Acetal Copolymer The copolymer grade offers excellent performance at a slightly lower cost than Delrin®. Acetal copolymer offers consistent properties throughout the shape (being free of centerline porosity).
What material is similar to Delrin?
Delrin is a type of acetal homopolymer and therefore generally interchangeable with others of the same class. This means that Delrin still offers the same core benefits of general acetal plastics, such as: Excellent dimensional stability.
What is better than Delrin?
Acetal has a better resistance to the effects of hot water and strong caustic solutions with a high pH value when compared to Delrin®. This makes Acetal a better choice for parts and materials handling applications involving the use of strong base chemicals.
Is HDPE same as Delrin?
While HDPE Sheet and Acetal Sheet look similar, they perform quite a bit differently. Acetal is commonly known as: Delrin Homopolymer Acetal, Tecaform AH,Ensital, Unital, Pomalux, Ultraform and many more. HDPE is also known as: Ultraethylux, Densetec, Polystone G, Fortiflex, Versadur, Hostalen, and many more.
Is PTFE the same as Delrin?
Delrin is a thermoplastic material, unlike Teflon made of polytetrafluoroethylene. Whereas, Delrin is made up of polyoxymethylene. Teflon has dielectric properties which are used in electric circuits.
What is the most wear resistant plastic?
The most important polymers for friction and wear include polycarbonate and polyetherimide. Polycarbonate (PC) has good impact strength, high heat resistance, and good dimensional stability. PC also has good electrical properties and is stable in water and mineral or organic acids.
Which is harder Delrin or UHMW?
Delrin is stiffer and stronger in unfilled form, has shorter molding cycles, easy to machine, low moisture absorption, and better surface finish.
Is Acetron a Delrin?
Acetron® 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 Delrin 570?
DELRIN® 570 is a 20% glass filled homopolymer acetal with enhanced dimensional stability, high stiffness, and low creep for superior part performance and higher mechanical properties at elevated temperatures when compared to unfilled DELRIN®.
Is Delrin brittle?
Thermal Properties
Delrin does not use plasticizing for toughness: and so does not become brittle at low temperatures. Impact resistance at -40° F is only 20% less than that at room temperature.
Is Delrin PVC?

What kind of plastic is Delrin?
acetal resins
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. It has gained popularity since first being introduced to the commercial marketplace in 1960.
Is UHMW Delrin?
UHMW has surface and chemical properties that are rare to find in high-performance polymers. It is very resistant to most chemicals, UV radiation, and micro-organisms, but doesn’t have the same creep resistance as Delrin.
Is Delrin and nylon the same?
Nylon is a type of polyamide that is synthetic. The key difference between Delrin and nylon is that Delrin is a thermoplastic made from polyoxymethylene, whereas nylon is a thermoplastic made from the reaction between an amide and dicarboxylic acid.
Can Delrin be extruded?
Because Delrin is a thermoplastic, stock shapes and finished parts can also be melted and remolded or extruded several times as needed.
Is PTFE same as nylon?
Nylon vs Teflon
Nylon and Teflon (PTFE) are two of the most extensively used synthetic polymeric materials with some difference between them. Nylon is a polyamide produced by reacting an amine with a dicarboxylic acid. Teflon is produced by the polymerization of tetrafluoroethylene (F2-C = C-F2).
What plastic is scratch resistant?
Scratch-resistant polycarbonate features a proprietary coating on both sides that significantly improves the plastic sheet’s resistance to weathering, ultraviolet damage, chemicals, acids, and so much more. Properties of AR Polycarbonate: abrasion and chemical resistant. ease of fabrication and cleaning.
What is self lubricating plastic?
Self-lubricating plastics are usually placed into two categories: those that self-lubricate naturally and those that need added additives. Some resins naturally have low coefficients of friction.
What is the slipperiest plastic?
PTFE (PolyTetraFluoroEthylene) – Teflon® PTFE is inert to almost all chemicals, has outstanding electrical properties, is the slipperiest substance known and absorbs essentially no moisture. PVC (Poly Vinyl Chloride) PVC has outstanding corrosion resistance, excellent insulating properties and good mechanical strength.
Can you thread Delrin?
RE: Tapping Delrin
if it is a thru hole just use a pully tap with collant and use a feed of 10 IPM and X that by your threads per inch. We tap a lot of delrin without any problems by just using standard machining practices.
Does Delrin absorb water?
Delrin® Homopolymer
Delrin® is a family of Acetal Homopolymer whose properties include low water absorption and superior creep resistance, tensile strength, and fatigue endurance.
