Request Information
Cast Nylons are a range of polyamides produced by a casting process involving the anionic polymerisation of caprolactum. This process allows the production of semi-finished plate, rod, tube and custom castings that are largely free of internal stresses. Natural Cast Nylon is the basic grade from which all other grades of Cast Nylons stem. Generally accepted as the primary engineering polymer, Natural Cast Nylon is suitable for virtually any plain bearing application not to mention a huge range of other applications for which this versatile grade finds a use. By varying the conditions of polymerisation the mechanical properties of Cast Nylon may be altered to suit specific applications and the addition of various additives, fillers, lubricants and colorants.

N/A Cast Nylon/Type 6 (Nylon 6)
This unmodified Type 6 Nylon offers the highest strength and hardness of the Cast Nylon grades. Natural, Black, Blue and custom colors also available Meets or exceeds ASTM D5989 S-PA0211. LP-410A

Blue Cast Nylon/Type 6 - Heat Stabilized
Meets or exceeds ASTM D5989 S-PA0231.

Cast Nylon MD/Type 6 - Wear Resistant (MoS2 Filled)
This "Filled" Cast Nylon 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 Gray - Black in color. Meets or exceeds ASTM D5989 S-PA0221. LP-410A Wear Resistant

Cast Nylon MD+Oil/Type 6 (Oil-Impregnated - MoS2 Filled)
This grade combines Molybdenum Disulphide and Oil for the load capacity, plus improved frictional characteristics. It excels in higher pressures, and at low speeds-up to 40 fpm. It offers 20% lower coeficient of friction, 50% greater limiting PV, and a lower "k" factor than Cast Nylon MD, and the lowest "slip-stick" of any Nylon product making it ideal for slide pads, thrust washers and trunion bearings. Cast Nylon MD+Oil is available in Dark Blue & Gray.

Oil-Impregnated CAST NYLON - GREEN/TYPE 6
Meets or exceeds ASTM D5989 S-PA0251.
