It is mainly polymerized with bio-based pentylenediamine and petroleum-based adipic acid, and the bio-based content is as high as 47%-100% or more.

wherein PA510 is obtained by polymerizing sebacic acid (biobased sebacic acid) from castor oil plants and pentamethylene diamine (biobased 1,5-pentanediamine) from corn.Bio-based content up to 100%。
