About this product
Product information from the supplier.
Vermiculite is a high-performance hydrous phyllosilicate mineral renowned for its extraordinary exfoliating properties when heated. In the non-metallic mining and manufacturing sector, this mineral is prized for its ability to expand significantly, creating a lightweight, porous structure that provides exceptional thermal insulation and moisture regulation, making it an indispensable material across industrial and agricultural applications.
Our premium-grade Vermiculite is processed using advanced mineral separation and expansion technologies to ensure consistent particle size and purity. Whether utilized as a fire-resistant additive in construction, a sterile growth medium in horticulture, or a high-efficiency absorbent in industrial spills, our product delivers superior stability and performance that meets rigorous international quality standards.

Frequently Asked Questions
Q: What makes Vermiculite different from Perlite?
Vermiculite has a higher cation exchange capacity (CEC) and superior water retention compared to Perlite, making it more effective for nutrient holding in agricultural use.
Q: Is this product safe for indoor construction?
Yes, our Vermiculite is processed to be free of harmful contaminants and is widely used in fireproof plasters and ceiling insulation.
Q: How does the expansion process affect the mineral's properties?
Rapid heating causes the mineral to "pop" like popcorn, creating an accordion-like structure that traps air, resulting in low density and high insulation.
Q: Can Vermiculite be reused in gardening applications?
Yes, due to its chemical stability and resistance to decay, it can be sterilized and reused in potting mixes multiple times.
Q: What are the typical packaging options for industrial orders?
We provide various options including jumbo bags, 25kg PP bags, and bulk shipping containers tailored to your logistics needs.
Q: Does Vermiculite provide soundproofing benefits?
Yes, its porous nature effectively absorbs sound waves, making it an excellent additive for acoustic panels and sound-dampening walls.
