Delrin was created by Dupont, and is a favorite brand name and the most frequently used Homopolymer Acetal. To take one example,, Delrin is well suited for tiny dimensions, thin-walled bushings offering unsurpassed toughness along with rigidity, typical of homopolymer acetal. Compositions Delrin can be found in four viscosities, to be able to meet with the flow requirements of a large array of end-use applications.
Natural grade is FDA, NSF and USDA compliant.
Delrin® is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics. Delrin® sheets and rods possess high tensile strength, creep resistance and toughness.
Every type of acetal has its own set of benefits and drawbacks, and yet they are alike in many facets. It is a proven gear material, Sheridan said. These two sorts of acetal has its own set of benefits and drawbacks, and yet they are alike in many facets. TECAFORM Acetal is a trade name for Ensinger Plastics for their Acetal materials including Delrin, and is appropriate for a wide selection of applications.
Acetal and Delrin (POM-C/POM-H)
Polyoxymethylene (POM), also known as acetal, Polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. As with many other synthetic polymers, it is produced by different chemical firms with slightly different formulas and sold variously by such names as Delrin, Celcon, Ramtal, Duracon, Kepital and Hostaform.
As the interior material cools, there’s an equivalent decrease in volume. As the interior material cools, there’s a corresponding decrease in volume. Most saddle materials, like brass or aluminum, are available at the local hardware shop.
Things You Should Know About Dupont Delrin Rod
If you are not certain of which plastic will fit your program, give us a call! Professional Plastics may expect you to offer certain information or data as a way to submit a review. Vinyl plastics are normally clear, higher impact, exceptional clarity and processing performance.
POM is supplied in a granulated form and can be formed into the desired shape by applying heat and pressure. The two most common forming methods employed are injection molding and extrusion. Rotational molding and blow molding are also possible. Typical applications for injection-molded POM include high performance engineering components (e.g. gear wheels, ski bindings, yoyos, fasteners, lock systems) and the material is widely used in the automotive and consumer electronics industry. There are special grades that offer higher mechanical toughness, stiffness or low friction/ wear properties.
Filled Acetal or Delrin Products
Ensinger produces a filled Acetal called Tecaform™ HPV 13 is a brown homopolymer acetal with an internal PTFE lubricant. Its low coefficient of
friction, excellent PV values, toughness, wear resistance, and machinability make it an exceptional material for use in many industrial and military components with moving parts. Additionally, Tecaform™ HPV 13 has superior chemical resistance and flexural fatigue properties, as well as low moisture absorption associated with acetal materials. The Delrin AF Blend is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. It is a combination of PTFE fibers uniformly dispersed in Delrin acetal resin. This combination offers better wear characteristics than unfilled Delrin. The natural color of Delrin AF Blend is dark brown.
