What Delrin 150?
Delrin® 150 is a high viscosity acetal homopolymer for extrusion processes. It has excellent thermal stability, low die deposit, and enhanced crystallization for low porosity. The material offers very high stiffness, low warpage, and low creep for superior part performance under stress.
What is Delrin material used for?
For automotive, mechanical, and industrial purposes, Delrin® can be used to make bearings, bushings, gears, fittings, sliding and guiding parts, rollers, conveyor systems, scraper blades, and various electrical insulator parts.
Is Delrin hard or soft?
Properties & Grades of Machined Delrin
This strong, stiff and hard acetal homopolymer is easy to machine and exhibits dimensional stability and good creep resistance, among several other desirable qualities.

What color is Delrin 150?
Delrin® Acetal Sheet Homopolymer Color, Delrin®150, Yellow, (0.031 in x 24 in x 48 in) | Curbell Plastics.
Is Delrin 150 FDA approved?
Not only is Delrin certified for use by the FDA, it is also certified by the NSF and USDA, enabling it to be used in dairy applications as well.
Is Delrin a strong material?
Delrin® plastic properties and mechanical specifications
Delrin® plastic is strong, rigid, and resistant to impact, creep, abrasion, friction, and fatigue. It’s also well known for its excellent dimensional stability during high-precision machining.
Where is Delrin used?
Leading companies across the globe specify Delrin® acetal homopolymer from DuPont for high-load mechanical applications such as gears, safety restraints, door systems, conveyor belts, healthcare delivery devices, and other demanding products and parts.
How long does Delrin last?
Delrin has outstanding fatigue resistance, almost indefinitely withstanding cyclic compressive/tensile stressing 5,000 psi. Delrin does not permanently deform or retain dents, and has good impact toughness.
What is stronger than Delrin?
Despite these similarities, nylon is generally stronger than Delrin. Extruded nylon has a tensile strength of 12,400 PSI and cast nylon has a tensile strength of between 10,000 and 13,500 PSI.
What is better 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.
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 the difference between Delrin and nylon?
The major difference between Delrin and nylon comes from their method of creation. Delrin is a thermoplastic created from polyoxymethylene, while nylon is a synthetic thermoplastic from a reaction between a dicarboxylic acid and an amide. Both of these materials have desirable physical and mechanical properties.
Is Delrin a polymer?
Delrin®, the stiffest unreinforced engineering polymer available, is the preferred choice by designers, extruders, molders and brand owner, as it allows potential cost and environmental savings.
Is Delrin chemical resistant?
Delrin has excellent chemical resistance to most organic solvents. This polymer’s high tensile strength also permits superior threads that are very resistant to wear. Delrin is not suitable for use with acids, bases, or oxidizing agents. PCTFE has excellent chemical resistivity.
Is Delrin brittle?
Is Delrin Brittle? Because Delrin doesn’t use plasticizing for its toughness, it doesn’t become brittle at low temperatures.
What is another name for Delrin?
Acetal
Acetal is the common name for a family of thermoplastics with the chemical name “PolyOxyMethylene”, or POM. Acetal is available in two general types of resins: Copolymer acetal (POM-C), and homopolymer acetal (POM-H); commonly called Delrin®.
Does Delrin melt?
Melt Temperatures
Delrin® acetal resin is a crystalline resin with a melting point of 177°C (350°F).
