‌Key Features & Advantages‌

1. ‌Superior Processability‌

   • ‌Optimized K-Value (57-60):‌ The resin's carefully controlled K-value ensures excellent melt flow characteristics, enabling smooth processing across a wide range of temperatures and machinery.
   • ‌Uniform Particle Size:‌ Narrow particle size distribution minimizes porosity and enhances fusion properties, reducing processing time and energy consumption.
   • ‌Low Volatile Content:‌ ≤0.3% volatile matter ensures minimal foaming and surface defects during high-temperature processing.

2. ‌Exceptional Mechanical Properties‌

   • High tensile strength, impact resistance, and dimensional stability make SG-5 resin suitable for rigid applications such as pipes, window profiles, and siding.
   • Excellent compatibility with plasticizers (e.g., DOP, DINP) allows for customization of flexibility in soft PVC products like cables, flooring, and medical tubing.

3. ‌Thermal & Chemical Resistance‌

   • Withstands temperatures up to 85°C (185°F) without deformation, ensuring longevity in outdoor and high-stress environments.
   • Resistant to acids, alkalis, and UV radiation, making it ideal for industrial and construction applications.

4. ‌Eco-Friendly & Compliant‌

   • Free from heavy metals (lead, cadmium) and compliant with REACH, RoHS, and FDA (for specific grades) regulations.
   • Low VOC emissions align with green manufacturing initiatives.

‌Applications‌

Ruiheng PVC Resin SG-5 is versatile across industries, including:

‌1. Construction & Infrastructure‌
