Zytel® LCPA

A flexible polymer that combines heat, chemical, and hydrolysis resistance in a range of grades.

Car going down the road.

Zytel® LCPA flexible polymer materials provide an innovative and growing portfolio of long-chain polyamides with excellent thermal, chemical, and hydrolysis resistance.

The various grades of Zytel® LCPA are designed to meet specific performance needs, including everything from high temperature resistance and stiffness to lower fuel and gas permeability. 

This important product family continues to expand. With science-driven innovation, we have chemically modified PA610 and PA612 products, adding two new polymer series to the Zytel® LCPA portfolio. Zytel® RSLC 4000 and Zytel® LC 7000 offer a step change improvement over existing grades; both products meet customer needs for salt resistance and increased flexibility.   

The expanded portfolio provides increased resistance to chemicals and cracking, excellent yield and stiffness balance, and blow-molding compatibility.

The Zytel® LCPA line also includes one of the industry’s widest arrays of innovative, renewably sourced (RS) materials. The RSLC grades are partially or entirely derived from non-food biomass. They provide performance properties that enable companies to reduce the use of fossil fuels in polymer feedstock, even in demanding applications.
