Nylon 6 — This material has excellent tensile and impact strength, chemical resistance and stiffness. In comparison to polyethylene, nylon is easier to paint and has improved abrasion resistance, wear resistance and creep resistance. The plastic is able to maintain its properties at elevated temperatures because it has high heat resistance. Applications include military fuel tanks, hydraulic oil and solvent tanks, grain buckets and air ducts.

Nylon 12 — Its moisture absorption, melting point and mechanical properties are lower than Nylon 6, but it is more easily processed. Applications include heating and air conditioning ducts, gasoline /diesel tanks and chemical tanks.
