Only the required quantities of masterbatches and base resins need to be stored which reduces the risk of slow-moving stocks. Since maintaining a good melt flow can sometimes be challenging with effect pigments, our team of material experts from Avient Design can provide support to reduce new product design errors by linking design with manufacturability and to speed up the design process. Using recycled materials is one way to attract eco-conscious consumers, but also to prepare for possible future legislation as governing bodies are looking to reduce carbon emissions.
