100
