Engineering Plastics — Machining, Properties & Material Selection
ASA vs ABS: Material Properties, UV Resistance, and When to Use Each ASA and ABS share a similar backbone chemistry and nearly identical processing behavior, but one critical difference separates them: UV and weathering resistance. Choose ABS for indoor applications, consumer electronics, and structural prototypes where cost efficiency and initial impact strength are paramount. Choose […]
Laser Engraving ABS Plastic: Material Properties, Optimal Settings, and Trade-Offs ABS is a versatile engineering plastic for laser engraving it produces clean, contrast-rich marks with minimal residue compared to cutting the same material. However, ABS has specific engraving requirements: incorrect settings cause charring, surface stress cracking, or toxic fume output. This guide covers the material
3D Printing ABS for Prototyping: When to Move to Injection Molding or CNC FDM-printed ABS is not the same material as CNC-machined or injection-molded ABS, same resin, different mechanical behavior. If your prototype needs to validate more than fit and form printing it can quietly mislead you. This guide breaks down exactly where FDM ABS
Flame Retardant ABS: Properties, UL94 Ratings, and Trade-Offs Engineers Need to Know Standard ABS does not meet UL94 vertical burn requirements without a flame retardant (FR) additive package. If your part sits near a heat source, live electronics, or falls under a safety standard requiring a UL94 rating, you need FR ABS but the additive

Delrin vs. Acetal: The Engineer’s Guide to Choosing the Right POM Delrin and Acetal are often treated as the same plastic, but they are not identical materials. Delrin is an acetal homopolymer (POM-H), while most materials sold as Acetal are copolymers (POM-C). This small molecular difference changes strength, chemical resistance, machining behavior, and reliability in
