Testo del prodotto

Common features of Delrin® acetal resins include mechanical and physical properties such as high mechanical strength and rigidity, excellent fatigue and impact resistance, as well as resistance to moisture, gasoline, lubricants, solvents, and many other neutral chemicals. Delrin® acetal resins also have excellent dimensional stability and good electrical insulating characteristics. They are naturally resilient, self-lubricating, and available in a variety of colors and speciality grades.

Delrin® acetal resin typically is used in demanding applications in the automotive, domestic appliances, sports, industrial engineering, electronics, and consumer goods industries.

Delrin® 577 is a medium viscosity acetal homopolymer containing 20% glass fiber filler for injection molding.  It has very high stiffness, low warpage, and good creep resistance for superior performance at elevated temperature.  It contains carbon black for improved weathering.

Stampaggio ad Iniezione

Drying is recommended, but not necessary for newly opened packaging stored in a dry location.

Follow the drying guidelines above in the following cases:

·         If moisture is above the Processing Moisture Content recommendation,

·         When a resin container is damaged,

·         When the material is not properly stored in a dry place at room temperature, or

·         When packaging stays open for a significant time.
