Polyvinyl Chloride (PVC) resin

Description

1. Product Overview
Polyvinyl Chloride (PVC) Resin is a high-molecular-weight thermoplastic polymer produced via suspension polymerization, recognized globally as the third most widely produced synthetic plastic polymer. It serves as the essential raw material for rigid and flexible applications across construction, automotive, and electrical industries. The key value proposition lies in its exceptional cost-efficiency, chemical resistance, and processability, enabling manufacturers to achieve high durability and design flexibility at scale. Strategically, PVC resin remains irreplaceable in emerging markets due to its low carbon footprint during production compared to alternative thermoplastics, making it a critical enabler for resilient, long-life infrastructure.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Polyvinyl Chloride homopolymer (CAS No. 9002-86-2), suspension grade (SG-3, SG-5, SG-7, SG-8 variants)

• Purity Level: ≥ 99.9% (volatile matter ≤ 0.3%, ash content ≤ 0.1%)

• Physical Characteristics: White free-flowing powder; K-Value range 65–72 (depending on grade); particle size D50: 150–250 microns; apparent density 0.50–0.60 g/mL; residual VCM ≤ 1 ppm

• Packaging Options: 25 kg multi-walled paper or PP woven bags with PE liner; 1,000 kg FIBC bulk bags; pneumatic tanker delivery for silo storage

• Shelf Life: 12 months in original unopened packaging stored below 30°C, away from direct sunlight and moisture

3. Core Industrial Applications

• Construction (Rigid PVC): Window profiles, pipes (potable water, sewer, conduit), siding, and fittings – outperforms metal and concrete in corrosion resistance and weight, reducing installation costs by up to 30%.

• Automotive (Flexible & Semi-rigid): Underbody coatings, interior trims, cable wiring insulation – provides superior flame retardancy and thermal stability compared to polyolefins, meeting ISO 6722 and SAE J1128 standards.

• Electrical & Electronics: Wire and cable jacketing, plug housings – offers high dielectric strength (≥ 40 kV/mm) and low smoke emission, ensuring compliance with RoHS and REACH.

• Healthcare (Medical Grade): Blood bags, tubing, IV containers – plasticized variants offer transparency and sterilizability (EtO, gamma) without embrittlement, outperforming EVA in puncture resistance.

4. Competitive Advantages

• Quality Consistency: Lot-to-lot uniformity guaranteed via real-time NIR spectroscopy and ISO 9001:2015 certified process control; fish-eye count < 5 per 100 cm².

• Supply Reliability: Backed by multiple production sites and 30-day safety stock buffer; lead time 15–25 days ex-warehouse.

• Logistics Capability: Dedicated containerized shipping with anti-humidity linings; door-to-door tracking via portal API for B2B integration.

• Price Competitiveness: Index-linked pricing (ICIS, S&P Global) with volume tier discounts; long-term contracts available for >500 MT/month.

• Sustainability: Recyclable via mechanical and feedstock recycling pathways; available with 15–30% post-industrial recycled (PIR) content upon request. EPD (Environmental Product Declaration) documentation provided on demand.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20 MT (twenty metric tons) per shipping lot

• Loading Capacity: 22–27 MT per standard 20FT container (depending on bag type); 25–27 MT per 20FT using FIBC bulk bags; pneumatic bulk tankers: 24 MT per trailer
