  • Why Add TPU to PVC? The Science and Benefits
    Why Add TPU to PVC? The Science and Benefits Aug 26 , 2026
    Polyvinyl chloride (PVC) has long been valued across industries for its cost‑effectiveness, flame retardancy, electrical insulation, and chemical resistance. However, virgin PVC suffers from inherent limitations: low impact strength, poor thermal stability during processing, and inadequate low‑temperature flexibility. To overcome these constraints, thermoplastic polyurethane (TPU) has emerged as o...
  • How to Select TPU for PVC Modification Aug 31 , 2026
    Successful PVC-TPU polymer-blend modification relies not only on material intrinsic compatibility (intermolecular hydrogen‑bonding between TPU urethane groups and PVC polar C‑Cl groups), but also on proper TPU grade selection and strict processing‑temperature control. PVC is a thermally‑sensitive polymer; its narrow safe‑processing window creates unique practical challenges for compounders. The gu...
