摘要:
The invention relates to a glass fiber-reinforced thermoplastic polymer composition comprising a sheathed continuous multifilament strand comprising a core that extends in the longitudinal direction and a polymer sheath which intimately surrounds said core, wherein the core comprises an impregnated continuous multifilament strand comprising at least one continuous glass multifilament strand, wherein the at least one continuous glass multifilament strand is impregnated with an impregnating agent, wherein the polymer sheath consists of a thermoplastic polymer composition comprising a thermoplastic polymer, wherein the glass fiber-reinforced thermoplastic polymer composition comprises a liquid color composition comprising a pigment and a liquid carrier comprising a dicarboxylic acid ester and/or an unsaturated long-chain aliphatic fatty acid having 13 to 21 carbon atoms.

A multilayer film includes: a first outer layer and a second outer layer; a first inner layer positioned between the first outer layer and the second outer layer and adjacent to the first outer layer; and a second inner layer positioned between the first inner layer and the second outer layer; wherein the first and second inner layers are formed of a polymer including a glass transition temperature less than or equal to about 150° C. and a melt temperature of at least about 47° C.; and wherein, upon sealing, the first outer layer, the second outer layer, the first inner layer and the second inner layer provide a sealed multilayer film including a hot tack strength of at least about O.IN as determined by ASTM F1921 (2012), method B (based on a 15 mm width strip of film). Also provided herein are methods of making the multilayer films and packages formed from the multilayer films.

摘要:
An apparatus and methods of mixing materials in a silo that includes a mixing chamber (2) with an outlet (23) the bottom and an inlet hose (4) connected to an inlet opening at the top; a sieve (16) at the top of the mixing chamber above the inlet opening and below the outlet opening to prevent contact between a particulate mixing material and the top of the mixing chamber and to allow dust through; a pump system (18) to create a negative pressure region at the top of the mixing chamber; and an air manifold assembly (8), which includes an air pressure manifold (10) having an air nozzle (12) to introduce an air stream into the mixing chamber and an air manifold cover (14) to prevent contact between the particulate mixing material and the air pressure manifold, and to allow a particulate mixed product material to pass to the mixing chamber outlet.
