Polyvinyl Chloride Resin (PVC Resin) CAS 9002-86-2

Polyvinyl chloride (PVC) is one of the world's largest-produced and most widely used general-purpose plastics. The suspension polymer SG-5 type is the most widely used and readily available grade in China. We also supply a full range of products including SG-3 (soft products), SG-7/8 (injection molded products), and paste resin (E-PVC). Our products are widely used in pipes and fittings, profiles and windows, wires and cables, films, artificial leather, flooring, packaging, and medical gloves. Our products strictly adhere to national standards such as GB/T 5761-2018. SG-5 is particularly well-stocked, and we support small-batch trial orders. With access to major northern ports such as Shandong and Tianjin, sea freight exports are efficient and convenient.

Product Information

ItemDescription
Product NamePolyvinyl Chloride Resin (PVC Resin)
CAS No.9002-86-2
AppearanceWhite powder (suspension grade); white granules (mass grade)
Production ProcessesCalcium Carbide Process: uses coal, limestone and salt as raw materials; accounts for approx. 72% of China's PVC capacity; cost-competitive.
Ethylene Process: uses petroleum ethylene as raw material; higher purity product; accounts for approx. 28% of China's PVC capacity; dominant process overseas.
Main Types (by Degree of Polymerization/K-Value)SG-3: DP approx. 1300, K-value 70-72. High molecular weight, high strength. For flexible products (wire/cable, hoses, film, artificial leather).
SG-5: DP approx. 1000-1100, K-value 66-68. Largest volume grade in China. For rigid products (pipes, profiles, windows).
SG-7: DP approx. 700-750, K-value 60-62. Good flowability. For injection molded products (pipe fittings, valves).
SG-8: DP approx. 650-700, K-value 58-60. High flowability. For complex injection parts, shoe materials.
Paste Resin (E-PVC) : Ultra-fine particles (0.1-2μm). For artificial leather, wallpaper, flooring, gloves.
Mass/Mass PVC: Pure polymerization system, excellent electrical properties. For transparent products, premium packaging, high-insulation applications.
Key Physical & Chemical PropertiesDensity: 1.35-1.45 g/cm³ (rigid ~1.38, flexible ~1.2-1.3); Glass Transition Temp: 77-90℃; Thermal Decomposition: starts at ~140℃ (releases HCl); Flame Retardancy: LOI 45%, self-extinguishing; Water Absorption: <0.5%; Electrical Insulation: volume resistivity 10¹⁵-10¹⁶Ω·cm.
Typical Performance ParametersK-Value: SG-3 70-72; SG-5 66-68; SG-7 60-62; SG-8 58-60.
Viscosity Number: SG-3 130-140 mL/g; SG-5 107-118 mL/g; SG-7 85-95 mL/g; SG-8 75-85 mL/g.
Volatiles: ≤0.3%-0.5%.
Apparent Density: 0.45-0.60 g/mL.
Residual VCM: ≤5 ppm (food grade ≤1 ppm).
Plasticizer Absorption: SG-3≥26 g/100g; SG-5≥20 g/100g; SG-7/8≥16-18 g/100g.
FeaturesSelf-extinguishing with excellent flame retardancy (LOI 45%, best among commodity plastics); excellent chemical resistance (acids, alkalis, salts, most organic solvents); excellent electrical insulation; rigid or flexible (adjustable via plasticizer content); good mechanical strength; good processability (extrusion, injection, calendering, blow molding, slush molding); cost-effective.
Main ApplicationsConstruction/Building Materials (>60%) : Pipes and fittings, profiles/windows, sheets/boards, flooring/wallpaper, waterproofing membranes.

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
