Description

Celcon® UV270Z is a nominal 27 melt flow rate acetal copolymer which has been specially stabilized to prevent discoloration and deterioration of mechanical properties from ultraviolet light exposure. Celcon® UV270Z flow is designed to fill small and difficult to process parts such as speaker grills and other interior automotive parts. The material is available in precolored black or colors.

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.

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
