Thermylene® TPO Grades

Thermylene® 's TPO grades are specialty compounded products available in various reinforcements and stiffness-toughness performance spectrums. They deliver critical attributes necessary for interior as well as exterior applications like high ductility performance at cold temperatures, high flow for thin-wall molding, excellent scratch resistance, acceptable gloss and aesthetics, and superior weathering resistance.

Thermylene® Glass Filled Grades

Glass fiber (GF) is the most widely used reinforcement in polypropylene (PP)-based composites as it provides a valuable balance between costs and properties. Glass-fiber-reinforced polypropylene compounds (PPGF Plastic) deliver improved strength, structural rigidity and dimensional stability in applications.

The key performance in glass-reinforced polypropylene compounds is delivered by the efficacy of formulation design and polymer fiber interphase. Thermylene® products provide increased durability, strength and stiffness for critical structural components. Polypropylene compounds that are long glass fiber reinforced have significantly improved flexural modulus and tensile strength because of superior design and state-of-the-art production technologies applied by Asahi Kasei.
