Envalior
Founded in 2023, Envalior is a leading global provider of engineering materials. The company combines the expertise of DSM Engineering Materials and LANXESS High Performance Materials and offers a broad portfolio of material solutions for a range of industrial applications. LANXESS, until 2005 part of BAYER AG, and ALBIS have worked together in the field of engineering thermoplastics since 1966. The cooperation is based on three business areas: the distribution of Envalior products in numerous European countries and China, the tolling business, and the licensing business for Durethan® and Pocan®. Envalior offers selected Durethan® and Pocan® product variants containing bio-based, bio-circular and/or recycled raw material content. For certain mass-balanced variants, the corresponding raw material content may be allocated using the mass-balance approach in accordance with the applicable certification requirements. Envalior further states that certain product variants may have a lower Product Carbon Footprint than the corresponding fossil-based standard grades. ® Registered Trademark of Envalior
Products
Durethan® A, B
Durethan® is the brand name Envalior uses for its polyamide 6 and polyamide 66 products. Polyamides are semi-crystalline plastics whose combination of characteristics makes them particularly suitable for technical applications.
These include: high mechanical strength and rigidity; good electrical insulation capabilities; high heat and chemical resistance; good sliding properties; wear resistance; and good noise and vibration damping. They also have exceptional processability.

Profile & Characteristics
- High-gloss or structured surface quality (depending on tool surface, excellent reproduction of detail)
- High rigidity (especially fiber glass reinforced models; tensile modulus: 1,300 to around 20,000 MPa (depending on moisture levels))
- High shock and breakage resistance - depends on type and moisture levels; elastomer modification provides good toughness even with low moisture levels, and if necessary at low temperatures
- High dynamic load bearing capacity
- Good stress fracture behavior
- High heat resistance - short-term: 170 to 200 °C, long-term: 110 to 200 °C
- High wear resistance
- Good chemical resistance, especially to fuels, lubricants, solvents, and cleaning agents
- Good mechanical and acoustic damping, good sliding properties, good gas barrier properties (film types)
