Plastic Materials

Plastics are synthetic or semi-synthetic polymers that have revolutionized modern manufacturing due to their versatility, durability, and cost-effectiveness. These materials consist of long-chain polymer molecules that can be molded, extruded, or cast into various shapes when softened by heat, then hardened into final products.
The key characteristics of plastics are lightweight, corrosion-resistant, design flexibility, electrical insulation, varied transparency, cost-effective production. Major plastic categories are thermoplastics(re-meltable), thermosets(permanent-set), engineering plastics.
