Polypropylene (PP)
Polypropylene (PP) is the second most widely used thermoplastic in the world after polyethylene and is produced by polymerization of propylene with chemical formula (C3H6)n. While the properties of polypropylene are similar to those of polyethylene, there are specific differences, they include a lower density and a higher melting point (polypropylene does not melt at temperatures below 160°C), combined with higher stiffness, strength and resistance to bases, acids and chemical agents. There are three main groups of polypropylene, which are determined by the composition of the polymer chain and changing their specific properties.
We can offer you the complete range of polypropylenes including:
- PPH, Phthalate free polypropylene homopolymers – Polypropylene homopolymer is a thermoplastic polymer obtained by polymerization of propylene with catalysts. Homopolymers can be used by various processing technologies, such as injection molding, blow moulding, extrusion and thermoforming, and are widely used in the production of packaging, household goods, textiles, films, healthcare, pipes, as well as various automotive and electrical parts.
- PPC, Phthalate free polypropylene impact copolymers – Polypropylene copolymers are a thermoplastic polymers obtained by copolymerization with ethylene, but in this type of material, the ethylene content is much higher than in conventional copolymers. This results in a much stronger material with excellent impact strength even at low temperatures.
- PPR, Phthalate free polypropylene random copolymers – Polypropylene random copolymers are thermoplastic polymers obtained by polymerization of propylene, with ethylene or butene bonds introduced into the polymer chain. These resins provide a wide range of characteristics and allows its processing by injection molding, blasting, thermoforming and extrusion in products requiring transparency, good gloss and good aesthetic properties.
- Polypropylene Compounds – Available as homopolymer and copolymer in different grades, such as mineral filled, glass fires reinforced, colored to RAL or Pantone, impact modified and flame retardant UL94 V2 and V0 (also halogen free grades) with UL certification (yellow card)
Specialty products
- Automotive – Polypropylene homopolymers, impact copolymers and PP compounds providing very high-impact resistance, scratch resistance, excellent aesthetical properties and low volatile organic compound (VOC) emissions, suitable for:
- Interior applications such as instrument panels, door panels, central consoles and pillars
- Under the bonnet parts subjected to high thermal stress (light housings, HVAC elements), AC inserts, heaters and air conditioning units
- Exterior applications like bumpers, doors and steering columns
- Packaging – Our portfolio of special polypropylene for packaging is able to meet the most demanding of customers' requirements for rigid and flexible packaging. We are able to offer grades with enhanced melt flow rate (MFR), lower sealing temperatures, improved organoleptic and optical properties. These properties are allowing the production of containers with glossier or more matte appearance, key features helping our clients to improve their efficiency and performance and that safeguard the organoleptic properties of food without changing its colour, smell or taste
- Polypropylene for fibers, nets and yarns – Our special grades of polypropylene nonwoven and spunbond have excelent mechanical properties and are suitable for extrusion of nets, raffia, high tenacity strappings, continuous filament high speed lines (BCF/CF), partially oriented yarn (POY), technical nonwoven and low title hygienic fabrics, spunbonded and staple fibers
- Healthcare – Polypropylene homopolymers, copolymers and random copolymers suitable for extrusion, blow moulding and injection moulding and compliable to USP 87, USP 88, ISO 10993-4, 5, 10 and 11. Our portfolio of materials are resistant to autoclave, beta, gamma and ethylene oxide (EtO) sterilization without affecting their aesthetic or mechanical properties
With our comprehensive portfolio of phthalate free polypropylenes, we are expanding our customers' capabilities to meet the demands of increasingly phthalate sensitive markets, without compromising the health and safety of the end users.
