PVC injection molding-grade granules are PVC compounds specially developed for injection molding processes. Based on PVC resin, these materials are modified with different additives to meet specific performance requirements for injection molded PVC products, including flexibility, strength, durability, and appearance.
Typical formulation characteristics of PVC injection molding-grade granules include:
Depending on the formulation, PVC injection molding-grade granules can be produced as flexible or rigid compounds. Flexible grades are mainly used for electrical plugs, toys, and floor mats, while rigid grades are suitable for PVC pipe fittings, junction boxes, and industrial components. Due to PVC’s narrow processing temperature range and sensitivity to thermal degradation, strict control of melt temperature and proper runner design are required during injection molding to ensure stable production and consistent product quality.
