Polyamide Market

The demand from the automotive industry (a key driving force for the polyamide market) is only expected to increase with the boom in electric vehicle (EV) production. Due to the clear direction of car makers to increase energy efficient and efficient performance, demand for replacement of heavy metallic parts in automobiles with that of lightweight materials is predicted to increase. Having excellent weight-to- strength ratio, high-thermal stability combined with resistance to chemicals and wearability PA6, PA66, and some speciality grades such as PPA, are being increasingly used in the substitution of light weight materials. In addition to the advantages outlined for electric cars, polyamides have been adopted by EV manufactures as the preferred material for all under-the-hood parts, batteries and battery modules, and connection systems. Efforts to reduce weight in an electric vehicle are essential to extend the vehicle‘s battery span and enhance its driving range without compromising on safety and structural integrity; adding polyamides allows a light weight vehicle without sacrificing performance. As electric vehicle production expands in Asia Pacific, Europe and North America, these patterns of premium polyamide use are expected to be reinforced and expand across new car niches.

A significant factor restraining the growth of the polyamide market is the fact that a large number of other materials (including some which are functionally equivalent, and some that have even better physical properties), are available to substitute polyamides, at a lower cost than a polyamide. In many end-use applications, polyesters (PBT, PET), polyurethanes, polyolefins, and even higher performing composite materials are becoming more and more popular substitutes for polyamides. These substitute materials offer enhanced performance, (through better physical properties or lower Moisture absorption or better dimensional stability or better processability, depending on the end use requirement). For example, for electrical components as well as automotive components, PBT and polypropylene are by far the most preferred materials due to their low cost and suitable thermal resistance. Furthermore, in the textile and flexible packaging fields, polyesters and polyolefins are their main competitors with respect to polyamide fibers and films respectively, especially where competitive prices are concerned. Emerging bio-based and biodegradable polymer markets, such as those based on polylactic acid, and thermoplastic starches used in sustainable packaging, are also not enablers of polyamide consumption. With continual material innovations and relatively good substitute polymer performances, the polyamides face significant challenges in many applications, which restrict it from entering other cost-sensitive markets.

Investment and R&D in bio-based polyamides are setting promising growth perspectives in polyamide as the industries evolve toward sustainable, eco-friendly materials. Bio-based polyamides are said to have the same chemistry as other polyamide chemically, but from renewable sources (using plant oils, et cetera) so they can provide numerous advantages, including lower carbon footprint, lower demand for fossil fuels, etc., and excellent performance, durability, flexibility, heat and chemical resistance. An increase in R&D for enhancing the processing, cost and scope is evident while an increase in the investment to improve the overall production capacity and establish an entire supply chain for renewable monomers and bio-based polyamide resin is also known. Use in textiles, automobiles, electronics and medical devices continues to increase, in part due to performance advantages, but partly because of environmental benefits. Increasingly strict environmental regulations and more environmentally conscious consumers are helping to spur this development and adoption of these greener alternatives, which offer the benefit of being greener to the consumer and the manufacturer while also help to meet climate change commitments. Bio-based polyamides have become an excellent means by which polyamide producers can innovate, high-grade their image and stay on an upward growth trend, and look for profitability, for years to come.

Challenges to the development of the polyamide market are about rising raw prices and the wider pressures of plastics environmental risk. Polyamides especially the more prevalent types like PA6 and PA66 rely on petrochemically derived raw materials (e.g caprolactam, adipic acid and hexamethylene diamine) where flactuations in global crude-oil trends, geopolitics and supply chain problems places pressure on the prices of those raw materials which impacts the cost of polyamides and where cost pressures are absorbed by the manufacturers of polyamides they find it more difficult to hold their prices and margins steady. This is further compounded by polyamides being a finite, non-biodegradable resource which when placed in waste and not properly recycled adds to plastics waste residue. An increasing awareness of the risks to the environment from plastics residue and more increasingly stringent regulations on plastics with ease of disposal (such as single use plastics) mean end-use industries are reconsiderating their choice of polymer material. Therefore it is not surprising that many companies are switching to lower impact alternatives like bio-renewable, recyclable or biodegradable polymers. This combination pushes the wider market development of polyamides back. To work through these challenges industry players should have an invested interest into sustainable innovations, plastic recycling solutions and secure raw material supplies.
