Frequently asked questions (FAQ)
ENTRON eco Granulate

PA6 and PA6.6 differ in their chemical structure. PA6 has a lower crystallinity, which results in improved toughness and processing capability. PA6.6 has a higher crystallinity, which results in better strength, rigidity, and thermal stability. PA6 is well suited for impact-resistant applications, while PA6.6 is ideal for heat-resistant and high-strength applications.
PA6 provides good toughness, flexibility, and process capability. It is particularly resistant to impact and is easy to extrude and injection mould. PA6.6 offers greater strength and rigidity thanks to its higher crystallinity. It can withstand higher temperatures and is therefore ideal for heat-resistant applications. PA6.6 is also more chemically resistant, which increases its longevity in demanding environments.
PA6 has a melting temperature of around 220°C and retains its mechanical properties well at low temperatures. It is less crystalline, which results in a lower heat deflection temperature compared to PA6.6. PA6.6 has a higher melting temperature of around 260°C, which makes it suitable for applications requiring greater thermal stability. It features a higher heat deflection temperature and maintains its strength and stiffness more effectively at higher temperatures.
PA6 is resistant to many chemicals, including oils, greases, and solvents. It shows good resistance to alcohols and ketones, but can be vulnerable to strong acids and bases. PA6.6 provides even greater chemical resistance and is particularly resistant to many solvents, greases, and oils.
Recycled polyamide provides numerous benefits (including the reduction of CO₂ emissions), as the use of recycled materials reduces the need for new raw materials and consequently lessens the environmental impact. It contributes to the circular economy by transforming waste into valuable new materials. Recycled polyamide offers similar mechanical and chemical properties to virgin polyamide, making it suitable for a wide range of applications. Furthermore, using recycled materials promotes resource conservation and reduces waste.
The main difference between virgin and recycled polyamide is their origin. Virgin polyamide is made from petrochemical raw materials, while recycled polyamide comes from waste. The waste is divided into post-industrial and post-consumer grades, with Enneatech specialising in industrial waste. Undergoing a sophisticated recycling process, recycled polyamide has the same quality as virgin material. It offers similar mechanical and chemical properties while contributing to sustainability by reducing waste and conserving resources. Recycled polyamide therefore offers an environmentally friendly alternative without compromising on quality.

The difference between polyamide compounds and polyamide raw polymers lies in their composition and application.

ENTRON eco granules are a raw polymer (basic polyamide) that is produced directly from the extrusion of polyamide waste (PIR). These raw polymers have the basic properties of polyamide, such as high strength, good abrasion resistance and chemical resistance, but without modifications or additives. They are often used as a starting material for compounding or for unmodified plastic parts. They can be used in a wide range of applications, but without further modification they are often not ideal for specific, application-related requirements.

ENTRON eco compounds are polyamide granulates that have been modified with various additives or fillers to improve certain properties or give them new properties. Compounds can have customised properties such as increased stiffness, improved thermal conductivity, reduced moisture absorption, increased impact strength, flame retardant properties or improved processability. They are particularly useful for specialised applications where specific mechanical, thermal or electrical properties are required. Examples include automotive parts, electrical and electronic components, industrial equipment and consumer goods.

Summarised
ENTRON eco granulates (raw polymers) are unmodified basic polyamides.

ENTRON eco compounds are modified versions of the raw polyamide polymers, optimised for special requirements and applications.

Recycled polyamide is versatile and can be used in many industries. In the automotive industry, it is used to manufacture components such as air intake manifolds, engine covers, and fuel systems. Recycled polyamide is also used in electrical engineering for housings and insulation, in the construction industry for various construction materials, and in the furniture industry for hard-wearing fabrics and components.
Undergoing a sophisticated recycling process, recycled polyamide has the same quality as virgin material. High-quality recycling processes and the careful selection of raw materials ensure that recycled polyamide offers similar mechanical and chemical properties to virgin polyamide. Quality assurance measures and certifications help to ensure the recycled polyamide’s high level of quality. One major difference to virgin materials are the greater specified tolerances, e.g. regarding viscosity.
By utilising innovative recycling technologies and producing high-quality recycled polyamides, ENNEATECH plays a leading role in the field of recycled polyamide. The company uses mainly synthetic fibres from the high-end textile industry as a raw material source, which helps to reduce CO₂ emissions and conserve natural resources. ENNEATECH promotes the circular economy by reusing materials and is committed to sustainable development goals. ENNEATECH also ensures that the quality of the recycled polyamide meets customer requirements.

Recycled polyamide can receive various certificates that confirm its quality and sustainability. These include:

  • Environmental Product Declaration (EPD): This certification provides transparent information concerning the environmental impact of a product over its entire life cycle
  • Product Carbon Footprint (PCF): This certificate measures the CO₂ emissions of a product.
  • ISO certifications: These include various standards, such as ISO 14001 for environmental management and ISO 50001 for energy management.
  • These certificates help to guarantee the quality and environmental compatibility of recycled polyamide — and to present it transparently.
ENNEATECH’s primary sustainability goals include promoting sustainable consumption and production, reducing CO₂ emissions, and using clean energy sources. ENNEATECH uses innovative recycling technologies and sustainable production methods to minimise the environmental impact of its products. The company is also actively involved in the development and implementation of standards and practices that support the circular economy and reduce environmental impact. Through these measures, ENNEATECH contributes to a more sustainable plastics industry.
ENNEATECH uses mechanical recycling to produce high-quality recycled polyamides. The fibre waste is shredded and then formed into pellets on an extrusion line. The moisture is removed and the melt is filtered, thus enabling efficient and environmentally friendly processing. These automated systems improve the quality and consistency of the recycled materials and help to reduce CO₂ emissions by using sustainable raw materials from the textile industry.
ENNEATECH optimises its energy consumption through extensive energy management measures. These include using green electricity and its own photovoltaic system, as well as installing energy-efficient electric motors and compressors. The company has also introduced an automated line management system and plans to utilise waste heat to heat its production facilities. These measures contribute to reducing energy consumption and CO₂ emissions while supporting ENNEATECH’s sustainability goals.
ENNEATECH promotes sustainable development in the plastics industry through the use of recycled raw materials and the development of high-quality polyamides. The company works closely with universities and research institutes to develop innovative recycling technologies and sustainable production methods. ENNEATECH is committed to complying with environmental and energy management standards and implementing quality standards and norms for recycled plastics. Through these measures, ENNEATECH contributes to reducing environmental pollution and promoting the circular economy.
ENNEATECH ensures transparency with regard to environmental impact by providing detailed information on the CO₂ emissions of its products. This is realised through independent testing and the use of Environmental Product Declarations (EPD) and Product Carbon Footprints (PCF). Both methods provide comprehensive insights into the environmental impact of products, with the EPD based on a complete life cycle assessment that includes all relevant potential harmful effects on the environmental media of soil, air, and water. This transparency helps customers make informed decisions regarding the products’ environmental compatibility.
DIN SPEC 91481 supports recycling by defining requirements for the classification of recycled plastics and plastic waste from polyamides according to data quality levels. These standards create a consistent language and transparency that facilitate the trade and use of polyamide recyclates. A digital product passport makes the life cycle of recyclates transparent and enables standardised data collection, storage and transfer. This promotes acceptance and demand for recycled materials and supports the circular economy within the plastics industry.
