A reinforcing-fiber composite material includes not less than 20 wt % but less than 70 wt % of discontinuous reinforcing fibers, and a matrix resin, wherein at least a portion of the discontinuous reinforcing fibers forms a fiber aggregation, and at least one bundle of the fiber aggregation has a surface that, when projected onto a two-dimensional plane, has at least one region where the number of monofilaments constituting the aggregation is reduced, at opposite ends in a longitudinal direction of a minimum circumscribed rectangle of the projected surface, and at portions other than the opposite ends.

A compact, highly expandable sorbent made from polymeric materials is contemplated. The resulting sorbent can absorb more than 20 times its original volume owing to an internal foam-like structure having micron-level voids bisected by internal struts which themselves have nano-level pores. Further, this sorbent can be compressed and reused multiple times, thereby making it an ideal substance to facilitate separation of disparate fluids, such as oils floating on or within an aqueous solution.

A polyester film comprising a polymeric phosphonate flame retardant in an amount of from about 1.0 to about 25.0 wt % by total weight of the film and further comprising at least one metal cation selected from the group consisting of Group I and Group II metal cations.

Disclosed are a method of preparing an elastic pressure-sensitive adhesive tape and an elastic pressure-sensitive adhesive tape. Main components of the adhesive include a polyacrylate resin with a carbon-carbon double bond and a diluent monomer with a carbon-carbon double bond. A quasi-microcapsule powder component is adopted, wherein the shell material of the quasi-microcapsule powder selects a cellulose-based water soluble polymer, and the core material selects low boiling point alkane, wherein the preparation method combines UV curing, heating, and shell burst, to obtain an elastic adhesive layer, whereby to prepare a pressure-sensitive adhesive tape product. Compared with conventional elastic pressure-sensitive adhesive tapes, the preparing method as disclosed has a simple manufacturing process. The pressure-sensitive adhesive tape obtained from the disclosed preparing method overcomes the restrictions of conventional foam strips and provide good cushioning and compression properties without using foam as the carrier.
