What You'll Learn
Delrin is a type of acetal homopolymer
Delrin's high strength and stiffness give it an impressive compressive strength of 5200 psi, which is comparable to that of concrete. This, combined with its superior dimensional stability, makes it capable of maintaining its original shape and dimensions under varying temperature and humidity conditions. This property is especially advantageous in applications sensitive to dimensional changes, such as gears and bearings.
Another key characteristic of Delrin is its low moisture absorption. This feature, along with its chemical resistance to hydrocarbons, solvents, and neutral chemicals, allows it to maintain its physical and mechanical properties even in moist or wet environments. Consequently, Delrin is well-suited for pump and valve components, water management controls, and kitchen appliances.
Delrin also exhibits high fatigue and creep resistance, making it resistant to cracks and material deformation over time. Additionally, Delrin is highly resistant to organic solvents, with no common solvents at temperatures under 160° F. However, it is important to note that Delrin is not suitable for environments with strong acids, bases, or oxidizing agents.
Delrin's versatility extends to its use in medically-related fields. It is suitable for valves, pumps, inhalers, syringes, prosthetics, implants, and various consumer goods requiring strength and durability, such as sports equipment and food containers. Furthermore, Delrin's high impact resistance at low temperatures makes it suitable for aerospace applications, including safety restraint components and door systems.
