Drying Check — Polyolefins (PP/PE)
Whether Polyolefins (PP/PE) needs drying, and the energy cost of unnecessary drying.
PP and PE are non-hygroscopic — surface condensation from a cold warehouse is the only 'moisture' they carry, cured by an hour of warm air, not a desiccant cycle. Drying them at 80 °C for 4 hours is pure energy waste, and this calculator prices exactly that habit.
Formula
Note: Starting-point process values — the resin grade's datasheet and an in-mold study govern. Verify with a gate-seal study and a cooling-time ladder on the actual tool.

About Drying Check — Polyolefins (PP/PE)
Drying Check — Polyolefins (PP/PE) computes the governing relationship waste = kg/h × kWh/kg × h × $/kWh live as you type. PP and PE are non-hygroscopic — surface condensation from a cold warehouse is the only 'moisture' they carry, cured by an hour of warm air, not a desiccant cycle. Drying them at 80 °C for 4 hours is pure energy waste, and this calculator prices exactly that habit. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Drying Check — Polyolefins (PP/PE)
- 1Enter your values — Throughput, Dryer energy, Running hours/yr, Electricity (sensible defaults are pre-filled).
- 2Read the live results: Cost of unnecessary drying.
- 3Check the "with your numbers" line to see waste = kg/h × kWh/kg × h × $/kWh substituted step by step.
