Abstract
For low-smoke-type polyolefin compound, LDPE, EVA, and EEA as base resin, magnesium trihydrate, alumina trihydrate, and red phosphorous as flame retardant and MAH type compatibilizer were applied. The amount of each component was changed to find out optimum composition. Mechanical properties were obtained by tensile test and residual stress after aging and flame retardancy was evaluated by smoke density, LOI(Limit Oxygen Index), and UL-94 test. SEM was used for the investigation or morphology and halogen contents were obtained by measuring the amount of HCI. Two kinds of halogen free compositions for flame retardant and low smote resin were found and it is expected to be applied for various purposes.
