Tinuvin price manufacturers

When sourcing Tinuvin (typically HALS or UV absorbers), you must evaluate the Active Content percentage, which should ideally be ≥99%. Pay close attention to the Melting Point range (e.g., 80-85°C for Tinuvin 770) and Volatility levels, as these directly impact the stabilizer's performance during high-temperature plastic processing. Ensure the Ash content is <0.1% to prevent impurities from affecting the final product's clarity or mechanical properties.

The price varies significantly based on the chemical structure: Tinuvin 770 (Low molecular weight HALS) is generally more cost-effective for thick sections, while Tinuvin 622 (High molecular weight HALS) commands a premium due to its low volatility and migration resistance, making it essential for thin films or fibers. UV absorbers like Tinuvin 326 are priced based on their specific ability to protect PP and PE against yellowing, often requiring a higher purity grade for food-contact applications.

Suppliers must provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For exports to Europe, REACH registration is mandatory. If the end product is for food packaging, the Tinuvin grade must comply with FDA (US) or EU No 10/2011 regulations. Ensure the supplier follows ISO 9001:2015 quality management systems to guarantee batch-to-batch consistency.

Do not look at the unit price in isolation; calculate the Cost-per-Performance ratio. A cheaper, low-purity stabilizer may require a higher dosage (e.g., 0.5% vs 0.2%) to achieve the same UV resistance, ultimately increasing the total production cost. Request Accelerated Weathering Test (QUV) reports from the supplier to verify that the additive effectively extends the product lifespan relative to its price.

The biggest risk is product adulteration or dilution, where high-value HALS are mixed with cheaper fillers. To mitigate this, use Made-in-China.com's Secured Trading services and insist on third-party pre-shipment inspections (like SGS or Intertek) to perform FTIR (Fourier Transform Infrared Spectroscopy) testing, which confirms the chemical identity of the powder or granules.

Negotiations should be based on volume-based tiers and raw material index pricing (e.g., tracking the cost of intermediate amines). Aim for a 10-15% discount on orders exceeding 5 metric tons. Additionally, negotiate for palletized packaging and moisture-proof vacuum sealing included in the price to prevent degradation during long-sea transit.

Tinuvin is generally classified as non-hazardous for transport, but it is sensitive to heat and moisture. Ensure the shipping documents include a Non-Hazardous Chemical Declaration to avoid customs delays. For shipping to global destinations, use FOB or CIF terms and ensure the cargo is stored away from heat sources on the vessel to prevent clumping or chemical degradation.

Always verify the supplier's Business License and Export Permits on the Made-in-China.com platform. Utilize Audit Reports to check if the supplier is a genuine manufacturer or a middleman. For first-time orders, use Letter of Credit (L/C) or Escrow payment terms to ensure funds are only released upon verification of the shipping documents and quality compliance.
