White HPDE going brown

Hello community

we’re in the early stages of developing our plastic products using some of the machines and have run into a problem using white hdpe. whenever we melt it its starts to turn brown after about 10 minutes under heat.

any pointers?

cheers

Sounds like it’s burning? Maybe try a lower temperature for a bit longer

yeah thought that might be there case. Thanks for the tip
