Delrin behaves like most engineering materials in that as temperature increases, elongation increases and strength decreases. Delrin has a tensile strength at room temperature of 10,000 psi, no true yield point and a stiff flexural modulus of 410,000 psi.
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. The higher molecular weight resin formulations will deliver even greater toughness.
The Delrin-steel coefficient of friction is very low (0.1-0.3), and friction values remain virtually unchanged over a wide range of temperatures, loads and relative surface speeds.
Good strength retention at elevated temperatures: at 200° F, tensile strength is 2,000 psi and flexural modulus is 180,000.
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.
Delrin's upper service temperatures are: 180° F in air, 150° F in water, with brief peaks to 250° F.
Delrin has great resistance to organic solvents, in fact, there are virtually no common solvents for Delrin at temperatures under 160° F. However, environments involving strong acids, bases or oxidizing agents are not suitable for this material.
Excellent staining and discoloration resistance at temperatures under 160° F.
Delrin is perfect for underground applications, as it is not attacked by insects, rodents or fungi.
An excellent dielectric, Delrin has remarkably low dissipation factors and dielectric constants over a wide range of frequencies and temperatures.
Delrin retains good electrical properties in high humidity and even during complete immersion in water.
