Polímeros
Los polímeros son macromoléculas formadas por la repetición de unidades más pequeñas llamadas monómeros, unidas mediante enlaces covalentes. Estos materiales poseen una variedad de propiedades físicas y químicas que los hacen esenciales en una amplia gama de aplicaciones industriales y científicas, incluyendo la fabricación de plásticos, fibras, elastómeros, adhesivos y recubrimientos. En CymitQuimica, ofrecemos una extensa gama de polímeros de alta calidad y pureza, diseñados para satisfacer las necesidades específicas de su investigación y desarrollo, así como las demandas de producción industrial. Nuestro catálogo incluye polímeros con diversas características, adecuados para usos en biomedicina, ingeniería, electrónica y más.
