Polímeros
Os polímeros são macromoléculas formadas pela repetição de unidades menores chamadas monômeros, unidas por ligações covalentes. Esses materiais possuem uma variedade de propriedades físicas e químicas que os tornam essenciais em uma ampla gama de aplicações industriais e científicas, incluindo a fabricação de plásticos, fibras, elastômeros, adesivos e revestimentos. Na CymitQuimica, oferecemos uma ampla gama de polímeros de alta qualidade e pureza, projetados para atender às necessidades específicas de sua pesquisa e desenvolvimento, bem como às demandas da produção industrial. Nosso catálogo inclui polímeros com várias características adequadas para usos em biomedicina, engenharia, eletrônica e muito mais.
