Chemical properties
Tecstar® will withstand oxidizing agents, acids, and highly concentrated base chemicals without its mechanical resistance and strength being affected.
It is highly resistant to chemicals, electrolysis, UV light and temperatures of over 250ºC (steady), and it performs better than other fibers, such as aramids, polyester, polyamides, etc.
It is worth highlighting the fiber’s great resistance to chemicals, hydrolysis, ultraviolet light and the fact that it withstands continuous working temperatures higher than 250°C.
Gases and fumes
The smoke and gases emitted from Tecstar® fiber when exposed to flames are minimal. They are also not opaque, which is crucial for individuals in a fire seeking a rapid evacuation. In many cases, especially in enclosed spaces, the presence of toxic gases, low visibility, and smoke inhalation are more dangerous than the flames themselves.
Below is a table indicating the main fibers in the fire protection market, the smoke density of each, and the time it takes to reach maximum opacity. As shown in the graph, the gases released from Tecstar® fiber are significantly lower compared to other fibers, resulting in much less toxicity.
LOI
The Limiting Oxygen Index (LOI) measures the amount of oxygen needed to sustain combustion. The higher the amount of oxygen used in the mix, the greater the resistance to combustion.
Tecstar® fiber is clearly superior to other fibers used in the market.
The accompanying table provides a graphical representation of the main fibers in the market.
