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...
