View product → Antioxidante 168 Frequently Asked Questions Which polymers are listed in the Antioxidant 168 TDS? The supplied TDS lists polyethylene (Educação Física), polipropileno (PP), polyamide (PA), policarbonato (computador) and ABS. These are application families, not blanket approval for every formulation or finished article. Confirm the grade, additive package and processing requirements before selection. Pode antioxidante 168 be used alone? The supplied TDS states that it is generally used with phenolic primary antioxidants such as 1010 ou 1076. It does not specify a universal addition level or mixing ratio. Select and evaluate the combination for the actual polymer formulation. Can I qualify a second supply source without changing my approved specification? Use your current approved specification as the starting point and ask whether the proposed supply option can be assessed against it. Keep the document comparison, sample evaluation and internal approval steps separate. A second source should remain a candidate until your qualification process is complete. Can we start a discussion if our formulation is confidential? You can begin with non-confidential information such as the polymer family, aplicativo, processing concern and required product specification. Identify which details cannot be shared openly and ask how a more detailed technical exchange can be arranged. Is a small sample enough to approve a commercial order? A sample can support an initial evaluation, but the scope of approval depends on your qualification procedure and the representativeness of the material tested. Before relying on the result, confirm the sample identity, accompanying documentation and relationship to the proposed commercial grade. What should I do if the received COA differs from the agreed specification? Identify the specific parameter, unit or test method that differs and send the agreed specification together with the relevant COA to the supply contact. Ask for clarification before accepting the material into the approved process.

Antioxidante 168 Guia do comprador

Define the processing problem

Record the resin grade, processing sequence and observed change. Distinguish protection during processing from long-term service performance. Include rework or recycled content where relevant.

Review the complete formulation

Identify existing stabilizers, pigmentos, fillers and processing aids. The TDS describes combinations with phenolic primary antioxidants; it does not prescribe one dosage or blend ratio for every resin.

Compare documents and run a trial

Compare the offered specification, test conditions and batch COA with your approved requirements. Evaluate a candidate under documented processing conditions before approving a production change.

Confirm the supply and end-use requirements

Agree packaging, quantidade, destination and required documents. Check any end-use approvals separately from processing performance. A matching CAS number alone does not qualify a replacement grade.

Antioxidante 168 Perguntas frequentes

Which polymers are listed in the Antioxidant 168 TDS?

The supplied TDS lists polyethylene (Educação Física), polipropileno (PP), polyamide (PA), policarbonato (computador) and ABS. These are application families, not blanket approval for every formulation or finished article. Confirm the grade, additive package and processing requirements before selection.

Pode antioxidante 168 be used alone?

The supplied TDS states that it is generally used with phenolic primary antioxidants such as 1010 ou 1076. It does not specify a universal addition level or mixing ratio. Select and evaluate the combination for the actual polymer formulation.

Can I qualify a second supply source without changing my approved specification?

Use your current approved specification as the starting point and ask whether the proposed supply option can be assessed against it. Keep the document comparison, sample evaluation and internal approval steps separate. A second source should remain a candidate until your qualification process is complete.

Can we start a discussion if our formulation is confidential?

You can begin with non-confidential information such as the polymer family, aplicativo, processing concern and required product specification. Identify which details cannot be shared openly and ask how a more detailed technical exchange can be arranged.

Is a small sample enough to approve a commercial order?

A sample can support an initial evaluation, but the scope of approval depends on your qualification procedure and the representativeness of the material tested. Before relying on the result, confirm the sample identity, accompanying documentation and relationship to the proposed commercial grade.

What should I do if the received COA differs from the agreed specification?

Identify the specific parameter, unit or test method that differs and send the agreed specification together with the relevant COA to the supply contact. Ask for clarification before accepting the material into the approved process.
