Polychem Middle East's POLY SILICA range provides industrial-grade filler powders, mineral additives, and surface-enhancing materials for composites, GRP, GRC, solid-surface, construction, and industrial manufacturing. Our fillers are known for consistency, purity, and performance — improving mechanical properties, thermal resistance, fire safety, and surface finish while reducing production costs.
The POLY SILICA range is used by composite manufacturers, GRC precast companies, solid surface fabricators, and construction contractors across the UAE, Middle East, and South Asia. All filler products are screened for quality, controlled particle distribution, and batch-to-batch consistency.
Full Product Range
Each filler in the POLY SILICA range serves a specific technical function. Understanding the role of each filler helps manufacturers optimize their formulations for the desired end-product performance.
- Aluminium Hydroxide (ATH) — flame-retardant filler for solid surfaces and GRP
- Calcium Carbonate (CaCO₃) — cost-effective volume filler for GRP, GRC, and putties
- Talc Powder — surface enhancement, workability improvement, and thermal resistance
- Fumed Silica — rheology modifier, thixotropic agent for resins and sealants
- Q-Cell Hollow Microspheres — lightweight filler for reduced density composites
- Cocopit Spill Nil — eco-friendly absorbent powder for oil and chemical spills
- Silica Sand (White, Black Grit, Off-White) — GRC, flooring, blasting, filtration
Technical Applications
ATH is the primary choice for solid surface manufacturers requiring both fire resistance and a bright white base. Fumed Silica is essential in epoxy and polyester adhesive formulations for controlled sag resistance and improved gap-filling. Q-Cell microspheres significantly reduce laminate weight, making them popular in surfboard, fairing compound, and lightweight putty applications.
Fire Safety (ATH)
Aluminium Hydroxide provides flame retardancy and smoke suppression — critical for architectural and furniture composite applications.
Rheology Control
Fumed Silica controls viscosity and thixotropy in resins, adhesives, and sealants for optimal application performance.
Weight Reduction
Q-Cell hollow microspheres reduce material density without sacrificing strength, ideal for lightweight composite structures.
Frequently Asked Questions
ATH (Aluminium Hydroxide) is the primary filler in solid surface and synthetic granite formulations. It provides the white base, improves fire resistance, contributes to hardness, and enables a smooth, workable casting compound with polyester resins.
Fumed Silica acts as a thixotropic agent — it increases viscosity at rest (preventing sag or drainage) while remaining workable under shear (mixing or application). It is essential in vertical epoxy applications, adhesives, and filled coatings.
GRC typically uses a fine to medium grade silica sand (off-white or white) with controlled particle size distribution for consistent surface texture and strength. The sand-to-cement ratio and sand grading significantly affect the surface finish and mechanical properties of GRC panels.
