Our products form an essential part of environmentally compatible fire safety solutions and share the common concept of an ideal flame retardant as one which: Is not toxic to humans, animals and plants.Does not migrate out of finished products.
Does not release additional toxic or corrosive gases in case of fire.Does no impede the recycling of finished articles.
Is either degradable in the environment or remains neutral as naturally occurring substances.
