Avtec Industries

Avtec’s core technology, TSWB® is a fire retarding and smoke suppressing polymer additive. A non-toxic antimony and bromine-free white powder, TSWB® was created to incorporate into both thermoset and thermoplastic reinforced composites.TSWB® will sharply reduce the propensity of a composite part to combust, generate smoke or transmit heat when exposed to open flame or high radiant heat. TSWB® is a singularly unique composition that chemically reacts at approximately 600˚F (316˚C) to form a charred, cement reinforced surface. This intumescent concretion mitigates surface flammability and smoke development behavior. TSWB® is especially appropriate for end-use applications that require life-safety fire, smoke and toxicity code compliance.

FR Eco-Additive™ is a combination of Avtec’s TSWB® fire retarding and smoke suppressing additive and a crystalline graphite. FR Eco-Additive™ may be combined with composite resins and film forming binders to manufacture paints and coatings. Upon exposure to fire or high radiant heat the TSWB ® mitigates flammability and smoke generation as the graphite expands to form a thick insulating surface covering. This felt-like surface provides fire and heat resistance for assemblies that must meet prescribed burn-through and hourly fire rating criteria, e.g., ASTM E119, UL1709.FR Eco-Additive™ is a non-toxic antimony and bromine-free powder that disperses easily in both solvent and aqueous based resins. FR Eco-Additive™ is available with graphite loading levels of 20, 25 and 30%. Please contact Avtec for a product recommendation specific to the end-product use and fire erformance criteria.
