Is Delrin low friction?
Delrin® is well-known for its industry-leading mechanical properties, of which low wear and low friction are key. These features can also be enhanced with additional additives such as PTFE, siloxane and specialised lubrication oils.
What is Delrin AF Blend?
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®.
Can Delrin be used as a bearing?
Delrin is a lightweight, low-friction, and wear-resistant thermoplastic which makes it a good bearing material. It can also handle moderate high temperatures up to 90°C which makes Delrin ideal for medium speed-light load bearing applications.
Is acetal low friction?
Acetal (polyoxymethylene or POM) is a high strength, low friction engineering plastic that has excellent wear properties in both wet and dry environments. Acetal is chemically resistant to hydrocarbons, solvents, and neutral chemicals.
Is Delrin anti static?
It is available in ESD-Safe delrin plastic. The tip prevents static and mechanical damage. It requires a continuous vacuum source.
What Delrin 100?
Delrin® 100P is a high viscosity acetal homopolymer for use in easy-to-fill molds. Delrin® 100P provides a great combination of toughness and strength, improved processing thermal stability and productivity for injection molding, and low VOC emissions.
Is Delrin a PTFE?
Delrin AF is a combination of 10-25% oriented PTFE fluorocarbon fibers uniformly dispersed in Acetal/Delrin resin. The resulting product is one that possesses the strength, toughness, and dimensional stability of Acetal with the added properties of PTFE, which is one of the world’s most slippery solid materials.
Is Delrin material ESD Safe?
Maximum Operating Temperature: +212°F. Inner Diameter: 0.02in. Outer Diameter: 0.03″ ESD Safe (Yes/No): Yes.
Does Delrin creep?
Delrin plastic works as an excellent replacement for metal because of its high-tensile strength, low-friction and high-wear resistance, creep and warp resistance, and overall durability and toughness.
What is the coefficient of friction for rubber?
Typical values for the coefficient of friction when sliding is occurring, i.e. the dynamic coefficient of friction are: for polished oiled metal surfaces, less than 0.1. for glass on glass, 0.4. for rubber on tarmac, close to 1.0.
Why does rubber have high friction?
Current theories suggest that when rubber moves over smooth surfaces, it’s the molecular forces between the two that are the main cause of friction. But when the surface is rough, it’s the deformation of entire molecular layers of rubber that’s the chief cause of friction.
What is the coefficient of friction of silicone rubber?
approximately 1.0
Silicone is naturally quite tacky, with a coefficient of friction of approximately 1.0 in many cases. On many of our products, processes are applied to reduce the coefficient of friction.
What is the color of Delrin AF blend?
– The natural color of Delrin AF Blend is dark brown. 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.
What are Delrin® AF bearings made of?
They are a combination of PTFE fibers (or PTFE powder) uniformly dispersed in Delrin® acetal resin. This combination offers better wear characteristics than unfilled Delrin® due to the presence of PTFE acting as a solid lubricant. Bearings made of Delrin® AF can operate at higher speeds while extending life to the component.
Is Delrin a homopolymer?
Delrin® AF, Delrin® 100AF and Delrin® AF Blend belong to a family of PTFE filled DuPont acetal homopolymers. DuPont Delrin® is a popular acetal homopolymer brand name and the most commonly used acetal homopolymer.
Is there another low cost injection moldable plastic for Delrin?
If delrin is not suitalbe, is there another common, low cost injection moldable plastic that would be suitable? Check DuPont. I recommend you go to LNP Plastics (now part of GE Plastics) and check out their design guide for Lubricomp. Therein are tables for Plastic-on-Plastic comparisons.
