A thermoset composite material and composite railroad crosstie fabricated from the thermoset composite material that comprises a substantially homogeneous blend of an amount of vulcanized rubber particles, polyurea binding agent and urea melamine. The thermoset composite material may also contain a granulated silica material. The thermoset composite material may comprise about 30% to about 50% by weight of the vulcanized rubber particles, and it is subjected to compression molding at a predetermined temperature and pressure for a resident time period forming the composite railroad crosstie. The thermoset composite material and railroad crosstie may further comprise a fibrous glass material in the form of unbundled fibers and/or one more glass mats encapsulated within the thermoset composite material. In addition or alternatively, an elongated core insert may be encapsulated in the thermoset composite material.

A method reclaims metalized polymer film or mixtures containing metal and/or metal alloys into a metal-containing, polymeric film. The resulting film structure has better oxygen and moisture barrier properties when metalized than plain metalized polymer films. The polymer to be reclaimed, originates in sheet form, and is densified, as by shredding, pelletizing and/or re-extruding into fine particulate form such as chips or pellets. The reclaimed polymeric film can be used, in a range of concentrations, to produce biaxially oriented polyester film for metalizing.

A thermoset composite material that my used in the fabrication of structural components including railroad ties comprise a substantially homogeneous blend of an amount of vulcanized rubber particles including a predetermined ratio of different particles sizes, and a thermoset elastomeric binding agent added to the vulcanized rubber particles. The blend may comprise about 30% to about 97% by weight of the vulcanized rubber particles, and the blend is subjected to compression molding at a predetermined temperature and pressure for a resident time period forming the composite material. The ratio of different rubber particle sizes is selected so that the composite material has a desired density or is within a range of desired densities.

The invention is a method for producing milled elastomer, comprising the steps of directing a liquid jet from at least one nozzle on an elastomeric material moving in an at least partially transversal direction with respect to the discharge direction of the at least one nozzle. In the method according to the invention the liquid jet directed on the elastomeric material has a pressure of 650-1350 bar, and the elastomeric material is moved with respect to the at least one nozzle such that, in a first phase adapted for disintegrating a surface of the elastomeric material, the elastomeric material has a first forward-feed rate of 10 to 20 mm/s at a point of impact of the liquid jet in a direction transverse to the discharge direction, and, in a second phase after disintegrating the surface, the elastomeric material has a second forward-feed rate being decreased with 35-65% compared to the first forward-feed rate. The invention is, furthermore, an apparatus for producing milled elastomer.
