Intro<\/span><\/strong><\/span><\/p>\n

GOYENCHEM GGK-670<\/strong>\u00a0prevents the processing\u00a0light and weather induced degradation of polyurethane product.
\nGOYENCHEM GGK-670<\/strong>\u00a0is a\u00a0high potency type anti-uv and color stabilizer used in polyurethane .Especially suitable for polyurethane-foam\u3001paint\u3001leather\u3001TPU\u00a0<\/span>
\nGOYENCHEM GGK-670<\/strong> can make your\u00a0PU products meet the world standard of anti-yellow and UV light test.<\/span>
\nGOYENCHEM GGK-670<\/strong>\u00a0is used in\u00a0polyurethane. Especially suitable for thermoplastic polyurethane.<\/span>
\nGOYENCHEM GGK-670<\/strong>\u00a0prevents degradation of thermoplastic polyurethane from processing, light and weather, especially for discoloration from sunlight.\u00a0It does not affect initial color of TPU from synthesis process. Adding UV absorber into extruder from TPU synthesis process, the UVA have to drop into extruder between 2\/3 to 4\/5 of screw length.<\/span><\/p>\n
