Sustarin Acetal, in its copolymeric form, exhibits high-strength characteristics and excellent thermal properties. This conductive material has very low moisture absorption and thermal expansion, combined with surface and volume resistance.
Homopolymer Sustarin is a tough, very strong product exhibiting extremely low cold flow and thermal properties. Good dimensional stability make this material suitable for a wide range of applications.
