Delrin is stiffer and stronger in unfilled form, has shorter molding cycles, easy to machine, low moisture absorption, and better surface finish.
What is stronger than UHMW?
HDPE is used in a variety of applications and industries where impact resistance, high tensile strength, low moisture absorption and chemical and corrosion resistance properties are required. In terms of machining, HDPE finishes a little better than UHMW, although both materials machine well.
What’s the difference between Delrin and UHMW?
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.
What is harder than Delrin?
Chemical Resistance
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 UHMW a hard or soft plastic?
UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance.
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 HDPE?
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.
How good is Delrin?
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.
Is UHMW stronger than steel?
This means that UHMWPE fibres has an incredibly high tensile strength compared to many other thermoplastics, and this also means that the material is much stronger than steel in the fibre direction.
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.
What is similar to UHMW?
King Hy-Pact® is the smart choice for many high abuse applications requiring superior properties, outstanding flatness and a smooth surface while providing significant cost savings compared to UHMW.
What is equivalent to Delrin?
Acetal Copolymer
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).
Is Delrin scratch resistant?
It has a hard, scratch resistant surface, low friction, excellent resistance to hydrocarbons and high fatigue endurance. Machines like brass.
How strong is UHMW plastic?
UHMW Polyethylene Material Properties
| Property | Metric | English |
|---|---|---|
| Mechanical | ||
| Yield Strength | 2.14e7 – 2.76e7 | 3.1 – 4.0 |
| Tensile Strength | 3.86e7 – 4.83e7 | 5.6 – 7.01 |
| Elongation | 3.5 -5.25 | 350 – 525 |
What is the most slippery plastic?
PTFE
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. In fact, PTFE, commonly known as Teflon®, is used as the non-stick material on cookware.
Is UHMW harder than HDPE?
HDPE (high density polyethylene) is a durable, versatile, low-cost, abrasion- and chemical-resistant plastic material.UHMW (ultra high molecular weight polyethylene) is an extremely tough, abrasion-resistant, low-cost plastic, used for a wide range of wear applications.
Does Delrin break easily?
As a machined item, Delrin is particularly easy to work with. With PTFE, we need to consider the softness of the material and also its sensitivity to temperatures, with nylons and UHMWPE, we need to be careful of the part melting during machining, with PEEK, the tool itself can break, if we do not control the RPM.
Is Delrin stronger than aluminum?
Is Delrin Stronger Than Aluminum? In purely technical terms, aluminum is far stronger than Delrin, but depending on the application, Delrin parts can substitute certain aluminum parts.
Is Delrin safe to laser cut?
A 1.06 micron wavelength Fiber laser can be used to laser mark Delrin® in certain cases. The carbon based pigment in black Delrin® is heated by the laser beam, causing the surrounding polymer to foam. The foam scatters light creating an off-white, indelible mark in the Delrin® surface.
Is Delrin stronger than nylon?
Nylon and Delrin: The Bottom Line
Both nylon and Delrin are strong, durable materials that can be used for a variety of industrial, mechanical, electrical, and automotive applications. They are versatile materials that are resistant to abrasion, heat, long-term wear, and high impact.
