Clariant Telasperse PVC White 87 Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Telasperse PVC White 87 in PVC formulations?

A: Telasperse PVC White 87 is a high-performance white pigment dispersion specifically engineered for rigid and flexible PVC applications. Its main function is to provide excellent opacity, brightness, and uniform color development while maintaining good processability during compounding and extrusion.

Q2: Is this pigment suitable for food-contact or medical-grade PVC applications?

A: Telasperse PVC White 87 is formulated for general industrial PVC applications and is not pre-qualified for regulated food-contact or medical devices. Customers requiring compliance with food safety or biocompatibility standards must conduct their own regulatory evaluation and validation based on final formulation, processing conditions, and end-use requirements.

Q3: How does Telasperse PVC White 87 differ from standard titanium dioxide powders?

A: Unlike dry TiO₂ pigments, Telasperse PVC White 87 is a ready-to-use liquid dispersion with optimized wetting agents and rheology modifiers. This eliminates dust hazards, improves dispersion efficiency in PVC compounds, reduces mixing time, and enhances batch-to-batch consistency—especially in high-shear processes like calendering or extrusion.

Q4: What are typical dosage guidelines for this pigment in PVC compounds?

A: Dosage depends on the desired whiteness level, opacity requirement, and PVC type (rigid vs. flexible). It is typically used at low concentrations, generally ranging from 0.1% to 2% by weight relative to the total compound, with optimal performance achieved through application-specific optimization.

Q5: Can Telasperse PVC White 87 be used in combination with other Clariant additives or pigments?

A: Yes, Telasperse PVC White 87 is compatible with common Clariant PVC stabilizers, impact modifiers, and organic pigments. However, compatibility testing is recommended when combining with heat stabilizers containing heavy metals or highly reactive co-additives to ensure no adverse interaction affects dispersion stability or thermal performance.
