High-Quality Industrial-Grade Vermiculite, Suitable For Agriculture And Sachet Making

Features

This type of vermiculite, relying on the unique structure of natural mica minerals, can expand several times to more than 20 times in volume after high-temperature roasting, forming a layered and porous lightweight structure with excellent physical and chemical properties. 

Application scenario

Its core advantages play a significant role in various application scenarios. In the field of horticultural seedling raising, the porous structure of expanded vermiculite gives it excellent air permeability, water retention, and fertilizer retention performance.

It can effectively loosen the soil, adjust soil pH, improve soil air permeability and drainage, prevent soil compaction in flowerpots, and at the same time provide sufficient oxygen and water for the growth of plant roots, improving seed germination rate and seedling survival rate. It is a high-quality substrate for flower, vegetable, and seedling raising as well as soilless cultivation, and can also be used as a special filler for paved road surface and succulent planting.

In the field of building insulation, the lightweight and porous characteristics make vermiculite have excellent thermal insulation, heat insulation, and sound insulation effects.  It is the core raw material for building insulation and refractory materials such as insulation mortar, insulation boards, and fireproof boards.

Which can effectively reduce building energy consumption, and at the same time has fire-resistant and flame-retardant properties, improving the building's fire protection level.In the field of refractory materials and metallurgical casting, vermiculite is resistant to high temperatures and has low thermal conductivity. It can be used as aggregate for refractory castables and coatings, as well as demolding agents and insulation covering agents in the casting industry, effectively improving casting quality and reducing high-temperature loss. 

In the field of soil improvement and environmental protection, its layered structure has strong ion exchange and adsorption capacity, which can be used to improve saline-alkali land and acidic soil, adjust soil physical and chemical properties, and can also adsorb heavy metal ions and harmful impurities in water, being applied to sewage treatment and water purification.

In addition, vermiculite can also be used in scenarios such as water quality regulation in aquaculture, moisture absorption and deodorization of pet bedding, and filling of thermal insulation materials, adapting to the diversified use needs of multiple industries.

Advantages

Chuangwei Minerals has a standardized vermiculite production and processing workshop, equipped with professional crushing and screening, high-temperature roasting and expansion equipment, as well as a complete quality control and testing system. 

From the procurement of natural vermiculite ore, grading and screening to high-temperature roasting and finished product particle size sorting, multi-link sampling tests are carried out on core indicators such as expansion rate, porosity, bulk density, refractoriness, and particle size uniformity of the products throughout the process to ensure that the expanded vermiculite meets the standard in terms of fluffiness, has no agglomeration, and the raw vermiculite flakes have high purity and few impurities. All products meet industry usage standards. 

Quality & Service

The product specifications are complete, with conventional particle sizes such as 1-3mm for seedling raising, 3-6mm for insulation, and 6-10mm for casting available for direct delivery from stock. 

Special meshes and customized particle sizes can be processed on demand with a short delivery cycle, which can meet the different needs of small-batch horticultural procurement, large-batch engineering, and industrial production. 

The product packaging adopts moisture-proof and wear-resistant woven bag design with an inner film to prevent leakage. It can be customized into 25kg, 50kg conventional specifications and large-tonnage bulk packaging, effectively avoiding moisture and compaction problems during transportation and storage. 

The manufacturer supplies directly from the source without middlemen, with favorable prices for large quantities. It has a complete national logistics distribution system, supporting full truckload and less-than-truckload shipments. 

At the same time, it provides one-on-one pre-sales consultation, can provide professional suggestions on specification selection and usage ratio according to customer application scenarios, and has a complete after-sales guarantee service, creating a one-stop vermiculite procurement experience for customers in various industries such as horticultural planting, building insulation, refractory metallurgy, and environmental protection engineering, helping downstream enterprises reduce costs, increase efficiency, and enhance the use value of products.
