application UV 5050 H can
be used in all
polyolefins. It is
particularly suitable for water-cooled tape production, films
containing PPA and TiO
2 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
