Golden Expanded Vermiculite

Product: Golden Expanded Vermiculite

Nature’s Lightweight Wonder for Growth, Insulation & Sustainability

Overview

Golden Expanded Vermiculite is a premium exfoliated mineral derived from natural hydrous phyllosilicate. When rapidly heated (>900°C), it expands 8–15 times its original volume, forming lightweight, accordion-like golden flakes. Renowned for its moisture retention, thermal insulation, and non-toxic properties, it delivers unparalleled versatility across eco-conscious industries.

Key Properties & Advantages

🌟 Striking Aesthetic

• Warm, lustrous golden hue enhances visual appeal in retail horticulture and decorative substrates.

• Reflects light to boost plant vitality in indoor gardens/terrariums.

💧 Superior Water & Nutrient Management

• High cation exchange capacity (CEC: 100–150 meq/100g) retains nutrients and slowly releases them.

• Porous structure holds 200–500% of its weight in water, reducing irrigation frequency.

🔥 Thermal & Acoustic Insulation

• Low thermal conductivity (0.05–0.06 W/m·K) for energy-efficient building materials.

• Fire-resistant (melting point: 1,250°C) and sound-dampening.

🌱 Eco-Friendly & Plant-Safe

• pH-neutral (7.0–7.5), sterile, and asbestos-free.

• Improves soil aeration, prevents compaction, and encourages root growth.

• 100% natural, recyclable, and OMRI-listed for organic use.
