1. What is Density of LLDPE?

Definition: Linear Low-Density Polyethylene (LLDPE) density typically ranges between 918-935 kg/m³.

Purpose: This calculator helps determine the density of LLDPE material based on its mass and volume.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

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

Explanation: Density is calculated by dividing the mass of the material by its volume.

3. Importance of Density Calculation

Details: Knowing the density of LLDPE is crucial for material selection, quality control, and manufacturing processes.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density range for LLDPE?
A: LLDPE typically has a density between 918-935 kg/m³, which is slightly higher than LDPE but lower than HDPE.

Q2: How does LLDPE density compare to other polyethylenes?
A: LDPE: 917-940 kg/m³, LLDPE: 918-935 kg/m³, HDPE: 941-965 kg/m³.

Q3: What factors affect LLDPE density?
A: Comonomer type, branching, crystallinity, and processing conditions can all affect density.

Q4: Why is density important for LLDPE?
A: Density affects mechanical properties, processability, and end-use performance of the material.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but actual material density may vary based on measurement accuracy and material consistency.
