Abstract: A die assembly (5) including: (i) a die plate (10) having an inlet surface (15) and an opposing discharge surface (35); (ii) an inlet (30) on the inlet surface (15) and a first axis of symmetry (A) extending through the inlet (30) and perpendicular to the inlet surface (15); (iii) a discharge port (45) on the discharge surface (35) and a second axis of symmetry (B) extending through the discharge port (45) and perpendicular to the discharge surface (35). The first and second axes are apart from, and parallel to, one another. The die assembly (5) includes (iv) an extrudate passage (42) fluidly connecting the inlet (30) and the discharge port (45). A third axis of symmetry (C) extends through the extrudate passage (42). The die assembly (5) includes (v) a nozzle (100) mounted in the die plate (10), the nozzle (100) having an injection tip (110) in the extrudate passage (42) at the discharge port (45); and (vi) the third axis of symmetry (C) intersects the first axis of symmetry (A) to form an acute angle.

Abstract: Disclosed is an effective thermal grease comprising a hyperbranched olefinic fluid and a thermally conductive filler. Property-modifying additives and fillers may also be included. The hyperbranched olefinic fluid is selected to have an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. The thermal grease exhibits a flash point of 180° C. or higher, a pour point of 0° C. or lower, and a kinematic viscosity at 40° C. of no more than 200 cSt (0.0002 m 2/s). The composition may offer improved thermal conductivity, reduced tendency to migrate, and lower cost when compared with many other thermal greases, including silicone-based thermal greases.
