In a method of integrating an active pharmaceutical ingredient (API) with a thermoplastic polymer, the thermoplastic polymer and API are into a first feed port of a multi-screw extruder or the thermoplastic polymer is fed into the first feed port of a multi-screw extruder, the thermoplastic polymer is conveyed along the heated multi-screw extruder while heating the thermoplastic polymer to a melt temperature of 160° C.-280° C. prior to the thermoplastic polymer being conveyed past a second feed port and the API is fed into the second feeding port in the heated screw extruder to mix with the melted thermoplastic polymer to generate a compounded mixture containing 85-100% of the starting API content. The compounded mixture is extruded from an outlet of the heated screw extruder and cooled via a cooling device such that the compounded mixture contains 85-100% of the starting API content.

A thermoplastic resin pellet is columnar. A cross-sectional shape taken along a plane orthogonal to a height direction of the thermoplastic resin pellet has a longer diameter represented by “a” and a shorter diameter represented by “b”. A ratio a/b is greater than or equal to 1.0, and the ratio a/b is less than or equal to 2.6. A ratio α of a unit height volume of a cylindrical portion of a hopper of a molding machine, into which the thermoplastic resin pellet is loaded, to a volume of the thermoplastic resin pellet is greater than 16. A method for manufacturing an electric cable includes supplying the thermoplastic resin pellet to the hopper, melting the thermoplastic resin pellet in the cylinder to supply molten resin to the die, and extruding the molten resin from the die to form a sheath on a core wire.

Disclosed is a flame-retardant HIPS material and a preparation method thereof, comprising the following components: 90 parts to 67 parts of a HIPS resin; 8 parts to 15 parts of a brominated flame retardant; and 3 parts to 7 parts of an auxiliary flame retardant; wherein the auxiliary flame retardant is a 1,3,5-triazine compound. In the present invention, a synergistic compounding of the brominated flame retardant and the auxiliary flame retardant effectively reduces an amount of the brominated flame retardant, and a stable UL 94 (1.5 mm) V-0 flame-retardant class can be achieved. Compared with the existing brominated flame-retardant HIPS, the present invention has a low halogen content, low gas, and high cost performance ratio, which avoids excessive acid gas from forming air lines on the surface of parts, has a good appearance.
