摘要： Extrudable halogen-free mixture comprising 95-5 weight-% polyetherimide polymer with an elastic modulus greater than 2000 MPa and 5-95 weight-% flexible siloxane-polyetherimide copolymer with an elastic modulus of less than 2000 MPa. Electrical cable or wiring insulated with the extrudable halogen-free mixture comprising 60-90 weight-% of a polyetherimide polymer with an elastic modulus greater than 2000 MPa and 40-10 weight-% of a flexible siloxane-polyetherimide copolymer with an elastic modulus of less than 1000 MPa. Electrical or optical cable or tubing sheathed with the extrudable halogen-free mixture comprising 40-10 weight-% of a polyetherimide polymer with an elastic modulus greater than 2000 MPa and 60-90 weight-% of a flexible siloxane-polyetherimide copolymer with an elastic modulus of less than 1000 MPa. The extrudable halogen-free mixtures may additionally comprise reinforcement elements selected from the group consisting of glass fibers, carbon fibers, and mixtures thereof, flame-retardant additives selected from the group consisting of aluminum hydroxide, magnesium hydroxide, and mixtures thereof, and color pigments. The extrudable halogen-free mixtures may be cross-linked. A process for the manufacture of workable granulates of an extrudable halogen-free mixture which comprises the steps of: a.) drying a polyetherimide polymer with an elastic modulus greater than 2000 MPa, b.) drying a flexible siloxane-polyetherimide copolymer with an elastic modulus less than 2000 MPa, c.) combining 95-5 weight-% of said polyetherimide polymer with an elastic modulus greater than 2000 MPa with 5-95 weight-% of said flexible siloxane-polyetherimide copolymer with an elastic modulus of less than 2000 MPa to form a mixture batch, d.) melting said mixture batch to form a melt, and e.) extruding said melt to produce a workable granulate.
