Plain-English comparisons for choosing the right plastic, with links to who stocks and machines each one.
PEEK vs UltemHeat, chemical resistance, strength and cost compared, and when each one is worth it.UHMW vs HDPESame family, very different jobs: wear, impact, welding and cost compared.Delrin vs UHMWPrecision vs toughness: friction, tolerances, impact and cost for wear parts.Delrin vs acetalHomopolymer vs copolymer, Delrin 150 and AF, porosity and when it matters.Delrin vs nylonMoisture, tolerances, wear and load for bushings, gears and rollers.Torlon vs PEEK vs VespelThe top of the pyramid: temperature, strength, wear and cost compared.Nylon 6 vs nylon 6/6PA6 vs PA66, cast vs extruded nylon, and where nylon 12 fits.FDA plastics for food contactWhat FDA compliance really means, common food-grade plastics and what to ask for.Low-friction plastics for wear stripsUHMW, PTFE, acetal, filled nylon and PEEK for sliding and wear.G10 vs FR-4Glass-epoxy laminates compared, plus where G11 and phenolics fit.Polycarbonate vs acrylicImpact vs clarity: guards, windows, displays and signs compared.High-temperature plastics chartTypical continuous service temps from HDPE to Vespel, and how to pick for heat.Chemical-resistant plastics chartPTFE, PVDF, PP, PVC, PEEK and more rated against acids, bases, solvents and steam.PVDF vs PTFEKynar vs Teflon: strength, weldability, chemicals, heat and PFAS questions.
