Melt tempreture
(OP)
Does anyone knows what is the minimum and maximum melt temperature for EP332L Polyproplene.
I need the melt temperature in order to figure/determine the holding pressure graph i.e process window.
Thanks
Clifton

Thanks for your reply... I have the following article but unfortunatley i had no luck....

Mainly the melt temperature should be around 230 deg celcius.
But in order to do the holding pressure graph i.e process window i need the minimum/maximum.
Thanks

From the link above - Table on page 15
Flow Characteristics Melt Temperature
Range, °F (°C)
Low flows 475-500 (246-260)
Medium flows 445-475 (228-246)
High flows 400-445 (200-228)
Extra high flows 385-420 (200-215)
Ultra high flows 370-385 (185-190)

We can give general replies, but t answer accurately, we would need to determine who the manufacturer is then contact them or we would need to go to matweb for you. You can just as easily do it for yourself.

With an MFI of 7, I would put it in the medium class - 228 to 246C.
