Frequently Asked Questions

Common questions about teflon (ptfe) weight.

Virgin PTFE has a density of 2.2 g/cm³ (0.079 lb/in³). Filled PTFE compounds can range from 2.1 to 2.3 g/cm³ depending on additives like glass fiber or carbon. Always check with your supplier for exact density values.

Weight affects structural load calculations, shipping costs, and material procurement budgets. PTFE's low density (about 1/4 the weight of steel) makes it ideal for applications where weight reduction matters without sacrificing chemical resistance.

The calculator uses standard density values and provides estimates within 2-5% of actual weight. Manufacturing tolerances, material grade, and moisture content can affect real-world weights slightly.

Yes, if you know the specific density of your filled compound (glass-filled, carbon-filled, etc.), enter that value instead of the standard 2.2 g/cm³. Filled grades typically range from 2.1 to 2.3 g/cm³.

The calculator works for sheets, rods (solid cylinders), tubes (hollow cylinders), and custom shapes where you can calculate volume. For complex geometries, break them into simpler shapes and calculate each separately.

How to Calculate

To calculate PTFE weight, first determine your part's volume based on its shape: for sheets, multiply length × width × thickness; for rods, use πr²h; for tubes, use π(R² - r²)h where R is outer radius and r is inner radius. Then multiply the volume by PTFE's density (typically 2.2 g/cm³ or 0.079 lb/in³). Convert units as needed to get weight in your preferred unit (pounds, kilograms, etc.).

Formula & Method

**Weight = Volume × Density**

**Sheet:** Volume = Length × Width × Thickness

**Rod:** Volume = π × r² × Length (where r = radius)

**Tube:** Volume = π × (R² - r²) × Length (where R = outer radius, r = inner radius)

**Standard PTFE Density:** 2.2 g/cm³ (0.079 lb/in³)
