The disclosed retroreflective element includes a polymeric core that is loaded with a plurality of first beads and second beads distributed at the perimeter of the core. The first beads are different than the second beads. Because of the beads in the core, the retroreflective element remains useful for returning light even after portions of the core begins to wear away. Further, when the retroreflective elements get wet, water will settle to the bottom of the perimeter of the core. Therefore, using the second beads with a refractive index suited for wet conditions, while the first beads have a refractive index suited for dry conditions allows the retroreflective element to be useful in both wet and dry conditions even while the retroreflective element wears during use.

The invention relates to a heat-sealable paperboard comprising a paperboard substrate (1) comprising a first side and a second side, a first dispersion coating layer (2) on the first side of the paperboard substrate (1), and a second dispersion coating layer (3) on the first dispersion coating layer (2), wherein the first dispersion coating layer (2) comprises a latex and pigment and the second dispersion coating layer (3) comprises a polyolefin.

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.

A method for generating a shingle roof coating is described. The method includes receiving an asphalt feedstock and separately proceeds to mix an elastomeric polymer and an asphalt flux to generate a first concentrate. The first concentrate is then heated separately from the asphalt feedstock. The method then mixes the first concentrate with the asphalt feedstock and heats the combined first concentrate and the asphalt feedstock to generate the shingle roof coating. The amount of elastomeric polymer in the first concentrate is adjusted based on the type of asphalt feedstock such that the resulting shingle roof coating includes 0.5% to 6% by weight of the elastomeric polymer.
