The use of plastic materials requires adequate and increasingly better fire resistance properties; therefore it is important to intervene on the characteristics of plastic materials in order to reduce their flammability through the use of FLAME RETARDANT ADDITIVES.
In particular, with the use of halogen free flame retardants is possible to contrast the ignition and spread of the flame, while avoiding the development of toxic gases during combustion. De Grandi S.r.l. has associated to the micronization and the production of micronized powders a process of chemical synthesis of an intumescent halogen-free flame retardant for the plastics sector. This flame retardant additive, born in the Montell (now Basell) research laboratories, was developed, under exclusive license from De Grandi S.r.l. which then continued in the development and optimizing of the product. The intumescent non-halogenated flame retardant is now called “DG / HF 2000” and can be used for many polymers, especially polyolefins.
