Akulon® - PA6 & PA66

The versatile high performance polyamide

Akulon is our family of high performance polyamide 6 and polyamide 66 materials, used by customers across the world in applications ranging from automotive, electronics & electrical, to furniture and packaging. We offer Akulon grades for injection molding, blow molding and extrusion (including barrier film, stock shapes, convoluted tubes, and mono and multi filament).

In molded parts the material offers an excellent balance of easy design and processing with outstanding mechanical properties over a wide temperature range and in diverse conditions. Meanwhile for extrusion the strength, resilience and easy processing of Akulon sets the market standards.

Akulon Ultraflow: Going with the flow

Manufacturers looking to improve flow and boost cycle time with excellent surface appearance are increasingly looking to Akulon Ultraflow. This is easy-to-process polyamide 6 offers up to 80% improved flow and a 40% reduction in injection molding cycle times with no significant effect on mechanical properties compared to standard polyamide 6 grades.

Today, Akulon Ultraflow is being used in many demanding applications like engine covers, intake manifolds, automotive exterior mirror shells, furniture, and power tools. The bright science behind the faster flow of Akulon Ultraflow equates to lower system costs – and not just via faster cycle times.

Akulon Diablo

Akulon Diablo is our high heat resistant polyamide 6/66, ideal for metal replacement in Under-the-Hood applications up to 220°C. We created Akulon Diablo as a material to help customers tackle the ever-challenging temperature range within smaller, hotter, turbo engines. As a result the latest grade Akulon Diablo HDT2500 delivers a 3,000 hour continuous use temperature of up to 220°C, with a significant improved HDT value.

Akulon Diablo is ideal for metal-to-plastic replacement in components for air intake systems ranging from charge air cooler end caps, to air intake manifolds, to air intake ducts, turbo exhaust resonators and engine covers. With its reduced weight this material reduces both fuel consumption and resultant carbon emissions – good for people, planet and profit.

Fuel Lock: Big Evaporative Emissions Reductions for Small Engines

Born out of the need for a more eco-friendly product after stricter emissions regulations, Akulon® Fuel Lock emerged as a functional replacement for the HDPE materials commonly used for small-engine fuel tanks.

With small-engine emissions projected to reach more than twice those of light-duty passenger cars by 2031, DSM seized the opportunity to develop a novel material that decreases emissions while maintaining durability.

Fuel tanks made with Akulon Fuel Lock, a low-permeation material, significantly lower hydrocarbon emissions while also meeting mechanical requirements, such as high-impact performance at temperatures as low as -40° C.

Akulon® RePurposed: The versatile, high performance polyamide, based on recycled resources

DSM uses discarded fishing nets as the source to produce the recycle-based polyamide Akulon®Repurposed. DSM uses material recovered from discarded fishing nets collected along the coastlines of India, which are treated and upcycled using local labor, before being compounded.

With this new product line DSM contributes to cleaner oceans as instead of disposing discarded fishing nets on the beach or in the sea these are collected for recycling purposes. The product also has an extended positive social impact in terms of job creation and the development of new skills and knowledge of people working in the supply chain (i.e. collecting, sorting, cleaning and processing fishing nets).

UD Tapes: Light weighting through composites

A family of polyamide-based UD tapes with endless carbon or glass fiber reinforcements are light weight alternatives to metals in several automotive applications. UD tapes, tape-based 2D fabrics, and cross plies are used in structural and semi-structural applications, and in the selective reinforcement of injection molded parts.

Featured customer applications

Refrigerator hinge

Industrial equipment | Material / fluid handling

Akulon® PA6 in this hinge reduces the cost and procissing steps compared to metal; PA6 offers the required mechanical properties and thoughness to meet the required high performance and quality

Agricultural Films

Industrial equipment | Agriculture

Akulon® PA6 F136-C allows for reliable solutions due to its optimized mechanical strength and due to its low permeation to methyl bromide compared to conventional materials; Akulon® PA6 F136-C allows for cost effective solutions due to an improved bubble stability, an optimized processing efficiency

Breathable Films for Food Packaging

Consumer goods | Food Packaging

Arnitel® TPC allows for reliable solutions, since it yields a breathable film that balances the application-specific gas mixture of O2 and CO₂, and the moisture inside the package

Engine Covers

Automotive | Drivetrain | Transmission

Akulon® PA6 allows for reliable solutions due to high temperature resistance (better than PP), great surface appearance (better than PA66) and low warpage levels; Akulon® Ultraflow grades allow even for more cost effectiveness due to 25% cycle time advantage and due to high flowability enabling thinner walled designs
