Selection Decision Tree
· Temperature requirement?→ PEEK or PTFE > 200°C
· Need structural strength?–→ PEEK
· Need chemical inertness? → PTFE
· Need chemical resistance? → PPS
· Need flame retardancy? → PEI
· ─ 80–150°C → PA66 or POM
· Need impact strength? → PA66
· Need dimensional stability? → POM
· ESD protection needed? → ESD POM
· < 80°C → Commodity plastics (not NAGOMER focus)

FAQ
Q1: Which engineering plastic has the highest temperature resistance?
PEEK (250°C continuous) and PTFE (260°C continuous) offer the highest temperature resistance among commonly available engineering plastics. For extreme temperatures above 260°C, specialty materials like PAI (Aramid) or PBI can be used but at significantly higher cost.
Q2: What is the most cost-effective engineering plastic?
POM (polyoxymethylene) is the most cost-effective engineering plastic for the majority of industrial applications. At $4–8/kg, it offers excellent mechanical properties, machinability, and wear resistance at a fraction of the cost of high-performance plastics like PEEK.
Q3: Which engineering plastic is best for semiconductor applications?
PEEK is the premium choice for semiconductor components due to its purity, high temperature resistance, and mechanical strength. ESD POM is the cost-effective alternative for wafer handling components where temperature is not a concern. The choice depends on the specific process requirements.
Q4: Can engineering plastics replace metal?
Yes, engineering plastics can replace metal in many applications, offering 50–70% weight reduction, corrosion resistance, and design flexibility. PEEK and PEI can replace aluminium in structural components, while POM replaces brass/bronze in wear applications. Material substitution requires careful engineering analysis.
