Not all polyethylene is created equal — especially when it comes to rotational molding.
LLDPE vs. HDPE. Melt index. UV stability. Pigments. Reprocessed material. Molded features. Long-term outdoor performance.
Choosing the right resin can have a huge impact on how a rotationally molded product performs, processes and holds up over time.
We put together a detailed guide covering some of the biggest factors that go into polyethylene selection for rotational molding — including the kind of real-world lessons that only come from actually making parts.
If you design, source or manufacture plastic products, this one is worth a look.
