Product Profile:
- Broadest size range availability
- Good mechanical and electrical properties
- Ideal balance of strength and toughness
- Many grade options: FDA compliant, Internally lubricated, Heat stabilized
- Cast as finished parts and near net shapes (nylon 6)
Nylon's toughness, low coefficient of friction and good abrasion resistance make it an ideal replacement for a wide variety of materials from metal to rubber. It weighs only 1/7 as much as bronze. Using nylon reduces
lubrication requirements, eliminates galling, corrosion and pilferage problems, and improves wear resistance and sound dampening characteristics. Nylon has a proven record of outstanding service in a multitude of parts for such diverse fields as paper, textiles, electronics, construction, mining, metalworking, aircraft, food and material handling.
Nylon is easily fabricated into precision parts using standard metalworking equipment. Its good property profile combined with a broad size range availability have made the material very popular since we first
introduced nylon stock shapes in 1946. Today, a variety of extruded and cast nylon grades are available to match specific application demands.
Since nylons are frequently used for wear applications, Table 2 and Figure 9 are provided to assist designers with material selection.
Nylon 6/6 grades are extruded and available in the following cross sections: rod, tubing and plate.
Nylon 6 products are cast from Quadrant caprolactam — providing you with single source traceability and quality control from raw material to finished product. It is typically supplied in rod, plate, tubular bar or custom shapes including near net castings.
NEW: Compared with conventional nylons, Nylatron® 4.6 features a better retention of stiffness and creep resistance over a wide range of temperatures as well as superior heat aging resistance. Therefore, applications for Nylatron® 4.6 are situated in the "higher temperature area" (175 - 300°F) where stiffness, creep resistance, heat aging resistance, fatigue strength and wear resistance of PA 6, PA 66, POM and PET fall short.

Nylon 101
Of all the unmodified nylons, Nylon 101 is the strongest, most rigid and has one of the highest melting points. It is
commonly specified for screw machined electrical insulators and food contact parts.
It is stocked in both natural and black. Other colors are available on a custom basis. Nylon 101 natural is FDA, USDA, NSF, and 3A-Dairy compliant.

MC® 907 Nylon
Unmodified type 6 nylon offering the highest strength and hardness of the nylon 6 grades. MC 907 natural is FDA, USDA and 3A-Dairy compliant. It is off-white and primarily used for food contact parts. |
| Heat resistant grades |
Nylatron® 4.6
Offers superior heat aging and creep resistance and retention of stiffness up to 300°F. It is reddish brown in color and used where PA 6, PA 66, POM and PET fall short. |
MC® 901 Nylon
Heat stabilized nylon offering long-term thermal stability to 260°F. It is blue in color and used in a variety of bearing and structural applications such as wheels, gears, and custom parts. |
| For improved load bearing capability |
Nylatron® GS Nylon
Molybdenum disulphide (MoS2) filled nylon offering improved strength and rigidity. With a lower coefficient of linear thermal expansion than Nylon 101, Nylatron GS parts maintain better fit and clearances, and have less tendency to seize as bearings. |
Nylatron® GSM Nylon
Nylatron GSM contains finely divided particles of molybdenum disulphide (MoS2) to enhance its load bearing capabilities while maintaining the impact resistance inherent to nylon. It is the most commonly used grade for gears, sheaves, sprockets and custom parts. It is grey-black in color. |

Nylatron® NSM Nylon
Best bearing and wear nylon product available today. Proprietary type 6 nylon formulation produced using Quadrant's Monocast® process. Solid lubricant additives impart self-lubricating, high pressure/velocity and superior wear resistance characteristics. Nylatron NSM was developed specifically for demanding applications where larger size parts are required. It is ideal for bearings, gears and wear pads.
In wear applications, Nylatron NSM lasts up to 10 times longer than standard Type 6 nylon. |
|
For best wear resistance and lowest coefficient of friction for tough industrial applications and where FDA compliance is necessary.

Nylatron® LIG
Nylatron® LIG combines the toughness of cast PA6 with an oil-based lubricant that is encapsulated within the nylon matrix. It increases the load beariang performance of the material when compared to unfilled nylons and reduces the coefficient of friction. It is an ideal material for industrial application.
Nylatron® LFG
Nylatron® LFG takes the performance of Nylatron® LIG and adds FDA compliance for appplications where food contact is possible. Food packaging and processing equipment users can now benefit from the benefits of this material. |
| For improved load capacity or For improved frictional characteristics |
30% Glass-reinforced Nylon 6/6
For applications requiring higher compressive strength and rigidity, 30% glass reinforced Nylon 6/6 is also available. It is stocked in diameters ranging from 10mm to 150mm (or .394" to 5.910" in meter lengths). |
Nylatron® GSM Blue Nylon
The first cast nylon to combine both molybdenum disulphid (MoS) and oil for the load capacity of Nylatron GSM nylon, plus improved frictional characteristics. It excels in higher pressures, and at low speeds-up to 40 fpm. It offers 20% lower coefficient of friction, 50% greater limiting PV, and a lower "k" factor than Nylatron GSM, and the lowest "slip-stick" of any nylon product making it ideal for slide pads, thrust washers and trunion bearings. Nylatron GSM Blue should be considered for any oil-filled nylon application. It is dark blue in color. |

Nylatron® 703XL
This ultra-high performance bearing grade of PA6 provides wear resistance near the levels of Nylatron NSM wtih superior load bearing capability and an industry first - a near zero level of "stick-slip." This elimination of chatter provides an extraordinary amount of control for high precision applications. |

Engineering Notes
Nylons can absorb up to 7% (by weight) water under high humidity or submerged in water. This can result in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor.
