Additionally, there are many specialty grades formulated to fit particular processes.
Processing most grades of SEBS or SEPS TPEs over 460°F can cause them to degrade as indicated by a burnt odor.
Your GLS sales engineer can help you determine the best choice of grades for individual applications.

Moving away from virgin resin to using the same grade of PCR, you can expect both processing conditions and product performance to change.
Organoleptic performance is an important concern because most PCR grades are not degassed and can contribute offensive odors to the parts
Choose a quality grade of PCR with fewer odor profiles

Barrel Capacity
If possible, use a machine that utilizes 25% to 75% of the barrel shot size capacity.
The feed zone temperatures should be set fairly low [typically 250°F–
300°F (120°C–150°C)] to avoid feed-throat bridging and allow entrapped air to escape.
Harder grades (>50 Shore A) will set up faster in the mold compared to very soft grades
