PET
Polyethylene Terephthalate
PET is one of the most widely recycled plastics globally. It's the standard material for water bottles and food packaging due to its excellent barrier properties and clarity.
Common Uses
- Water and beverage bottles
- Food containers
- Polyester fiber
- Strapping
Properties
- Transparent and glossy
- High barrier to gas and moisture
- Lightweight
- Recyclable
Processing Machines
- Injection Molding (preforms)
- Blow Molding (bottles)
HDPE
High-Density Polyethylene
HDPE is highly versatile and widely used in Ethiopia's plastic industry. Ideal for jerry cans, buckets, and containers due to its rigidity and chemical resistance.
Common Uses
- Milk jugs and bottles
- Jerry cans
- Pipe systems
- Buckets and containers
Properties
- High strength-to-density ratio
- Resistant to chemicals
- Rigid and durable
- Food-safe
Processing Machines
- Injection Molding
- Blow Molding
PVC
Polyvinyl Chloride
PVC is the third most produced synthetic plastic. Widely used in construction for pipes and fittings. Rigid PVC is used for profiles; flexible PVC for wires and medical tubing.
Common Uses
- Pipe and pipe fittings
- Window and door profiles
- Wire insulation
- Medical devices
Properties
- Durable and long-lasting
- Flame resistant
- Excellent electrical insulation
- Low cost
Processing Machines
- Injection Molding
- Extrusion
LDPE
Low-Density Polyethylene
LDPE is the material behind most plastic bags and flexible packaging. Its flexibility and low cost make it essential for packaging applications.
Common Uses
- Plastic bags
- Squeeze bottles
- Flexible films
- Packaging materials
Properties
- Flexible and tough
- Good moisture barrier
- Transparent or translucent
- Food-safe
Processing Machines
- Blow Molding
- Film Extrusion
PP
Polypropylene
PP is the workhorse of the injection molding industry. Chairs, automotive components, and food containers are made from PP. It's one of the most produced plastics globally.
Common Uses
- Chairs and furniture
- Food containers
- Automotive parts
- Medical syringes
Properties
- High heat resistance
- Excellent chemical resistance
- Lightweight
- Fatigue resistant
Processing Machines
- Injection Molding
- Blow Molding
PS
Polystyrene
PS comes in rigid form (used for disposable containers and electronics housings) and expanded foam form (EPS, used for insulation and packaging). Common in food service.
Common Uses
- Disposable cups
- Food service containers
- Electronics housings
- Insulation foam
Properties
- Rigid and brittle
- Clear and glossy
- Low thermal conductivity (foam)
- Low cost
Processing Machines
- Injection Molding
Other
Other Plastics (ABS, PC, Nylon, etc.)
Category 7 covers engineering plastics like ABS (tough, impact-resistant), Polycarbonate (transparent, high-strength), and Nylon (high temperature, wear-resistant). Used for demanding applications.
Common Uses
- Engineering components
- Automotive parts
- Electronic devices
- Medical equipment
Properties
- High performance
- Specialized properties
- Often engineering-grade
- Application-specific
Processing Machines
- Injection Molding (with special configuration)
