2. Detailed comparison of different types of plastics
PVC (Polyvinyl Chloride) plastic
- AdvantageGood insulation, corrosion resistance, fire retardant, and inexpensive.
- ApplicationWater pipes, partitions, plastic flooring, signage, building materials.
- DisadvantagesMay contain harmful additives if production is not properly controlled.
PET plastic (Polyethylene Terephthalate)
- AdvantageTransparent, lightweight, excellent airtightness, and food-safe.
- ApplicationPlastic water bottles, food packaging, shrink wrap, polyester fabric.
- DisadvantagesEasily deformed under high temperatures.
ABS plastic (Acrylonitrile Butadiene Styrene)
- AdvantageHard, impact resistant, and easy to machine.
- Application: Electronic devices (laptop cases, remotes), toys, car parts.
- DisadvantagesNot resistant to sunlight, easily ages outdoors.
HDPE plastic (High-Density Polyethylene)
- AdvantageDurable, lightweight, waterproof, and chemical-resistant.
- ApplicationPlastic containers, trash cans, shopping bags, water pipes.
- DisadvantagesNot transparent, difficult to print directly on.
PP (Polypropylene) plastic
- Advantage: Moderately stiff, flexible, and heat-resistant (up to 120°C).
