Delrin Weight Calculator

Historical Background

Delrin, also known as polyoxymethylene (POM), is a type of thermoplastic that has high strength, stiffness, and good wear resistance. Invented by DuPont in the 1960s, Delrin is widely used in various industries, including automotive and aerospace.

Formula

The formula to calculate Delrin weight is:

\[ W_d = L \cdot W \cdot T \cdot d \]

where:

• \(W_d\) is the Delrin weight in pounds,
• \(L\) is the length in inches,
• \(W\) is the width in inches,
• \(T\) is the thickness in inches,
• \(d\) is the density, which for Delrin is \(0.05222 \, \text{lbs/in}^3\).

Example Calculation

Let's say the Delrin sheet measures 10 inches in length, 5 inches in width, and 1 inch in thickness. Its weight can be calculated as:

\[ W_d = 10 \cdot 5 \cdot 1 \cdot 0.05222 \approx 2.611 \, \text{lbs} \]

Importance and Usage Scenarios

Calculating the weight of Delrin is crucial in determining the suitability of the material for specific applications, especially where weight plays a significant role in design, such as in the automotive and aerospace industries.
