Specialty Grades
For heat and outdoor service: M640A with a higher melting point, M630V UV-stabilised for weathering.
01 Material Overview
The specialty series addresses two extreme requirements. M640A raises the melting point by adjusting the copolymer composition, making it suitable for structural parts that work long-term at elevated temperatures, for example components near the engine bay or inside luminaires.
M630V carries a UV stabiliser system for articles exposed outdoors over the long term, such as automotive exterior trim, outdoor equipment housings and garden machinery parts. Unstabilised POK chalks and discolours on the surface under strong UV; M630V significantly slows that process.
Where flame retardancy or reinforcement is also needed, pick the corresponding system from the modified range, or contact us about a combined formulation development.
