Crafted through East Hope’s proprietary polymerization technology, SG-5 resin features a uniform particle size distribution, minimal residual vinyl chloride monomer (VCM <1 ppm), and enhanced compatibility with additives. Whether extruding pressure-resistant pipes for construction, calendaring transparent films for packaging, or molding precision components for automotive systems, SG-5 delivers consistent results across diverse processing methods. Backed by rigorous quality control and decades of expertise in polymer innovation, East Hope PVC Resin SG-5 is the trusted choice for manufacturers prioritizing performance, sustainability, and cost efficiency.

‌Key Features & Advantages‌

1. ‌Unrivaled Purity & Consistency‌

   • ‌Ultra-Low Impurities:‌ Residual VCM ≤1 ppm and ash content ≤0.05% ensure compliance with FDA, EU, and other food-contact regulations (specific grades available).
   • ‌Uniform Particle Size (100–150 μm):‌ Enhances flowability, reduces porosity, and accelerates gelation for faster processing cycles.
   • ‌High Bulk Density (0.55–0.60 g/cm³):‌ Minimizes storage and transportation costs while improving handling efficiency.

2. ‌Superior Processing Performance‌

   • ‌Optimized K-Value (66–68):‌ Ideal balance of melt viscosity and mechanical strength for extrusion, injection molding, and calendaring.
   • ‌Excellent Thermal Stability:‌ Withstands processing temperatures up to 210°C without degradation, reducing scorching risks during high-speed extrusion.
   • ‌Low Volatile Content (≤0.3%):‌ Prevents foaming and surface defects in finished products.

3. ‌Enhanced Mechanical & Functional Properties‌

   • ‌High Tensile Strength & Impact Resistance:‌ Ideal for rigid applications like potable water pipes, industrial conduits, and window profiles.
   • ‌Flexibility Customization:‌ Compatible with a wide range of plasticizers (e.g., DINP, DOTP) for soft PVC films, cables, and medical tubing.
   • ‌Chemical & UV Resistance:‌ Withstands acids, alkalis, and prolonged outdoor exposure, making it suitable for agricultural films and corrosive environments.

4. ‌Sustainability & Compliance‌

   • ‌Eco-Friendly Formulation:‌ Free from heavy metals (lead, cadmium) and compliant with REACH, RoHS, and NSF/ANSI 61 standards.
   • ‌Low Carbon Footprint:‌ East Hope’s energy-efficient production process reduces CO₂ emissions by 20% compared to industry averages.
