PVC HARDNESS‑TUNING MODIFICATION

PVC hardness‑tuning modification realizes wide‑range hardness adjustment from ultra‑soft to semi‑rigid grades by precisely selecting and dosing plasticizers. It addresses the temperature‑sensitivity drawback of conventional soft PVC, which tends to turn overly soft in summer and brittle‑hard in winter. Specially formulated soft PVC greatly reduces temperature‑dependent property drift and delivers improved elasticity. Its hardness variation is kept within a reasonable range across ‑20 ℃ to 50 ℃.

Main Uses

Widely deployed in automotive, electrical and building‑material industries for articles requiring high flexibility, such as automotive sealing strips, electrical‑equipment cushioning pads and soft pipes.

Features: Hardness‑tuning Modification  

Physical Properties: Customized per user requirements (partial properties can match imported brands) Minimum order quantity: 1 ton upon successful sample testing
