Plastics Abbreviations

Overview

Engineering reference data for Plastics Abbreviations in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Common Applications

These abbreviations are widely used in manufacturing, material science, and engineering specifications. Understanding them is crucial for:

• Material Selection: Choosing the correct plastic for an application based on its chemical properties.
• Reading Technical Drawings & Data Sheets: Interpreting component specifications and material certifications.
• Quality Control & Compliance: Ensuring materials meet required industry standards and regulations.

When selecting a plastic, properties such as temperature resistance, chemical compatibility, tensile strength, and cost are directly determined by its polymer type, which is indicated by its abbreviation.
