CAS 4980-54-5
Product Overview
Zinc p-tert-butylbenzoate (CAS 4980-54-5), with the molecular formula C₂₂H₂₆O₄Zn, is an organic zinc carboxylate appearing as white or pale yellow fine powder. It serves as a core component in calcium-zinc composite stabilizer systems for flexible transparent PVC materials. This organozinc additive captures hydrogen chloride released during PVC thermal processing, effectively inhibiting zinc burning and yellowing, while providing internal and external lubrication to improve plastic processing fluidity.
This chemical additive exhibits excellent compatibility with polymer matrices, helping preserve the high transparency of finished PVC products and lowering the risks of precipitation and oil bleeding. Apart from plastic stabilization, it can be used as a nucleating agent for polypropylene to enhance the surface gloss of polymer products. It also functions as a resin modifier in coating formulations, improving the weather resistance and color retention of paint films. Furthermore, it can serve as an auxiliary catalyst and organic synthesis intermediate in fine chemical production.
Our Zinc p-tert-butylbenzoate is manufactured under rigorous quality control protocols. We ensure consistent zinc content and low heating loss across all batches. The standard packaging is a 25kg woven bag lined with a PE inner bag, and custom packaging is available upon request. Each shipment comes with COA, MSDS and other supporting documents to assist incoming quality inspection and import customs clearance. Our technical team can provide formulation recommendations for your polymer compounding process. Whether you need laboratory-scale sample trials or continuous large-volume bulk supply, we can arrange delivery schedules to align with your production cycle.

FAQ
Q1: What is the primary application of Zinc p-tert-butylbenzoate?
A1: It is mainly used as a heat stabilizer and lubricant for transparent flexible PVC products and is commonly incorporated into calcium-zinc stabilizer formulas.
Q2: What is zinc burning? Can this product resolve this issue?
A2: Zinc burning refers to the rapid degradation of PVC caused by excess zinc chloride. This product can suppress this phenomenon and prevent yellowing in transparent PVC.
Q3: What are the appropriate storage conditions?
A3: Store in a cool, dry and ventilated warehouse. Keep containers sealed and away from moisture, high temperatures and direct sunlight.
Q4: Can I obtain samples before bulk purchase?
A4: Yes, we provide small-quantity samples for laboratory formulation and quality evaluation.
Q5: What documents can you provide for export shipments?
A5: We can supply COA, MSDS, commercial invoice and packing list to satisfy customs clearance requirements.
