The two-step extrusion method was used to manufacture pipe-grade high density polyethylene (HDPE) material from recycled HDPE. With the two-step extrusion method, dicumyl peroxide (DCP) can completely ...

Chemists can demonstrate how to make high-density polyethylene with better control over polymer chain lengths, which allows for improvement over physical properties such as processability and strength ...

Trials with several pipe producers have shown that the use of an extrusion line designed for the Spherisil process provides processors with the flexibility to run crosslinked and thermoplastic pipes ...

targets tough, stiff, high-clarity films, with processing possible on both linear low-density polyethylene (LLDPE) and low-density polyethylene (LDPE) film-line equipment. Processing and shrink ...

TORONTO (Oct. 10, 9:30 a.m. ET) — For the second straight year, post-consumer high density polyethylene recycling has remained stagnant. The North American recycling rate for HDPE remained at 29.9 ...
