What is the AF in Delrin?
DELRIN ® AF (PTFE-filled) is manufactured from Delrin ® homopolymer resin which has been uniformly filled with a dispersion of 20% PTFE fibers. Delrin ® AF is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important.
What is the difference between Delrin and Delrin AF?
It is a combination of PTFE fibers uniformly dispersed in Delrin® acetal resin. This combination offers better wear characteristics than unfilled Delrin®. Delrin® AF Blend retains 90% of the strength that is inherent in unmodified Delrin acetal. Some properties are changed due to the addition of the softer PTFE fiber.
What is Delrin rod used for?
Delrin rod is commonly used for gear wheels, cams, bearings, and rollers. Good electrical insulating and dielectric properties of Delrin makes it a good choice for electrically insulating components.
Is Delrin heat resistant?
Delrin® acetal homopolymer (Polyoxymethylene POM) is the ideal material in parts designed to replace metal. It combines low-friction and high-wear resistance with the high strength and stiffness such applications require. It provides a wide operating temperature range (-40 °C to 120 °C) and good colorability.
Is Delrin amorphous?
Dupont Delrin® is a premium Homopolymer Acetal or polyoxymethylene (POM-H) and it is a semi-crystalline, non-amorphous type of thermoplastic.
How hot is Delrin?
Delrin® acetal resin is a crystalline resin with a melting point of 177°C (350°F). The preferred melt temperature range is 205–225°C (400–440°F) for standard grades and 195–215°C (383–420°F) for impact modified grades (Delrin® 100ST and Delrin® 500T).
Can I melt Delrin?
The recommended melt temperature for Delrin® is 215+/-5ºC highlighted area) at which the melt for standard grades will remain perfectly stable for over 30 minutes. For best results, machine nozzles and hot runners used with Delrin® should be set to 190ºC.
Is Delrin the same thing as acetal?
Delrin is a homopolymer form of acetal . Therefore, Delrin is a derivative of acetal. All Delrin is acetal but not all acetal is Delrin. Delrin is a type of acetal produced by the company named DuPoint. The main difference between acetal and Delrin is that acetal can be found as either a homopolymer or a copolymer whereas Delrin can be found as a homopolymer. Key Areas Covered. 1. What is Acetal
What kind of plastic is Delrin?
Delrin is made from acetal homopolymer resin. It is a Polyoxymethylene plastic. Some glues on the market will be ineffective to use on Delrin as it requires heat in order to bond.
What is Delrin material?
Delrin is a trademarked name for acetal resins that are semi-crystalline thermoplastic polymers. This type of material is also known by the abbreviation POM or polyoxymethylene.
