Black Delrin

Extruded Acetal Copolymer is an engineering thermoplastic capable of operating in temperatures in excess of 90 degrees celsius (approximately 200 degrees Fahrenheit). Acetal is generally supplied without protective covering & as such the material is prone to surface scratching. If you are considering making an 'appearance' product like jewelry acrylic is a better alternative.
