Nylon 66: Specialist Grades

Nylon 66

Nylon 66 is a semi-crystalline polyamide (PA) with good rigidity, hardness, abrasion resistance and thermal dimensional stability. It also shows outstanding wear resistance and low frictional properties. Compared with Nylon 6, Nylon 66 has a higher mechanical strength, stiffness, creep resistance and heat and wear resistance, but its impact strength and mechanical damping ability are reduced.

Whilst these properties make Nylon 66 a great choice for an engineering plastic, Quadrant have created a range of specialist Nylon 66 materials with added ingredients to provide enhanced properties compared to standard grade Nylon 66. Many of these specialist Nylon 66 materials have been developed with specific applications in mind.  


Nylatron® GS

The addition of MoS2 renders this material somewhat stiffer, harder and dimensionally more stable than Ertalon 66 SA, but results in some loss of impact strength. The nucleating effect of the molybdenum disulphide results in an improved crystalline structure enhancing bearing and wear properties.


Ertalon® 66 GF30

Compared with virgin PA 66, this 30% glass fibre reinforced, and heat stabilized nylon grade offers increased strength, stiffness, creep resistance and dimensional stability whilst retaining an excellent wear resistance. It also allows higher maximum service temperatures.


Nylatron® 66 SA FR

This grade has been developed to fulfil the requirements as set out in the test program conducted on plastic material to measure flammability characteristics, which determines the material's tendency either to extinguish or to spread the flame once the specimen has been ignited. This program is described in UL 94 and this product grade fulfils the V-0 criteria as from 1 mm thickness. It also fulfils the requirements as set out in EN 45545-2 regulation - a standard specific for railway applications - fire protection on railway vehicles.


Nylatron® 66 SA FST

For interior applications in aircraft materials must meet various requirements to be recognised. They must be lightweight, meet engineering demands, wear and design requirements, and in addition have fire-safety characteristics that meet aviation regulations and standards like FAR 25.853. Quadrant’s new Nylatron® FST is a specifically designed polymer solution for aircraft interior applications. Its unique features make it the first engineering plastic product of its kind available as semi-finished shapes (rods and sheets). Fire, smoke and toxicity (FST) retardant capabilities enable Nylatron® FST to withstand extreme temperatures up to 175 ºC. The material is particularly suitable for any kind of application where metal parts (e. g. brackets, seal bushings, slide rails and duct seals) or high-performance polymers have traditionally been specified. Nylatron® FST has passed tests to comply with Federal Aviation Regulations FAR 25.853 – the first engineering plastic shape to achieve this standard and offering engineers a safe material solution.
