1. Introduction to Plastic Technology
Definition and Scope
- Plastic Technology involves the study of polymers, their synthesis, processing, design, and applications.
- It intersects with chemistry, engineering, environmental science, and material science.
- Key sectors: packaging, automotive, healthcare, construction, and consumer goods.
Historical Evolution
- 1862: Alexander Parkes invents the first synthetic plastic (Parkesine).
- 1907: Bakelite, the first fully synthetic plastic, is created by Leo Baekeland.
- Post-WWII: Mass production of plastics revolutionizes industries.
Importance in Modern Society
- Lightweight, durable, and cost-effective materials.
- Critical for medical devices (e.g., syringes), renewable energy (wind turbine blades), and electronics.
- Global plastic production: 400 million metric tons annually (2023).
2. Core Concepts in Plastic Technology
Types of Plastics
- Thermoplastics (e.g., polyethylene, PVC): Re-moldable, used in bottles, pipes.
- Thermosets (e.g., epoxy, silicone): Heat-resistant, used in adhesives, insulators.
- Bioplastics: Derived from renewable sources (e.g., corn starch).
Manufacturing Processes
- Injection Molding: Molten plastic injected into molds (e.g., toys, automotive parts).
- Extrusion: Continuous shaping of plastics (e.g., pipes, sheets).
- Blow Molding: Used for hollow objects (e.g., bottles).
- 3D Printing: Additive manufacturing for prototypes and custom parts.
Properties and Testing
- Mechanical (tensile strength), thermal (melting point), and chemical resistance.
- Testing methods: FTIR spectroscopy, DSC (Differential Scanning Calorimetry).
Applications
- Automotive: Lightweight components for fuel efficiency.
- Healthcare: Biocompatible implants and disposable tools.
- Packaging: Flexible and barrier films to extend food shelf life.
