About this product

Product information from the supplier.

Premium Raw Vermiculite, available in Golden and Silver varieties, is a naturally occurring mineral renowned for its exceptional expansion properties when subjected to high temperatures. As a non-toxic, fire-resistant, and highly porous mineral, it serves as a critical raw material for industries requiring superior insulation, moisture retention, and structural stability. Whether utilized in its raw "crude" form or processed as "expanded" silver vermiculite, this mineral provides unparalleled versatility across agricultural and industrial sectors.

Our high-purity vermiculite is meticulously processed to remove impurities, ensuring a consistent flaky structure that optimizes ion exchange and water-holding capacity. From enhancing soil nutrition in hydroponics to providing high-performance fireproofing in construction, our products are manufactured under strict ISO certified standards. With a wide range of particle sizes and specialized chemical compositions, we provide the ideal solution for sound-absorbing coatings, lightweight concretes, and advanced horticultural growing media.

Frequently Asked Questions

Q: What is the main difference between Golden and Silver Vermiculite?

Golden vermiculite typically refers to the raw ore with specific iron and magnesium content, while Silver vermiculite is the expanded form characterized by its shiny, silvery appearance and lightweight structure.

Q: How is vermiculite used in hydroponics and agriculture?

Expanded vermiculite is used as a growing medium or soil amendment to improve aeration, lighten heavy clay soils, and act as a carrier for fertilizers due to its high ion exchange capacity.

Q: Can crude vermiculite be used directly in construction?

Yes, crude vermiculite is often used in its raw state for producing fireproofing materials, lightweight concrete, and specialized plasters where its inherent mineral properties are required.

Q: Is vermiculite safe for animal hatching and seeding?

Absolutely. Vermiculite is a non-toxic, natural mineral, making it a safe and effective medium for seed germination and maintaining humidity during animal hatching.

Q: What are the typical packaging options for industrial orders?

Our standard packaging is 1.0mt to 1.2mt jumbo bags, although we offer customized packaging solutions to meet the specific logistics requirements of our clients.

Q: What makes your vermiculite suitable for sound-absorbing coatings?

By milling the material either before or after exfoliation, we create a specific particle size range that optimizes the absorption of sound waves in architectural coatings.
