1. What is Rubber Density?

Definition: Rubber density is the mass per unit volume of rubber material, typically measured in kilograms per cubic meter (kg/m³).

Range: The density of rubber typically ranges from 900–1200 kg/m³ depending on the type of rubber and its composition.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of the rubber sample is divided by its volume to calculate its density.

3. Importance of Rubber Density

Details: Knowing rubber density is crucial for material selection, quality control, and engineering calculations in rubber product manufacturing.

4. Using the Calculator

Tips: Enter the mass of your rubber sample in kilograms and its volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density range for rubber?
A: Most rubber materials have densities between 900–1200 kg/m³, with natural rubber around 910-930 kg/m³.

Q2: How does rubber density affect performance?
A: Higher density rubber generally offers better mechanical properties but may be less flexible.

Q3: What factors affect rubber density?
A: Density varies with rubber type, filler content, curing process, and additives like carbon black.

Q4: How do I measure volume for irregular rubber parts?
A: Use water displacement method (Archimedes' principle) for accurate volume measurement.

Q5: Why is density important in rubber applications?
A: Density affects weight, buoyancy, vibration damping, and mechanical properties of rubber products.
