1. What is Polypropylene (PP) Density?

Definition: This calculator converts the density of polypropylene from kg/m³ to g/cm³.

Purpose: It helps material scientists, engineers, and manufacturers work with density values in different units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho_{g/cm³} \) — Density in grams per cubic centimeter
• \( \rho_{kg/m³} \) — Density in kilograms per cubic meter

Explanation: Since 1 g/cm³ equals 1000 kg/m³, we divide the kg/m³ value by 1000 to get the equivalent in g/cm³.

3. Importance of PP Density

Details: Polypropylene typically has a density between 0.90–0.91 g/cm³ (900-910 kg/m³). Knowing the exact density is crucial for material selection, product design, and manufacturing processes.

4. Using the Calculator

Tips: Enter the density in kg/m³ (default 900 kg/m³ for PP). The calculator will instantly convert it to g/cm³.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density range for polypropylene?
A: PP typically ranges from 0.90–0.91 g/cm³ (900-910 kg/m³), depending on the specific formulation and additives.

Q2: Why convert between these units?
A: Different industries and applications use different units, and conversions are often needed for material specifications and calculations.

Q3: How does PP density compare to other plastics?
A: PP is relatively lightweight compared to many other plastics. For example, PVC has a density of about 1.3-1.45 g/cm³.

Q4: Does temperature affect PP density?
A: Yes, like all materials, PP's density changes slightly with temperature due to thermal expansion/contraction.

Q5: Where can I find density specifications for my PP material?
A: Check the material datasheet from your supplier, as different additives and fillers can modify the base density.
