摘要: A method of producing high modulus and strength polymer materials includes compressive rolling a semicrystalline polymer material in at least two different axial directions of the material; and axially orienting at least a portion of the compressive rolled material to a draw ratio less than the ultimate elongation or the elongation % at break of the material.

摘要: A process for flame-retarding base materials, such as fibers or foams with a metal oxide, such as silica, nanoparticle-containing composition and materials including a metal oxide, for example silica nano/micro particle-containing coating, layer, or networks. The process utilized allows properties of the coated material to be maintained. Flame-retarded materials are also disclosed. Heterogeneous dispersions of metal oxide, e.g. silica, particles on fibers or foams on a nanometer scale are described and/or the formation of networks/coatings in porous materials. In a particular embodiment, polymeric foams such as polyisocyanurate, polyurea and polyurethane foams include a metal oxide particle-containing coating layer or network that aids in char formation in the event the material is exposed to a flame.

摘要: An intumescent composition based upon modifications to poly acrylic acid (PAA), including certain additives, is contemplated. Such compositions may be incorporated in epoxy and other resin-based coatings. The PAA may be modified through the use of one or more mineralizing additives to promote char formation.
