  • 3. Performance Parameters

    • With high thermal resistance (R-value of 4.0 per inch), reduce energy consumption by 15%* in building insulation applications, outperforming standard mineral wool.

  • 4. Scenario Solutions

    • Versatile for both fireproof coatings in commercial buildings and as a lightweight, sterile growing medium in horticultural projects, adapting to diverse needs from construction to agriculture.

  • 5. Certification Standards

    • Certified to ASTM E119 fire-resistance standards and eco-friendly for sustainable applications, ensuring compliance with global safety and environmental regulations.

Product details

Fire Retardant Expanded Perlite Fireproof Coating Filter Expanded Perlite

Fire Retardant Expanded Perlite is a versatile mineral-based material designed for applications requiring thermal insulation, fire resistance, and lightweight durability. Its expanded granular structure and fine particle uniformity make it ideal for agriculture, horticulture, and construction. The decorative presentation in the image highlights its clean, consistent texture, suitable for both functional and aesthetic uses.

Technical specifications

FeatureSpecificationBenefit
MaterialExpanded perlite with fire-retardant additivesLightweight, non-combustible, and chemically stable
Fire ResistanceExceeds 1200°C for 2 hours (ISO 834)Prevents fire spread in high-risk areas
Particle Size0.1–2 mm (adjustable)Ensures precise application in coatings or filters
Density30–80 kg/m³30% lighter than traditional insulation materials
pH LevelNeutral (6.0–7.5)Safe for agricultural and horticultural use

Customization guide

Adjustable parameters include particle size distribution (for tailored porosity in filters) and additive blends (to enhance fire resistance or chemical stability). For example, finer particles (0.1–0.5 mm) are optimal for fireproof coatings, while coarser grades (1–2 mm) suit construction insulation.

Supplier's note

  1. Three Technical Breakthroughs:

    • Enhanced Fire Resistance: The Pro Model’s 1560°C rating triples industry benchmarks, enabling use in extreme environments like industrial kilns.
    • Precision Particle Control: Adjustable granule sizes allow tailored porosity, critical for efficient filtration in HVAC systems.
    • pH Neutrality: Maintains soil health in horticulture while resisting chemical degradation in construction.

  2. Optimal Version Selection:

    • Base Model: Ideal for general construction insulation or agricultural soil conditioning where cost-efficiency is key.
    • Advanced Model: Best for HVAC filters or moderate fire-risk zones, leveraging its fine particles and tighter pH control.
    • Pro Model: Required for high-temperature applications (e.g., industrial ovens) where extreme durability and lightweight are critical. With its 30% lower density than alternatives, it reduces structural load while exceeding safety standards.
