PEN Granules

PEN Granules are part of our extensive range of engineering materials. With 13 size variations available, this additive-free polymer made of polyethylene naphthalate (PEN) is valued for properties like high strength, stiffness and temperature resistance. Applications for these granules include thin films, composites, and high-performance fibers where properties like dimensional stability and low permeability are needed. The availability of polyethylene naphthalate in a granular form allows flexibility across processing methods.
