Ciwenkai 6PCS Acetal Copolymer Round Rod,Acetal Rod Opaque Black,0.25 Inch Diameter and 12 Inch Length, StandardTolerance.Main features: resistance to organicsolvents, insoluble at room temperature, good low temperature performance,thermal deformation temperature similar to PC/PTFE and nylon, higher than PVCPS/PE. High compressive strength, second only to glass fiber, excellent wearresistance and creep resistance. High rigidity mechanical strength andhardness, high size and shape stability. It still maintains toughness at -40°C, has good sliding properties, does not absorb water, has good wearresistance, chemical resistance and hydrolysis resistance, and has goodmachinability.Polyoxymethylene POM is a general-purposethermoplastic engineering plastic with excellent mechanical properties,electrical properties, wear resistance, dimensional stability, chemicalcorrosion resistance, especially outstanding fatigue resistance, and goodself- lubricating properties. It is an alternative to metal. , especially idealengineering plastics for non-ferrous metals and alloy products such as copper,aluminum and zinc. According to the excellent conductivity of polyoxymethylenePOM, the products that can be developed are widely used in dry textilemachinery, plastics, food, electronics, electrical, automobile, light industry,chemical industry, construction and other fields.Application areas: suitable for makingsliding parts, precision mechanical parts and water- resistant parts, such as:bearings, gears, impellers, cams, bushings. Washers, guide rails, receivinghandles, handles, etc., materials for fixtures.Disadvantages: Not resistant to acid,especially not resistant to mineral acid, not resistant to ultraviolet rays,not self-extinguishing, not close to fire, not resistant to impact.SpecificationsSize:Rod Diameter: 0.25inch/5mmRod Length: 12inch/305mm
