Nylon PA Polyamide
DESCRIPTION
Nylon is a common synthetic plastic material composed of polyamides of high molecular weight. It was developed in the 1930s by a research team working for E.I. du Pont de Nemours & Company. Nylon is a versatile material used in everything from stockings and toothbrush bristles to industrial wear components such as bushings, bearings, and gears. One of the first successful commercial plastics, development was directed to wartime purposes during WWII in the form of parachutes and tents. Today it is still heavily used in the fabric industry with many high-performance applications like extreme outer clothing, and ballistic nylon for luggage, back packs, belts, and many more.
Nylon is known as the workhorse of the industry due to its toughness. Nylon can be processed in different ways, injection molded, extruded or cast. Nylon is naturally FDA, USDA and dairy compliant. Nylon lends itself to additives to enhance its physical properties. Common fillers used in Nylon are glass fibers, oil and molybdenum disulfide (MD). Reach out to Meyer Plastics, our inventory is full of Nylon in various stock shapes. We will also cut-to-size stock sheet, rod or tube to the dimension you require, which means we have a large inventory of cutoffs readily identified in our inventory. Maybe you need a fabricated or machined part, we can do that too. Not to be out done, we even can 3D print your design from a selection of Nylon resins including, with carbon fiber. At Meyer Plastics we can be your partner for successful project sourcing.

Nylon 12
Nylon 12 is comparable to nylon 6 with higher tensile elongation and impact strength than standard cast nylon. It has superior dimensional stability and lower water absorption, making it an ideal choice in a variety of harsh environments. that require an extra degree of toughness, like ball valve seats in the oil & gas industry.

Nylon MD (Nylatron MD®)
Nylon 6 material with the additive molybdenum disulfide (MoS2), creates a higher crystalline product with improved mechanical properties and built-in lubrication. Cast Nylon brands this product NYCAST 6PA MoS2 and it delivers improved wear resistance and compressive strength over the standard grade 6PA, while also adding dry lubrication benefits. Nylatron MD is the most common brand known and used in the industry and owned by Quadrant. Nylon MD is typically black.

Nylon 6
Typical Properties of Nylon 12
Nylon 66
Nylon 66 is similar to nylon 6 however has higher temperature service, stronger tensile, and better resistance to water absorption. When molding into shapes it does however have greater shrinkage so less accuracy in the molded shape. Nylon 66 will be more expensive than nylon 6.
