Greengran B621J (heavy weight waterworks grade)

Greengran B621J (Heavy Weight Waterworks Grade) is a standard waterworks grade. Granules based on polypropylene and natural fibers, which combines very high stiffness and strength with moderate impact strength. Its excellent heavy weight outdoors properties and moisture stability make it suitable for sweat- and salt water use. Typical markets are within shoreline protection- and artificial reef applications.
