Basalt fibers together with carbon or ceramic fibers as well as various metals is the most advanced and exciting area of application, Normal coefficient of sound absorption 0,9 – 0,99 0,8 – 0,93 the resulting basalt – plastic acquires shield properties against electromagnetic radiation Additionally, basalt fibers are naturally resistant to ultraviolet (UV) and highenergy electromagnetic radiation, maintain their properties in cold temperatures, and provides better acid resistance Reportedly, basalt also is superior in the realm of worker safety and air quality as wellBasalt Fibers: Alternative to Glass? CompositesWorld EARLY BASALT FIBERS Paul Dhé from Paris, France, was the first with the idea to extrude fibers from basalt He was granted a US patent in 1923 Around 1960, both the US and the former Soviet Union (USSR) also began to investigate basalt fiber applications, particularly for military hardware, such as missilesBasalt Fibers: a new alternative to Glass?Basalt is a common extrusive volcanic rock An inert rock found worldwide, basalt is the generic term for solidified volcanic lava Safe and abundant, basalt rock has long been known for its thermal properties, strength and durability It is formedAN INTRODUCTION TO BASALT ROCK FIBER AND Basalt vs Glass Fibers Low water absorption properties; Resistance to electromagnetic radiation; Fireblocking tests performed by Basaltex placed its basalt fabric in front of a Bunsen burner, placing the yellow tip of the flame in direct contact with the fabric The yellow tip reaches temperatures of 1100°C to 1200°C (2012°F to New Product Basalt Tadpole Seals Made in the USA
