#CMT# #/CMT# The flame retardant material comprises a matrix (50-65 mass%) comprising an organic polymer and 90 mass% of biopolymer, a flame retardant agent (35-60 mass%) consisting of metal hydroxide, a coupling agent (6-8 mass%) forming an interface between the matrix and the flame retardant agent, and additives and/or fillers. The coupling agent comprises a copolymer of ethylene and vinyl acetate (60 mass%) grafted with maleic anhydride. #CMT#USE : #/CMT# The flame retardant material is useful for manufacturing a housing of electrical equipment or conduits of electrical cables (claimed), and in wire management system such as installation boxes and electrical cabinets, where the housing of electrical equipment or conduits of electrical cables is sockets, circuit breakers, switches or electronic devices such as sensors and regulators. #CMT#ADVANTAGE : #/CMT# The recyclable flame retardant material can be easily molded or extruded, has high flexibility, and ensures simple, reliable and economic manufacture of the housing of electrical equipment conduits of electrical cables with increased resistance to shock and high rigidity. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a schematic cross-sectional side view of an extruder for preparing a material. 1 : First hopper 2 : First feed zone 3 : Sheath 4 : Extrusion end 5 : First compression zone. #CMT#INDUSTRIAL STANDARDS : #/CMT# Preferred Components: The flame retardant material is defined by a standard according to IEC 60695-2-1, and has an elongation at break of greater than 4.5% measured according to the specified procedure in ISO 527. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The flame retardant agent consists of aluminum trihydroxide (30-45 mass%), magnesium hydroxide, calcium/aluminum hydrate and tin oxide hydrate. #CMT#POLYMERS : #/CMT# Preferred Components: The biopolymer consists of 45-65 mass% poly(lactic acid) and polyesters, where a sum of the total percentages of the polyester and the additives and/or fillers is 100 wt.%. The matrix further comprises polymers consisting of polycarbonates, acrylonitrile-butadiene-styrene copolymers, polystyrenes and polypropylenes. |
