Disclosed are continuous compression molding processes for producing a flexible polyurethane foam laminate and laminates produced thereby, which may be suitable for use, for example, as a carpet underlayment.

Processes for producing flexible polyurethane foam laminates and laminates produced thereby

Disclosed are tufted carpet structures, including synthetic turf structures, such as synthetic grass structures, that include a polyurethane backing coating formed from a polyether carbonate polyol.

Disclosed are free-flowing particles. These free-flowing particles include: (a) a rubber particle, and (b) a coating deposited over at least a portion of the rubber particle, wherein the coating includes: (1) a polyurethane-urea resin that is a reaction product of a reaction mixture comprising: (i) a polyol having a number average molecular weight of 1800 to 12,000; (ii) an aromatic diamine; (iii) a polyisocyanate; and (iv) a catalyst for the reaction between hydroxyl groups and isocyanate groups; and (2) a solid particle anti-clumping agent. Also disclosed are methods of making and using such free-flowing particles and synthetic turf structures that include an infill of such free-flowing particles.
