Frequently Asked Questions

How do HDPE, LDPE and LLDPE differ for purchasing?

They differ in structure, density and processing behavior. Specify the product, process and required tests instead of requesting PE generically.

Can PE be selected only by MFI?

No. MFI must be reviewed with its test condition, density, process and end-use performance.
