Abstract
The flame retardancy and mechanical properties of composites consisting of blends of oil-filled styrene-ethylene/butylene-styrene block copolymer (SEBS) and polypropylene (PP) containing aluminium hydroxide (ATH) or ATH treated with a silane coupling agent (m-ATH) as a flame-retardant filler were examined. A maleic anhydride-grafted SEBS (MA-SEBS) was used as a polymer modifier in some cases. The flame retardancy of the composites improved whereas their tensile strength and elongation at break (EAB) fell with increasing contents of ATH or m-ATH. When the oil-filled SEBS (O-SEBS) was partially replaced with MA-SEBS, the tensile strength of the composites increased but their EAB decreased. Simultaneous replacements of O-SEBS with MA-SEBS and of ATH with m-ATH improved the tensile strength of the composites significantly. Scanning electron microscopy studies showed that the bonding at the particle-matrix interface was improved by the addition of MA-SEBS. 22 refs.
