Four core product lines — PVC resins, paste resin, plasticizers, and acetylene carbon black — backed by factory-level partnerships that give us real influence over grade, formulation, and specification.
Suspension-polymerized PVC Resin supplied through our long-term factory partnerships. Each grade is defined by its K-value — a direct measure of average molecular weight — which governs processability, mechanical strength, and end-use suitability.
Available in 25 kg woven bags or 1,000 kg jumbo bags. Standard load per FCL: 18 MT (20' container) or 26 MT (40' container). Full Certificate of Analysis (COA) and MSDS are provided with every shipment.

| K58 | 0.60 g/ml | ≤ 0.3% | ≤ 1 PPM |
| K67 Popular | 0.57 g/ml | ≤ 0.3% | ≤ 1 PPM |
| K70 | 0.51 g/ml | ≤ 0.3% | ≤ 1 PPM |
| K72 | 0.46 g/ml | ≤ 0.3% | ≤ 1 PPM |
Emulsion-process and micro-suspension PVC paste resin engineered for plastisol and organosol applications. Ultra-fine particle size distribution ensures smooth paste formation, excellent viscosity stability, and consistent film quality across coating and dipping operations.
Our factory partnerships allow us to align the viscosity grade and particle size profile to your specific formulation requirements — not just ship a standard product off the shelf. Basic compatibility data with common plasticizers such as DOTP, DINP and DOP can be provided upon request.

We supply the three primary plasticizers used in PVC compounding: DOP (dioctyl phthalate, general purpose), DOTP (dioctyl terephthalate, phthalate-free, REACH-compliant), and DINP (diisononyl phthalate, high molecular weight, low volatility). Supply ratios and blend combinations can be coordinated to complement your existing formulation.
Available in 200 kg galvanized drums. Full COA, MSDS, and packing list on every shipment.
| Product | Ester | APHA Colour | Flash Point |

| DOP | ≥ 99.5% | ≤ 20 | ≥ 195℃ |
| DOTP | ≥ 99.5% | ≤ 15 | ≥ 210℃ Eco |
| DINP | ≥ 99.5% | ≤ 20 | ≥ 219℃ |
Manufactured by the controlled exothermic decomposition of high-purity acetylene gas, our carbon black is characterized by its high crystallinity, high structure, and exceptional purity. This unique 3D chain-like spatial network delivers superior electrical conductivity and maximizes liquid absorption — critical for lithium battery electrolyte retention.
Available in standard powder form and compressed pellet form — pellet grade is recommended where dust control and handling efficiency are priorities. Standard packaging consists of 10 kg kraft paper bags, palletized for secure container loading, with custom packaging solutions available upon request. Full lot traceability, COA, and MSDS are provided with every shipment.
