Affinity Chemical LLC manufactures and supplies aluminum sulfate (alum) and other specialty chemicals such as ferrous sulfate. But we’re not your typical chemicals vendor. We founded Affinity after long careers in the liquid aluminum sulfate industry. Time and again, we saw first-hand where regional markets were under-served, resulting in higher prices or price instability, and gaps in service. This experience led us to start a company with a different set of values. Affinity was born and continues to grow on one founding principle: understand the customers’ needs and deliver solutions to them through effective partnerships. When you work with Affinity Chemical, you’ll discover we serve you from a different dynamic. We’re entrepreneurs who collaborate with our customers and supply chain partners on building regional infrastructure to give you consistent alum product along with exemplary service and transparent, predictable pricing. Our customers range from Fortune 500 companies to small proprietors and all are treated with the respect and focus they deserve. We start by listening to customer needs, then we analyze the regional alum market, and collaborate with the customer and our supply chain partners to develop a solution that provides price security, high quality product, and dependable service.
