What are the differences between PP regranulate and granulate?

Polypropylene (PP) is one of the most commonly used thermoplastic materials. It is applied in numerous industries such as automotive, medical, and packaging.

PP Granules – Pure Raw Material

PP granules are the primary material obtained from processing polypropylene in its purest form. Thanks to their predictable mechanical, chemical, and thermal properties, PP granules are used to produce a variety of products – from simple packaging to advanced industrial components. The most important feature of granules is that they have not been previously used.

PP Regranulate – Recycled Material

PP regranulate is a material produced from recycling polypropylene waste. This process involves shredding the waste, cleaning it, and then processing it into new granules ready for reuse. While regranulate has slightly lower mechanical properties compared to virgin granules, it is more environmentally friendly and cost-effective.

Properties and Material Quality

PP granules are characterized by high quality and stability. In contrast, the quality of regranulate depends on the initial raw material and the recycling technology. Although it may sometimes have lower durability or chemical resistance, advancements in recycling technology are continuously improving its properties. As a result, regranulate is used in products such as disposable packaging, toys, and construction components.

Ecology and Savings

PP regranulate helps reduce waste and lower raw material consumption, supporting the concept of a circular economy. Despite its slightly reduced performance, its lower price and smaller environmental impact make it an increasingly popular choice across many sectors.
