Description
Celcon® acetal copolymer grade M15HP is a creep resistant, high viscosity polymerproviding optimum performance in general purpose injection molding. This grade provides overall excellent performance in applications requiring high stiffness.
 
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 with a 2:1 compression ratio) can result in unmelted particles and poor thermal homogeneity. Using a high back pressure to make up for a low compression ratio may lead to excessive shear heating and deterioration of the Celcon material.
 
Melt temperature: Preferred range 205-220℃ (400-430℉) Melt temperature should never exceed 230℃ (450℉).Mold surface temperature: preferred range 93-121℃ (200-250℉) especially with wall thickness less than 1.5 mm (0.060 in.). Wall thickness greater than 3 mm (1/8 in.) may use a cooler (82℃/180℉) mold surface temperature and wall thickness over 6 mm (1/4 in.) may use a cold mold surface temperature as low as 25℃ (80℉). In general, mold surface temperatures lower than 82℃ (180℉) may produce a hazy surface or a surface with flow lines, pits and other included defects.
 
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℉)
 
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℉).

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
