The EPDM granules are manufactured with stringent quality control right from the beginning to meet specific parameters such as its physical properties, weather resistance, UV stability and filing density. All products are sampled, retained and evaluated to ensure product quality consistency and conformance to specifications. Colored EPDM granules have different color stabilities and varying sensitivities towards the yellowing of PU binders, hence it is important that we educate our clients on their best fit.
