Below are a few images of Acetal Resin uses. Cobalt Chrome Clasp replaced with Acetal (Tooth Coloured)Clasp      Single Tooth Removable Bridge   Acetal Resin Characteristics Polyacetals belong to the category of plastics for technical purposes.They exhibit remarkable dimensional stability , hardness , rigidity , mechanical strength , good toughness and resistance to chemical agents , as well as a good anti-friction and wear performance and can so , in many cases , be used as substitutes for metals. density , 1.41 g/cm3 up to 1.43 g/cm3 structure ,highly crystaline thermoplastics with linear unbranched chains up to 75% of crystallinity. natural colour , matt white only due to their crystallinity.Can be coloured in all shades with a good surface brightness. mechanical characteristics , high mechanical strength and rigidity with good toughness , good wear resistance and a low sliding friction coefficient. chemically resistant to ( selection ) , numerous organic substances such as alcohol , aldehyde , aster , ether , glycol , petrol , mineral oil , strong alkaline solutions , and a good resistance to hydrolysis. non-resistant to ( selection ) , oxidizing chemical agents and strong acids ( pH >4 ).Long term usage in 65° C water is not possible. physiological behaviour , safe from the physiological viewpoint. cracks due to internal stress , in the open air virtually do not develop. As for greater internal stress , cracks may develop in a few substances.
