Current developments and predictions show clearly that an easing of the Polyamide (PA) 66 supply issue is not in sight. In 2019 the market remains in a critical situation driven by lack of availability, combined with continuously increasing demand and prices. Innovative materials and creative developers are needed to help overcome the disruptive factors in the PA66 global supply chain, and to find long-term alternatives.
Using it's internal compound development capabilities Brenntag, the global market leader in chemical distribution, has introduced two PA6 based products designed as substitutes for PA66. Taking account of specific differences and user needs, PA66 and PA6 have much in common and there is certainly potential for adequate substitution.
Brenntag's NYLAFORCE® dynamic range consists of compounds based on PA6. They have been developed specifically for demanding technical applications. The high-performance engineering polymers combine high product efficiency with very good processing properties, outstanding surface quality and universal application. The mechanical properties of the products are particularly impressive, and are quite exceptional for highly reinforced polyamides.
For example, the tensile strength of NYLAFORCE® dynamic B 50, which is reinforced with 50% glass fibres, is approx. 10% above the figure for a standard PA66 GF 50, and the conditioned value is comparable. In the tensile test, NYLAFORCE® dynamic B 60, because of its higher glass fibre content of 60%, has even better mechanical properties, also at higher temperatures.
NYLAFORCE® dynamic B compounds also boast a broad processing window and high dimensional stability. All these properties make the materials a very good alternative to PA66 for applications and components in automotive, building and construction, E&E etc.
In principle, other polymers apart from PA6 such as PPS or PBT are also suitable for modification. Brenntag works with a wide selection of base polymers, additives, fillers and reinforcing materials, developing customised compounds via a customer oriented approach.
