The choice depends on the load, temperature, environment, service life, and manufacturing route. Choose silicone for temperature extremes, UV exposure, and long-term sealing. Choose polyurethane for abrasion, load-bearing, impact, and broad hardness options. That simple rule prevents many early mistakes. It is not enough for a final material specification. A wheel, static gasket, medical valve, potting compound, and construction sealant may all use one of these polymers, but they do not ask the material to do the same job.
