Polypropylene
Polyepropylene (PP) is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene is readily modifiable to enhance flow, surface properties, stiffness and impact, as well as productivity. With its low weight, versatility, and cost benefits over traditional and other polymeric materials, polypropylene remains one of the fastest-growing polymers, widely used in many different areas such as rigid and flexible packaging, healthcare, food, hygiene, and automotive applications.
PRODUCT SOLUTIONS
A wide range of flow and mechanical properties results in the utilisation of PP Homopolymers across a broad range of plastics conversion processes, such as injection molding, blow molding as well as sheet, film and fiber extrusion.
PP Homopolymer is characterised by an excellent balance of optical and mechanical properties such as high stiffness and good impact at room temperature as well as high heat and chemical resistance.
Homopolymers
Impact copolymers are produced by the copolymerisation of ethylene with PP Homopolymer during a second reaction stage. This block type copolymerisation results in PP resins with the additional benefit of offering an excellent balance of impact strength and stiffness at both ambient and low temperatures.
Impact copolymer resins are equally at home at high and low temperatures, so they are suitable for freezer and freezer-to-microwave applications.
Impact copolymers
Random copolymers are produced via the addition of ethylene with propylene during the polymerisation process. This random incorporation of the ethylene in the homopolymer matrix during polymerisation results in PP resins with excellent transparency and gloss, with lower stiffness compared to PP homopolymers, but with higher impact properties at room temperature.
The versatility of Random copolymers allows their use during in the construction of buildings for pipes for hot and cold water distribution, cost-effectively replacing traditional alternatives.
