Engineering Plastics Material Database
Compare mechanical, thermal, and chemical properties across 50+ engineering plastics — ABS, Nylon, Polycarbonate, PEEK, Acetal, and more. Find the right plastic material for CNC machining, injection molding, or 3D printing.
Why This Material Database Matters
Choosing the right engineering plastic directly affects part performance, manufacturing cost, and lead time. A material that works perfectly for injection molding may fail in CNC machining due to stress cracking or heat buildup. This database gives you real, comparable property data — not marketing claims — so you can make data-driven decisions.
Each material entry includes tensile strength, flexural modulus, heat deflection temperature, impact resistance, and density — the five properties most engineers check first. Use the search and filter tools below to narrow down candidates for your specific application.

How to Choose the Right Engineering Plastic
Material selection isn't about finding the "best" plastic — it's about finding the one that meets ALL your requirements at the right cost. Here's the decision framework we use with customers at Nylon Plastic.
1. Temperature Requirements
Check both continuous use temperature and peak exposure. If your part sees >150°C, narrow to Nylon 6/6, PEEK, PEI, or PPS. For <100°C, ABS and PP are cost-effective choices.
2. Mechanical Load
Structural parts need high tensile strength and flexural modulus. Glass-filled grades (30% GF) can double or triple stiffness. Nylon 6/6 GF30, PEEK GF30, and PPS GF40 are top picks.
3. Chemical Exposure
For harsh chemicals, fluoropolymers (PTFE, PVDF) offer the best resistance. PPS and PEEK handle most industrial solvents. Avoid nylons in high-moisture or acidic environments.
4. Manufacturing Process
CNC machining suits low-volume, tight-tolerance parts. Injection molding wins for high volume. Some materials are process-specific — PTFE and UHMWPE are CNC-only, while LCP requires injection molding.
5. Cost vs Performance
PP and ABS cost $2-5/kg. Nylon 6/6 is $4-8/kg. PEEK jumps to $80-120/kg. Ask yourself: do you really need PEEK, or would a glass-filled nylon handle the job at 1/15 the material cost?
6. Certifications & Compliance
Medical devices may need ISO 10993 or USP Class VI. Food contact requires FDA compliance. Aerospace often demands FST (flame/smoke/toxicity) ratings. PEI, PEEK, and PPSU are common medical/aerospace choices.
