Quartz Silica 200 Mesh

Product Overview

Quartz Silica Powder is a high-purity, crystalline mineral additive ideal for reinforcing composite systems. With a verified SiO₂ content of 98.5%, this mineral is optimised for use in FRP applications requiring abrasion resistance, thermal conductivity, and mechanical strength. The 200 mesh size ensures excellent dispersion in resin systems and reliable performance in demanding structural and industrial applications.

Key Benefits

• Superior Abrasion Resistance
  Enhances the durability of epoxy flooring, toolings, and laminates by increasing surface hardness.

• High Thermal Conductivity
  Ideal for electrical insulation, heat-resistant tooling, and fire-rated laminates where heat dissipation is important.

• Mechanical Reinforcement
  Boosts compressive strength and wear resistance in filled systems such as gelcoats, repair mortars, and casting resins.

• Excellent Chemical Stability
  Chemically inert, quartz powder maintains integrity in acidic and alkaline conditions — ensuring long-term stability.

• Controlled Particle Size (200 Mesh)
  The fine 200 mesh grade provides an optimal balance between workability and structural reinforcement.
