Recycled Polyamide (PA6, PA66, PA12)
Excellent performance to cost ratio and a high-quality recyclate: R-PA
Polyamide (PA) covers a family of various PA types and offers an excellent cost to performance ratio. Virgin PA is commonly used in automotive, electronics, packaging, and textile applications, while recycled PA is mostly used in automotive parts, flooring materials, composite lumbers, and house textiles.

Recycled PA applications
What products can be made of recycled PA?
PA has high strength, toughness, and stiffness, good abrasion resistance and chemical resistance as well as a high barrier to oxygen, fats, and oils. On the other hand, PA is a hydrophilic plastic that absorbs water. How pronounced this property is depends on the type of PA used and must be taken into account during processing and application.
Overall, PA offers an excellent price-performance ratio and is usually processed by injection molding, laser sintering, or used for the production of films and fibers. Depending on the type, PA is used as an unfilled resin or with fillers or reinforcing materials (minerals, glass beads, glass fibers) to produce plastic parts for the automotive, electrical, and electronics or general industry.
Typical applications are motor covers, drive trains, switches, industrial CEE connectors, power tools, railway pads, ski fasteners, castors, connectors, housings, fasteners, screw anchors, air duct systems, oil sensors, fastening systems, casings, composite wood, technical or apparel textiles, insulating panels, etc. Besides non-food grades, in some cases, PA can also be used in food-grade packaging.

PA waste feedstock
Which sources can be used for PA recycling?
The PA raw materials are usually non-food grade waste. The post-industrial feedstock for various PA types mostly comprises pre-sorted waste produced during the manufacture of PA-based plastic articles by injection molding. This feedstock often contains PA with varying levels of fillers and reinforcing materials in the range of 15 to 50 wt%. Other sources include fiber waste, chips from cast polyamides (PA6, PA12), and unfilled materials from extrusion processing (e.g. packaging films).
Normally, unfilled or filled/reinforced PA recyclates are available as regrind, regranulate, or recompound.
