Abstract
The instant invention discloses a method for forming glass/polymer alloy or composite pellets of a uniform shape, and exhibiting an increased density and pellet integrity/strength. The pellets are formed by melt-blending and extruding a semi-molten strand of the glass/polymer alloy or composite and subsequently compressing and cutting the strand into pellets at a predetermined pelletizing temperature. The predetermined pelletizing temperature is that temperature at which the glass/polymer alloy or composite extruded strand is still semi-molten and deformable and at which the so-formed pellets will maintain the shape imparted to them.
Claims9
A method for forming pellets of an alloy or composite of glass and polymer of increased density, uniformity and strength, the method comprising
- providing a semi-molten strand of a glass and polymer mixture, and
- deforming and cutting the semi-molten strand into chip-shaped pellets at a predetermined pelletizing temperature, wherein the pelletizing temperature is that temperature at which the strand is still semi-molten and deformable and at which the so-formed pellets will maintain the shape imparted to them.
A method for forming pellets on an alloy or composite of glass and polymer of increased strength and density comprising the steps of:
- a) providing a rod-shaped strand of semi-molten deformable glass and polymer mixture;
- b) deforming and cutting the rod-shaped semi-molten strand at a predetermined pelletizing temperature to form uniformly chip-shaped pellets, wherein the pelletizing temperature is that temperature at which the strand is still semi-molten and deformable and at which the so-formed pellets will maintain the shape imparted to them.
