产品说明

AH10P is an acetal homopolymer material, with a high viscosity suitable for injection molding applications where superior toughness or dynamic fatigue performance is required, or for best fill of heavy wall section components with least "sink". AH10P also offers a melt viscosity suitable for extrusion of stock shapes such as rod and slab, or simple profiles. Acetal Homopolymer is a highly crystalline engineering thermoplastic polymer exhibiting predictable mechanical properties over a wide temperature range and for long time periods. A combination of high tensile strength and rigidity, resilience and toughness, outstanding dynamic and static fatigue resistance, excellent dimensional stability, resistance to the effects of a very wide range of chemicals, oils and solvents and natural lubricity makes acetal homopolymer the material of choice for a wide range of applications in all major end-use categories.
