What is the difference between copolymer and homopolymer acetal?
Copolymer and homopolymer acetals have slightly different molecular structures resulting in slightly different physical properties. For example, homopolymer acetal has slightly higher strength properties but exhibits centerline porosity.
Is Delrin® autoclaveable?
Delrin® acetal resin survived 100 15-minute cycles of 121 degrees C (250° F) in an autoclave. However, additional cycles could result in surface chalking and hydrolysis.
What is the difference between Delrin® 100 AF and HPV-13®
Delrin® 100 AF Blend contains 13% PTFE fibers. HPV-13® contains 13% PTFE powder. Both are brown in color and are considered to be bearing grades of homopolymer acetal.
What is the difference between Delrin® 100 and 150?
Delrin® 100 and 500 are injection molding grades but can be extruded in smaller diameter rod (up to around 2″ diameter) and thinner plate (up to about 2″ thick). Delrin® 150 and 550 are the extrusion grades of Delrin® 100 and 500, respectively.
Can you please tellfter the me what grade/type of acetal for the ASTM designation POM211 refers, also does B42350 after the POM211 mean anything to you?
ASTM designation POM211 refers to Acetal copolymer. The B45350 after the POM211 refers to physical properties listed in table B in ASTM D 4181 and ASTM D 6100 for acetal copolymer.
