Raw Materials for PVC Ceiling Panels
Even whiteness and a clean surface for PVC ceiling panels, solid or foamed.
Common problems
- Uneven whiteness when panels are installed side by side
- Wavy surfaces or die lines
- Uneven cell structure in foamed panels
- Panels break easily at the joints
Typical formulation
PVC ceiling panels are judged by their color, so even whiteness matters as much as stable processing. A typical formulation uses K65 resin, stabilizer, impact modifier, lubricants, filler and TiO2 or whitener. Foamed panels also need a blowing agent and processing aid.
Recommended products
Vinora
Suspension PVC homopolymer in four K-value grades, for extrusion, injection, calendering and blow molding.
Calzora
Lead- and barium-free calcium zinc stabilizers, in powder and liquid form for rigid and soft PVC.
Plumbex
Lead-based stabilizers for pipe, roofing, ceiling, gutters, conduit and cable, in low-dust form.
Stannova

OX 316a
A high-density oxidized polyethylene (OPE) wax with a high melting point. Works as external lubricant and metal release agent, and helps control fusion.
TiO2
Titanium dioxide for opacity and whiteness, plus UV protection in outdoor applications.
Pigments & Optical Brightener
Optical brightener, ultramarine blue and mixed pigments for color matching. Color and whiteness stay on target for your product.
Snowbrite DB
A whitener based on TiO2, optical brightener and ultramarine blue. It offsets the yellow tone of the resin and gives high opacity to white PVC products.
