Polyacetal (Delrin) polymers, properly called Polyoxmethylene (POM), are highly crystalline linear thermoplastic, provides predictable mechanical, chemical and electrical properties, over a broad temperature range for long time periods. Polyacetal are hard, strong and stiff, have good toughness, low co-efficient of friction against self and other materials. Polyacetal are non-hygroscopic, maintain good dimensional stability and have excellent machinability, which enhance its application in industrial fields. Some of the wide used components made in Polyacetal for industrial applications are Valves, Impellers, Gears, Cams, Chain Links, Spray Nozzles, Seatings, Guides etc. Availability: Polyacetal materials are available in the forms of Stock-shapes like Round, Rectangular, Square Bars, Tubes, Blocks, Sheets, Chains and in Finished Molded & Machined Components as per Cliental specifications.   Applications: Bushing Bearings Camshaft Chains Fasteners Wheels Spiders Guides SILIENT FEATURES : Excellent Dimensional Stability Crystalline linear Molecular Structure Very Tough & Strong Good Dielectric Strength Excellent Machinability Hard & Smooth Surface Exceptional Dynamic Fatigue Strength PHYSICAL PROPERTIES : PROPERTIES METHOD UNIT VALUE Tensile Strength DIN 53455 N/mm2 68 Elongation at Break DIN 53455 % 20-30 Co-efficient of Linear Expansion Teitz dilatometer oC 1.3 X 10-4 Compressive Strength ASTM D 695 Kgf/cm2 320 Impact Strength (notch) DIN 53453 Kg/cm2 9 Specific Gravity DIN 53479 gm/cc 1.41 Hardness ASTM D 2240 Shore D 80-85 Service Temperature (Max)   oC 90 - 130 Co-efficient of Friction     0.15 - 0.50 CONTACT Yogesh Maheshwari Plastic Shilp Udyog 5-1-244/1, Old Ghasmandi, Secunderabad 500003, AP, INDIA.
