Nucleation boron nitrides

Ye, J., Oechsner, H. 2006. On the nucleation of the cubic phase in boron nitride films. Thin Solid Films 514 138-144. [Pg.557]

Chem. Descrip. Boron nitride CAS 10043-11-5 EINECS/ELINCS 233-136-6 Uses Lubricant, filler for elec, insulating/thermally conductive materials, polymer matrixes, adhesives, pastes, potting compds., EP lubricants, refractories, refractory coatings, mold/die release, metal/ceramic and ceramic/matrix composites nucleating agent for foaming or solidification of plastics... [Pg.130]

Boron nitride was fonnd to produce epitaxial nucleation in PP. ... [Pg.11]

To generate foam, a gas (e.g., nitrogen, carbon dioxide, or chlorodifluoromethane) is continuously injected into the extmder, processing a fluoropolymer that has been compounded with a nucleating agent such as boron nitride." ... [Pg.108]

Boron nitride (0.5 wt%) was used as nucleating agent in melt-spun fiber from poly-3-hydroxybutyrate. The nucleating agent controlled and stabilized crystallization. Secondary crystallization was suppressed, which otherwise woirld have lead to brittleness and poor mechanical performance. ... [Pg.120]

Talc and mica are suggested for the use as nucleating agents in poly(ether sulfone). Also, boron nitride was used in PES as the nucleating agent. ... [Pg.153]

The nucleating agent for PET is selected from the group of talcrrm, boron nitride, alrrminrrm nitride, siUca, PIPE, a salt of organic compounds having acidic groups, pyra-zole, or their mixtures."... [Pg.154]

In the absence of nncleating agents, polyhydroxyalkanoates exhibit slow crystallization rates which make them less favorable for injection molding purposes. Various nucleating agents, such as orotic acid, a-cyclodextrin, boron nitride, talc, terbium oxide, lanthanum oxide, saccharin and phthalimide have been tested for enhancing the crystallization of PHA at elevated temperatures. ... [Pg.158]

Boron nitride is selected to improve moldabihty and decrease the molding cycle of POM." Nucleating agents for POM include titaniirm oxides and talc. ... [Pg.163]

The nucleating system for poly(p-phenylene sulfide) includes a combination of an inorganic crystalline compound and an aromatic amide oligomer. Because of the improved crystallization rate, the thermoplastic composition can be molded at lower temperatures to still achieve the same degree of crystallization. The inorgartic compound is boron nitride. Boron nitride used alone has also been proposed for PPS. ... [Pg.171]

The melt-spun poly(3-hydroxybutyrate) fibers contained boron nitride as nucleating agent. These fibers had longitudinally oriented lamellae rather than spheruhtic stmc-tures. Fibers contained domains of highly oriented molecules between crystallites. ... [Pg.195]
