Antioxidant TNPP
Antioxidant TNPP from East Ocean Chemical Co., Ltd is a colorless to clear yellow viscous liquid used as a stabiliser in polymers and lubricants. It meets strict quality parameters: Colour at 60 max APHA, Acid Number at 0.1 max mg KOH/g, and Refractive Index at 1.523 - 1.528 at 25°C. The product has a viscosity of 2500 - 5000 mPa.s at 25°C and a specific gravity of 0.980 - 0.992 g/cm³, with a phosphorus content of 3.8% minimum and free nonyl phenol capped at 5% maximum.
This antioxidant is a thioester-based compound, typical for industrial applications where thermal and oxidative stability are critical. It is commonly used in polyolefins, PVC, and synthetic rubbers to prevent degradation during processing and end-use. The standard form is a liquid, packed in 200 kg drums, which is typical for bulk chemical handling and logistics in polymer manufacturing.
Buyers in the plastics, rubber, and lubricant industries source TNPP to extend the lifespan of their products under high-temperature conditions. It is particularly valued in applications where long-term stability against UV and heat exposure is required. For bulk orders, confirm packaging compatibility and handling requirements, as the product is sensitive to moisture and requires sealed storage.

Sourcing Antioxidant TNPP from East Ocean Chemical Co., Ltd - China Import Guide
Before ordering TNPP from East Ocean Chemical Co., Ltd, verify the supplier’s current production capacity and lead times, as response metrics are not publicly updated.

Logistics for TNPP typically involve sealed 200 kg drums, which are standard for bulk chemical shipments. Discuss Incoterms such as FOB or CIF with the supplier to clarify responsibility for freight and insurance.

Quality checks for TNPP should include testing for Colour (APHA), Acid Number, and viscosity at 25°C. Inspect the drums for leaks or damage upon delivery, and store the product in a dry, temperature-controlled environment. Documentation such as the CoA and Material Safety Data Sheet (MSDS) should accompany the shipment to confirm its suitability for your application.
