They had different requirements: some needed to increase flow to aid cavity fill, some needed help with release, some needed help with consistency others needed to improve start up and some needed to reduce processing temperatures because of degradation of the polymer.
According to Genie Kenraw just 0.2-0.3 per cent addition of INT-35UDH resolved all these problems. Average processing temperatures are down to 260 -265 degC from 280-300 degC. They have also seen an …
