EPP, EPS, PU, EPO, TPU — Which Foam Mould Should You Actually Quote?

Nantong, Jiangsu — August 28, 2026 — Procurement teams sourcing foam-mould tooling from China often receive quotes in multiple resin families without fully understanding the trade-offs. A new specification-comparison guide from Nantong Bainuo Mould Co., Ltd. tries to fix that by walking buyers through the five most common foam families before they send an RFQ.

The guide breaks each material down by density range, energy absorption, heat tolerance, recyclability, mould-steel requirements and typical cycle time. The short version: EPP is the workhorse for automotive energy management, EPS is cheaper for one-trip protective packaging, PU delivers comfort and recovery for seat applications, EPO sits in the middle for industrial dunnage, and TPU brings abrasion resistance where it is needed.

"Most RFQs that arrive in our inbox are mis-specified," a Bainuo engineer said. "Buyers ask for an EPP mould when their product really wants an EPO or PU mould. Once we talk it through, they end up with a better part at a lower tool cost."

The comparison table is being picked up by sourcing teams in Europe, the Middle East and Southeast Asia as a quick desk reference when triaging new foam-tooling projects.
