application                                        UV 5050 H can be used in all polyolefins. 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
