HDPE vs PP: When Should You Use Which?

HDPE and PP are both common, but each suits different applications.

Key Points

• HDPE offers good impact resistance and is widely used for bottles and jerrycans.
• PP tolerates higher temperatures and is often chosen for caps and technical parts.
• PP is generally stiffer, while HDPE is more flexible at low temperatures.

Matching the polymer to the use case helps avoid rework later.
