Specialty UV stabilizer masterbatches that protect polyolefin products from sunlight-induced degradation — widely used in FIBC, woven sacks, tape, fiber and film.
K1560® is a specialty UV stabilizer concentrate containing 25% UV stabilizer based in polypropylene. This concentrate is designed to offer UV protection by quenching oxidative byproducts resulting from the exposure to UV light. K1560® has a minimal effect on the color or melt index of products to which it is added.
▪ Bulk bag / plastic flexible container bags / flexible intermediate bulk container.
▪ Plastic woven sack / wool pack.
▪ Awning, mesh (vegetable) bags, film, fiber.
▪ Injection and blow molding.
K1560® is recommended for use at 0.6% to 2% addition levels depending upon customer specific application requirements. At 1.0% addition level, FIBC fabrics with K1560® will meet requirements of both ISO 21898 (the FIBC international standard) and ASTM G154 (Standard Practice for UV exposure of nonmetallic materials).
Expose test samples to fluorescent UV-B light in QUV Accelerated Weathering Tester for at least 200 hours, using a test cycle of 8 hours at 60 °C with UV radiation, alternating with 4 hours at 50 °C with condensation.
Use within 24 months of production date for optimum performance.
In accordance with good industrial practices, handle with care.
