Wholesale Insulation Potting Expanded Perlite Concrete Insulator Per Cryogenic Insulation

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Insulation & Thermal Protection: Expanded perlite provides exceptional thermal insulation for cryogenic applications, construction materials (e.g., concrete), and industrial equipment.
  • Horticultural Support: Acts as a lightweight, porous medium for potting mixes, enhancing drainage, aeration, and nutrient retention in plant cultivation.

Key features

  • 1. Material Technology

    • With expanded volcanic glass material, achieve lightweight insulation and superior moisture retention. Expanded perlite is 40% lighter than traditional rockwool insulation*, making it ideal for cryogenic and construction applications where weight reduction is critical.

  • 2. Interactive Design

    • With customizable sack sizes (100L, variable particle sizes), select the precise quantity and granularity needed for horticulture, insulation, or filtration projects. Offers 3x more size options than standard bulk materials*, ensuring flexibility for diverse use cases.

  • 3. Performance Parameters

    • With high thermal resistance due to its porous structure, maintain cryogenic temperatures or insulate concrete with 30% lower heat transfer compared to fiberglass insulation*. This makes it optimal for extreme temperature environments.

  • 4. Scenario Solutions

    • With versatility across insulation, horticulture, and agriculture, deploy perlite in 5+ applications—from potting mixes to industrial insulation—compared to 2-3 uses in single-purpose materials*. Its lightweight nature simplifies handling in both home and commercial settings.

  • 5. Certification Standards

    • With non-toxic, naturally sourced composition, ensure safe use in food-grade storage or organic farming scenarios. Meets environmental safety standards, unlike synthetic alternatives containing harmful additives*.

Supplier's note

  1. Technical Breakthroughs:

    • Pro Model: Triple the industry-standard chemical resistance enables safe handling of corrosive materials in chemical processing.
    • Advanced Model: Reduced moisture absorption (<0.8%) prevents mold in humid agricultural storage.
    • Base Model: Cost-effective thermal resistance meets 90% of insulation market needs.

  2. Version Selection Guidance:

    • Pro Model: Ideal for cryogenic engineering or chemical industries requiring extreme durability (e.g., LNG storage tanks). With triple-certified chemical resistance, it safeguards against harsh environments.
    • Advanced Model: Optimal for horticulture and food storage, pairing low moisture absorption with lightweight handling.
    • Base Model: Suitable for general insulation in construction or agriculture where cost-efficiency is prioritized.

With the Pro Model’s 30% enhanced thermal resistance, you can achieve energy-efficient insulation in cryogenic systems. The Advanced Model’s moisture control ensures prolonged freshness in stored crops. Choose wisely based on your application’s demands!
