Abstract: The present invention relates to a method for reducing an amount of glass filaments separating from pellets comprising a thermoplastic polymer sheath intimately surrounding the glass filaments. The method can include transporting the pellets through a piping system and/or by a vibrating conveyor means. The pellets have a length of at least 13 mm. The amount of glass filaments separating from the pellets when such pellets are subjected to repetitive mechanical loads in transportation is reduced as compared other pellets subjected to the same repetitive mechanical load, such that blocking caused by the glass filaments within the pellet transport system is reduced or eliminated as compared to transporting pellets having a length of less than or equal to 12.1 mm.

Abstract: Method for treatment of pellets (1) comprising a thermoplastic polymer sheath (2) surrounding glass filaments (3), which glass filaments are covered at least in part with an impregnating agent and extend in a longitudinal direction of the pellets, the method comprising maintaining the pellets for a period of time at an elevated temperature. The method results in an improved impregnation of glass filaments in the pellets resulting in (a) lower amounts of glass separating from the pellets when such are subjected to repetitive mechanical loads and (b) less agglomerations of glass filaments in moulded products manufactured from the pellets.

Abstract: The present invention relates to the use of pellets having a length of at least 13 mm and comprising a thermoplastic polymer sheath intimately surrounding glass filaments, which glass filaments are covered at least in part with an impregnating agent and extend in a longitudinal direction of said pellets, for reducing the amount of glass filaments separating from the pellets when such pellets are subjected to repetitive mechanical loads.

Abstract: The present invention relates to a pellet transportation system comprising at least one of a piping system and a vibrating conveyor belt and pellets in or on the pellet transport system. The pellets have a length of at least 13 mm The the amount of glass filaments separating from the pellets when such pellets are subjected to repetitive mechanical loads in or on the pellet transport system is reduced as compared other pellets subjected to the same repetitive mechanical load, such that blocking caused by the glass filaments within the pellet transport system is reduced or eliminated, wherein the only difference between the pellets and the other pellets is that the other pellets have a length of less than or equal to 12.1 mm
