Description

Calcium 4-(1,1-Dimethylethyl)Benzoate is a specialty organometallic salt derived from p-tert-butylbenzoic acid. This compound serves as a highly effective and thermally stable additive, primarily functioning as a neutralizing agent and acid scavenger in polymer systems. It is essential for manufacturers in the plastics, synthetic fiber, and lubricant industries who require precise control over acidity to enhance product stability and longevity.

Application

• Polymer Stabilizer: Acts as a neutralizing agent and acid scavenger in polyolefin (e.g., PP, PE) production to protect catalysts and prevent equipment corrosion.
• PVC Heat Stabilizer Component: Used as a co-stabilizer in rigid and flexible PVC formulations to improve long-term thermal stability.
• Lubricant & Grease Additive: Functions as a detergent and neutralizer in industrial lubricants and metalworking fluids to control acidity and reduce sludge formation.
• Synthetic Fiber Production: Employed as a catalyst neutralizer in the manufacture of polyester and nylon to ensure consistent polymer quality and color.
• Adhesive & Sealant Formulations: Enhances the shelf-life and stability of reactive adhesive systems by neutralizing acidic by-products.

Quality Control

Our Calcium 4-(1,1-Dimethylethyl)Benzoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
