PVC Ningbo Hanwha HG‑1300
PVC Ningbo Hanwha HG‑1300 Resin
Material Introduction: PVC Ningbo Hanwha HG‑1300 is a high‑molecular‑weight general‑purpose suspension‑polymerized PVC resin. Benefiting from balanced processing performance, good mechanical‑strength potential and high plasticizer‑absorbing capacity, it is applicable for rigid‑grade products, and soft‑grade articles can also be manufactured by formula adjustment.
Main Applications
Rigid‑grade Products (U‑PVC): With low plasticizer dosage in formula, HG‑1300 can be used for pipes, pipe fittings, door‑window profiles and other products requiring certain strength and stiffness.
Soft‑grade Products (P‑PVC): Taking advantage of its high plasticizer‑absorbing capacity, after adding proper plasticizer, HG‑1300 can produce soft sheets, hoses, cable sheaths, soft films and other flexible‑required articles.
