WHAT IS IT?
Polypropylene (PP) is a thermoplastic polymer produced from propylene monomer (C₃H₆). It is the second most produced plastic globally after polyethylene, and one of the most versatile materials in existence. Its combination of stiffness, chemical resistance, and processability makes it suitable for an enormous range of applications.
TYPES
Homopolymer PP (PPH): Highest stiffness and clarity. Used in rigid packaging, fibres, caps.
Random Copolymer PP (PPRC): More flexible and transparent than homopolymer. Pipes, food containers, medical packaging.
Impact Copolymer PP (PPIC): Added rubber for impact resistance. Automotive bumpers, appliance casings.
GRADES BY APPLICATION
Injection Moulding: Chairs, containers, automotive interiors
Film Grade: BOPP (Biaxially Oriented PP) for flexible packaging, snack bags, labels
Fibre Grade (Raffia): Woven sacks, ropes, carpets — huge demand in Southeast Asia and Africa for agricultural bagging
Pipe Grade (PPR): Hot and cold water pipes
KEY USES
Flexible and rigid packaging (largest use)
Woven bags and sacks (FIBC, raffia)
Automotive parts
Appliances
Medical devices and syringes
Textiles (geotextiles, nonwovens)
Pipes and fittings
TRADE CORRIDORS
Major producers: China, Middle East (Saudi Arabia, UAE), South Korea, India
Major buyers: Southeast Asia, Africa, India, Europe
Tetra relevance: China and South Korea → SEA/East Africa corridor. Raffia and injection grades high demand in East Africa.
