Technical Properties of HDPE Regranulate

recycled HDPE regranulate is characterised by technical specifications that place it among the most widely used industrial materials. Its strength and ability to adapt to different processing technologies make it highly valued both in small businesses and large manufacturing plants.

Thermal Stability and Chemical Resistance

• High thermal stability: An operating temperature range from -40°C to 120°C allows for wide use of recycled HDPE regranulate in processes such as injection moulding, extrusion and blow moulding.
• Universal chemical resistance: Due to its resistance to acids, bases and organic solvents, the regranulate is widely used in the production of chemical packaging and industrial tanks.

MFI Parameters as a Key Technical Aspect

recycled HDPE regranulates can be easily adjusted to specific processes:

• Low MFI: Excellent for pipe and profile extrusion technologies where high material durability is required.
• Medium and high MFI: An ideal solution for the packaging industry and for injection moulding of small technical components.

Equivalence to Virgin Materials

Although the regranulate comes from recycling, its properties are comparable to virgin HDPE, which ensures competitiveness in many demanding applications. Black HDPE regranulate additionally stands out with its resistance to UV radiation, making it an unrivalled solution for outdoor use.

Production Process of HDPE Regranulate

The production of high-quality regranulate requires modern technologies and specialist know-how. Precise processing of HDPE waste makes it possible to create materials that meet the highest technical and environmental standards.

Key Stages

1. Material selection: Raw materials come from both PCR and PIR sources, which allows for diverse applications and an excellent basis for recycling.
2. Cleaning and granulation: Removal of contaminants and thermal processing ensure homogeneity and high accuracy of technical parameters.
3. Quality control: Advanced laboratories monitor regranulate characteristics, including density, MFI and ash content, eliminating the risk of defects in the final product.

Applications of HDPE Regranulate

The versatility of HDPE regranulate enables its use across many sectors of the economy:

• Construction: Used in the production of sewer pipes, protective plates and drainage systems.
• Packaging: Production of robust industrial and reusable containers that help reduce operating costs.
• Technical components: Used in industries that require precision and dimensional stability, such as automotive and household appliances.

Environmental and Economic Benefits

HDPE regranulate is a symbol of sustainable development, helping to minimise the impact of industry on the natural environment:

• CO₂ reduction: Regranulate production can reduce CO₂ emissions by up to 75% compared to virgin HDPE.
• Waste reduction: Processing HDPE waste reduces the need for landfilling and supports the circular economy.

Implementation examples, such as the production of automotive parts or transport packaging, show how versatile and functional HDPE regranulate is. Companies using this material not only optimise production, but also support the achievement of ESG-related goals.

Summary

HDPE regranulate is an innovative solution that combines outstanding technical properties with unprecedented environmental benefits. Its production is in line with the principles of the circular economy, enabling economical and sustainable use of existing resources.

As a leading material for responsible industry, HDPE regranulate offers financial savings, reduced CO₂ emissions and wide technological potential. It is a raw material that not only supports innovation, but above all enables concrete action for environmental protection. By using it, companies invest in a durable and responsible future.

Recycled HDPE regranulate – frequently asked questions

What is the difference between recycled HDPE and virgin HDPE?

Recycled HDPE regranulate is produced from sorted post-consumer and post-industrial polyethylene waste, whereas virgin HDPE is made from crude oil. In most technical applications recycled HDPE offers comparable density, melt flow index and impact resistance at a noticeably lower price and with a far smaller carbon footprint – production of recycled HDPE can cut CO₂ emissions by up to 75% versus virgin material.

Which colours of recycled HDPE regranulate are available?

ASEO supplies recycled HDPE in three colour variants: blue, transparent (natural) and black. Blue recycled HDPE is preferred for containers and bottles, transparent for food-contact and cosmetics packaging, and black recycled HDPE for automotive, construction and technical parts thanks to its UV resistance.

What MFI and density can I expect from recycled HDPE?

Typical recycled HDPE regranulate from ASEO has an MFI in the 0.3–8 g/10 min range (190 °C / 2.16 kg, ISO 1133) and a density of 0.94–0.97 g/cm³ (ISO 1183). The flow rate can be adjusted to your process on request, from low-MFI grades for pipe extrusion to higher-MFI grades for injection moulding.

Is recycled HDPE suitable for pressure pipes?

Yes. Low-MFI recycled HDPE is widely used in the extrusion of pressure water and sewage pipes, corrugated SPIRO pipes and high-voltage cable conduits, thanks to its chemical resistance and flexibility. Each batch is tested so the recycled HDPE performs on par with virgin material in demanding installations.

How is the quality of recycled HDPE controlled?

Every batch is laboratory-tested for MFI, density, ash content and contamination, and documented with a technical data sheet. ASEO holds RecyClass process certification (EN 15343:2007, ISO 22095:2020) and the BRCGS Global Standard for Packaging Materials. Full details are on the permits and certificates page.

Recycled HDPE vs virgin HDPE – a practical comparison for buyers

For most industrial buyers the decision is not whether recycled HDPE can replace virgin polyethylene, but in which applications the substitution is fully transparent. The table below summarises how recycled HDPE regranulate compares with virgin HDPE across the parameters that matter in procurement and processing.

Criterion	Recycled HDPE (PCR/PIR)	Virgin HDPE
Origin	Sorted post-consumer / post-industrial waste	Crude oil / natural gas
Price	Typically 20–40% lower	Reference (higher)
CO₂ footprint	Up to 75% lower	Reference (higher)
PPWR recycled-content quota	Counts towards the quota	Does not count
Batch consistency	Stabilised by homogenisation & melt filtration	Very high

In practice, recycled HDPE is the default choice for extruded pipes, profiles, geomembranes and industrial packaging, where its mechanical strength and chemical resistance match virgin material while delivering a lower unit cost. Virgin HDPE retains an edge only in a narrow set of applications with the strictest optical or food-contact requirements. With the PPWR recycled-content quotas approaching, switching part of the feedstock to recycled HDPE now also protects buyers against the supply squeeze and price increases expected before 2030. Black recycled HDPE, in particular, combines UV resistance with the most attractive raw-material cost, which is why it dominates outdoor and construction applications.
