TECSIL and Nextel fiber products which are safe, OSHA-recognized alternatives to potentially hazardous asbestos products. Neither fiber will break down into smaller-diameter fibers under high temperatures, ensuring that they remain large enough to prevent entry into the lower respiratory tract, where much smaller fibers, such as asbestos, often enter and contribute to chronic lung disease.
