Polypropylene is a class 5 recyclable packaging material which is excellent for usage in secondary resin markets. It is an eco-friendly material, it has a low carbon footprint. And the best part of this resource is that nothing is mined or farmed to create it. It is a by-product of the petroleum and natural gas refinery industry. It can be used to make modern plastic chairs – polypropylene is solid and can stand up to forces being applied without it bending, breaking, shattering or deforming in any way. This resource can also be used to make recycled plastic parking stops – the newest technology in the plastics industry made of an injection molded polypropylene skin filled with expanded polypropylene beads is used. The parking stop is easily installable by a single person and durable enough to stand up to extreme temperatures and everyday wear and tear. Another application of this material is for creating landscaping material like a Polypropylene Ground Cover which offers unbeatable UV protection to keep weeds in the dark. Polypropylene is also used in automotive equipment, caps and closures, consumer goods, houseware parts, garden furniture, and storage containers.
Merits of using Polypropylene
- A versatile thermoplastic material, Polypropylene (PP) is well-matched with many processing techniques and used in many profitable applications in the area of recycled packaging.
- PP can be found in a broad range of melt flow rates, fluctuating between 0.3 to over 1000 g/10 min, and it is easily recyclable. The material can be processed in various ways including injection molding, blow molding, extrusion, blown, cast film, and thermoforming.
- PP and PE together ingest the minimum energy during the production process and give out the lowest carbon dioxide emissions as compared to other plastics. On account of its lower density swapping to PP brings down the absolute amount of waste.
- Parts made from PP can be recycled a couple of times in a wide variety of applications before incineration is necessary. And at the time of incineration, one can regain more energy from PP during incineration than from any other comparable plastic. It also flows more easily as it degrades, without cross linking, gel forming or off-gassing.
Other benefits include chemical and thermal resistance, excellent moisture and oxygen barrier properties, hot fill and retort capable, sealable and microwavable.
The Power of Polypropylene
Polypropylene produces less solid waste by weight than PET, PS or PVC. Thus many recycling applications exist for Polypropylene: battery cases, paint cans, home storage, flower pots, pallets, crates, composite lumber, and more. In the US, out of the 51 largest US municipalities of the state, 44 collect polypropylene.
Polypropylene and high-density polyethylene (HDPE) produce significantly less CO2 equivalents by weight than PET, PS, and PVC. And Polypropylene parts can be 100% recycled for various useful purposes. A market for recycled PP (rPP) exist in an extensive range of products such as automotive applications, buckets, caps and closures, garden furniture, pallets, pipes, and more.
