The sale and manufacture polyamide resins covers all major sectors: automotive, electrical, appliances, mechanics, textiles and clothing.
The PA66 is used in the production of fibers, films and extruded sheets, pipes, hollow bodies obtained by means of blow molding, gears, bearings, toothed wheels, eccentric, nuts and bolts, bushings, rivets, kitchen utensils, bodies of electrical equipment, connectors , parts for under the hood applications including covers of radiators and cooling fans.
In the sale and PA66 production it exists today a real price wars: the cost of polyamides does nothing but swing and the same plastics industry is today in difficulty.
However Poliblend manages to maintain a competitive product offering and at the same time make its way as leader in the field of technical polymers.
In the PA66 production and in general in the Polymer Technical sector, the foresight of Poliblend was the introduction of products of the same level of the most qualified competitors, but at a lower cost and with faster delivery.
In the sale of PA66 it’s necessary to be timely to buy and meanwhile pay attention to the inventories.
Poliblend has always aimed to preserve the flexibility of a small company, even when the size has grown and has become the leader of a greater reality.
The sales and production of PA66, the virgin polymer base, is the core business of Poliblend; in standard version and in the loaded, colored, self-extinguishing, elastomeric versions.
The production of PA66 and PA6, PA12, is however not the only Poliblend activity; The product range also includes the POM acetal resins (homopolymer and copolymer), PBT (polybutylene terephthalate), a crystalline product suitable to meet several technical and finally the polycarbonate applications in different formulation versions.
In the production of PA66 and other polyamides Poliblend has also developed interesting new formulations, which have already found a good success. For example, cadmium-free products with high thermal characteristics and colorimetric stability during processing, which represent a technological achievement of a certain level.
In the sale of PA66 and all the other materials, the Poliblend peculiarity is to follow the customer in the particular applications, through the development of solutions able to meet specific needs, for example by introducing changes which render the product suitable to be used with a particular type of mold.
The PA66 resin, often called Nylon 6,6 was synthesized for the first time in 1936 and is one of the most widespread polyamides.
The PA66 is the aliphatic polyamide which presents higher mechanical strength characteristics, has a good abrasion resistance with low coefficient of friction and a good resistance to organic solvents.
Requires short molding cycles and, through the copolymerization, and the charge of fibers, rubber or minerals, you can get degrees with a wide distribution of properties.
The resistance to the system at low temperatures is higher than the one of the acetal resins, PBT or PA6, also shows good resistance to fatigue.
The comparison is always made with PA6, although generally the choice between the two polyamides is carried out for reasons other than technological ones (availability, price); the PA 66 is relatively more difficult to print due to the low melt viscosity.
Other common disadvantages of the polyamides are the absorption of H²O (8% to saturation) and the shrinkage during the molding that may result in significant warpage
