It is particularly suitable for water-cooled tape production, films containing PPA and TiO2 and agricultural applications. It can also be used in PVC, PA and TPU as well as in ABS and PET.processing UV 5050 H is supplied in pellet form. In order to achieve a homogenous distribution it is necessary to follow this temperature program in batch production: PP PE (HD and LD) feeding zone < 50 °C < 50 °C < (122 °F) < (122 °F)heating zone 1 80 °C 80 °C (176 °F) (176 °F)kneading zone 200-240 °C 180-220 °C (392-464 °F) (356-428 °F)This temperature program yields best homogenization at high throughput
