Nylon 6/6-PA (Polyamide)

Nylons are semi-crystalline polymers with a good range of properties. Nylons are widely used because they have a good cost to performance ratio. Lower numbered nylons, 6 ,6-6, 4-6, absorb moisture and change their properties as a result. Nylons have been compounded with reinforcements, fillers and additives to produce a very wide variety of properties. Nylon 6-6 offers better properties than nylon 6 without being as costly as nylon 4-6. It has the best abrasion resistance of all nylons. Verton, long glass fiber filled materials, by LNP, are excellent metal replacement materials.

Applications: Automotive components, electronic connectors, gears, consumer products and industrial products.

Brand Names: Adell, HiFill, Ultramid, Zytel.
