The present invention relates to pellets of a flame retardant long glass fibre reinforced polypropylene composition having a core containing glass fibres and a sheath of a polypropylene compound comprising a flame retardant composition and surrounding said core, wherein the flame retardant composition comprises a mixture of an organic phosphate compound, an organic phosphoric acid compound and zinc oxide. The invention further relates to flame retardant moulding compositions and articles manufactured using the pellets or the moulding compositions.

Disclosed are a carbon nanomaterial pellet and a method for preparing same. More particularly, it relates to a carbon nanomaterial pellet having a specific size and a high apparent density prepared by a simple process using only a rotary tablet press without mixing a carbon nanomaterial powder with a solvent or an additive, which is capable of solving the powder dust problem occurring when preparing a polymer composite from a carbon nanomaterial in the form of powder, thus improving physical properties and remarkably reducing cost of packaging and transportation, and a method for preparing the carbon nanomaterial pellet from a carbon nanomaterial powder.

Disclosed herein is a process for producing a long glass fibre-reinforced thermoplastic polymer composition, comprising the sequential steps of a) unwinding continuous glass multifilament strand containing at most 2% by mass of a sizing composition; b) applying from 0.5 to 20% by mass of an impregnating agent to form an impregnated continuous multifilament strand; and c) applying a sheath of thermoplastic polymer around the impregnated continuous multifilament strand to form a sheathed continuous multifilament strand, wherein the impregnating agent is non-volatile, has a melting point of at least 20° C. below the melting point of the thermoplastic matrix, has a viscosity of from 2.5 to 100 cS at application temperature, and is compatible with the thermoplastic polymer to be reinforced. This process allows trouble-free handling and unwinding of packages, and results in long glass fibre-reinforced thermoplastic products that can be made into articles having good mechanical properties and high quality surface appearance.
