Description

Bastone is proud to supply PVC S-1300, a high-quality suspension polyvinyl chloride resin manufactured by SINOPEC, one of the world's leading petrochemical companies. As a trusted supplier, we provide this premium-grade material with flexible ordering options and comprehensive customer support.

The S-1300 grade offers the optimal balance of processing performance and end-product quality. With a higher degree of polymerization (1250-1350) compared to S-1000 or S-700 grades, S-1300 provides superior mechanical strength and better impact resistance in finished products. The higher molecular weight delivers improved melt strength and better formability, particularly beneficial for extrusion and calendaring processes.

Our S-1300 meets stringent quality standards (O/SH3055.77-2007) with both Superior and Qualified grades available. The resin features an apparent density of 0.45-0.52 g/mL and volatile matter content kept at ≤0.20% for Superior grade. Residual VCM is strictly controlled at ≤2.0 μg/g for Superior grade and ≤5.0 μg/g for Qualified grade, ensuring safety and quality.

We understand that flexibility is key to your business. Our lower MOQ requirements make it easier for you to order the quantities you need without excessive inventory burden. Our experienced technical and customer service team provides comprehensive support from product selection to delivery coordination.

PVC S-1300 is ideal for manufacturing rigid PVC pipes and fittings, PVC profiles and window frames, hard sheets and boards, cable insulation, and high-quality injection molded products.

Partner with Bastone for your PVC S-1300 requirements and experience working with a supplier that prioritizes your success through competitive pricing, technical support, and reliable delivery.

Factory and Activities

Why Choose Bastone PVC Resin-S-1300?

Superior Material Properties

PVC S-1300 resin stands out in the market due to its exceptional polymerization degree of 1250-1350, which directly translates to superior mechanical strength in your final products. This high-grade PVC resin ensures that manufacturers can produce durable, long-lasting items that meet the most demanding industry standards. Whether you're producing pipes, profiles, or injection molded components, the enhanced molecular structure provides the reliability your customers expect.

The apparent density of 0.45-0.52 g/mL makes PVC S-1300 resin ideal for consistent processing and uniform product quality. This consistency reduces production waste and improves your manufacturing efficiency, leading to better cost management and higher profit margins for your business.

Strict Quality Control Standards

PVC S-1300 resin meets the rigorous O/SH3055.77-2007 quality standards, ensuring every batch delivers consistent performance. The residual vinyl chloride monomer content is strictly controlled at ≤2.0 μg/g for Superior grade and ≤5.0 μg/g for Qualified grade, meeting international safety requirements for PVC products. This compliance is crucial for manufacturers targeting export markets or industries with strict regulatory requirements.

The low impurity particle count (≤16 for Superior grade) and minimal "fish eyes" (≤10 per 400cm²) ensure that your finished products have excellent surface quality and appearance. For B2B customers producing high-visibility applications like window profiles or decorative panels, this PVC resin delivers the flawless finish that end users demand.

Excellent End-Product Quality


Products manufactured with PVC S-1300 resin exhibit superior whiteness (≥78% for the Superior grade), providing an ideal base for coloring or maintaining a pristine white finish. This high whiteness value is particularly important for manufacturers producing medical-grade products, food-contact applications, or premium building materials where appearance and purity are critical selling points.

The enhanced impact resistance and mechanical strength of PVC S-1300 resin result in products that withstand harsh operating conditions and have extended service life. Your customers benefit from reduced maintenance costs and fewer replacements, which strengthens your reputation as a supplier of premium quality products.
