Non-halogen flame retardant additive applies 'micro nano silicon' technology

A new non-halogen phosphate flame retardant additive utilizes proprietary "micro nano silicon" to provide flame retardancy in plastics. American Nano Silicon Technologies Inc. (Nanchong, China) is building out a production line with ultimate output of approximately 30,000 tons/yr. The first production line, with 5000 tons of capacity, will begin construction in October 2010, with full capacity reached by the summer of 2011.

Non-halogen flame retardant additive applies 'micro nano silicon' technology

The basic building blocks of micro nano silicon are silicon dioxide and quartz. American Nano Silicon Technologies says the product can chelate calcium and magnesium ions in water, and can act as a substitute for white carbon black in applications in the paper, rubber, plastics, petrochemical, and ceramics industries. The company notes that micro nano silicon can also be used as a substitute for titanium dioxide (TiO2) powder in plastics and other applications.

In 2009, American Nano Silicon Technologies noted that annual demand for flame retardant additives was in excess of 24 million tons. Hoping to tap into that market, the company said that once the completed 30,000 ton production line is in place, it will yield $35 million in revenue with $12 million in net profit annually.

American Nano Silicon Technologies reports that in testing its non-halogen phosphate flame retardant product is comparatively less toxic, with lower smoke density and a minimally invasive odor. Additionally, compared to competitive products, it has a lower specific gravity, requires lower loading levels, and is non-blooming.

American Nano Silicon Technologies, which is a subsidiary of Nanchong Chunfei Nano Silicon Technologies Co. Ltd., supplies its micro nano silicon based products to the concrete and non-phosphate detergent industries, but notes that it is widely used in many consumer and industrial products, including laundry detergent, petrochemicals, plastics, rubber, paper, ceramics, and water treatment materials.

In November 2007, the company announced the start of construction on its 100,000-ton/yr roduction line for micro nano silicon, investing $8 million. The first 50,000 tons of capacity were to be completed and put into production in October 2008. —
