About A-Line Products

A-Line Products, founded in 1965 and based in Detroit, Michigan, specializes in polymer additives and chemical intermediates. Their product range includes liquid rubber cutbacks made from synthetic rubbers such as butyl, polyisobutylene (PIB), EPDM, and SBS, which enhance toughness and flexibility in polymer systems. They also offer waterborne chlorinated polyolefin adhesion promoters designed to improve bonding on polypropylene (PP) and thermoplastic polyolefin (TPO) substrates commonly used in automotive and industrial applications. Additionally, A-Line produces natural oil polyols that serve as functional intermediates in polymer formulations. These products help formulators improve mechanical performance, interfacial adhesion, and flexibility, mainly in thermoplastics and elastomers.
