More Durable, Longer Life
Delrin® acetal homopolymer provides a superior combination of mechanical properties such as tensile strength, stiffness, creep and fatigue resistance which provide better dimensional stability under higher temperatures than existing copolymers.
The excellent creep resistance and high tensile yield strength of Delrin® allow you to design window lifterplates and sliders that retain their shape over time at ambient and elevated temperatures. Delrin® homopolymer shows significantly lower creep strain at elevated temperatures than a typical copolymer.
Better creep resistance, lower overall cost
Delrin® demonstrates superior performance which allows for the reduction of potential warranty costs, decreased assembly time and the elimination of secondary operation, which could result in savings up to 25%.
DuPont offers expert application development assistance ready to help you in every phase of your project. Our technical capabilities enable us to help with recommending the right Delrin® grade, assisting with part and tooling design input and review, and molding process start up and optimization.
Choosing the right material
Delrin® acetal homopolymer and acetal copolymer offer outstanding performance in creep resistance, flexural fatigue and impact strength. These properties are essential for durability and longevity in this type of application.
Improve Performance at various temperatures
Delrin® allows for improved performance across an operating temperature range of -40C to 90C, providing low temperature impact and low creep at high temperature.
The load carrying capability of Delrin® also allows for smaller and thinner wall part to support similar loads.
We have the right materials, technology, and technical resources to help you design and manufacture superior lifterplates and other parts and system components. Please contact the nearest DuPont representative for your country.
