Celcon? LM90Z
Acetal (POM) Copolymer
Celanese Corporation
产品说明：
Celcon? LM90Z is a UV stable, nominal 9 melt flow acetal copolymer which is capable of being permanently marked by a laser. It gives protection against property and color deterioration in applications where significant UV exposure is anticipated from sunlight or artificial lighting. Parts molded from Celcon? LM90Z can be lasermarked with barcodes, identification numbers, designs, 2-D symbology, etc.
