Q1: What is the primary function of Solvay STRONTIUM CARBONATE D Pigment in polymer systems?
A: It serves primarily as a functional pigment and acid scavenger, helping to stabilize polymers during high-temperature processing by neutralizing acidic degradation products—particularly beneficial in polyolefins and engineering thermoplastics.
Q2: Is this pigment suitable for food-contact or medical-grade polymer applications?
A: Solvay STRONTIUM CARBONATE D Pigment is designed for industrial and technical polymer applications. For food-contact or medical uses, regulatory compliance must be confirmed case-by-case with local authorities and end-product specifications; it is not pre-approved for such applications by default.
Q3: How does STRONTIUM CARBONATE D differ from standard strontium carbonate grades?
A: STRONTIUM CARBONATE D is a specially surface-treated, free-flowing grade optimized for dispersion in polymer melts. It offers enhanced thermal stability and reduced dust generation compared to conventional strontium carbonate powders, supporting more consistent dosing and improved processability.
Q4: What are typical handling and storage recommendations?
A: Store in a cool, dry environment in original sealed packaging to prevent moisture absorption. Handle using appropriate engineering controls (e.g., local exhaust ventilation) and personal protective equipment (PPE), as with any fine inorganic powder, to minimize inhalation of airborne particles.
