Nylon 11 or Polyamide 11 (PA 11) is a polyamide, bioplastic and a member of the nylon family of polymers produced by the polymerization of 11-aminoundecanoic acid. It is produced from castor beans by Arkema under the trade name Rilsan .
Float-equipped PA-11S at Seattle Renton in 1973. A small number of PA-11s have been modified to use a Tricycle landing gear. [3] The PA-11 was one of the first aircraft to be used by Piper for experiments with the nose wheel (also known as tricycle gear) configuration. Although its original design is intended to be a tail-dragger, a ...
Repeating unit of polyphthalamide. Polyphthalamide (aka.PPA, [1] High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids. [2]
Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of PEBAX® and VESTAMID® E (Evonik Industries).It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG).
Synthetic polyamides are commonly used in textiles, automotive industry, carpets, kitchen utensils and sportswear due to their high durability and strength. The transportation manufacturing industry is the major consumer, accounting for 35% of polyamide (PA) consumption. [2]

One number after "PA" or "Nylon" indicates a homopolymer which is monadic or based on one amino acid (minus H 2 O) as monomer: PA 6 or Nylon 6: [NH−(CH 2) 5 −CO] n made from ε-caprolactam. Two numbers or sets of letters indicate a dyadic homopolymer formed from two monomers: one diamine and one dicarboxylic acid. The first number indicates ...
