For those reasons, different types of eoupling agents (Titanates, Isocyanates, etc) have been proposed [10-12], Among the coupling agents for polymer-natural fibers, a low molecular weight polypropylene (PP), modified with maleic anhydride (Epolene E-43) has improved fiber dispersion, and fiber-matrix interaction, promoting PP-cellulosic fiber compatibility [13-14]. [Pg.1866]

Organosilanes are the main group of coupling agents for glass fiber-reinforced polymers. They have been developed to couple virtually any polymer to the minerals that are used in reinforced composites f42J. [Pg.798]

Analog-to-glass fibers silanes are used as coupling agents for natural fiber polymer composites. For example, the treatment of wood fibers with product A-175 improves wood dimensional stability [53]. In contrast, a decrease of mechanical properties was observed for coir-UP composites after a fiber modification with di-chloromethylvinyl silane [54]. The treatment of mercer-... [Pg.798]

The subject of silane chemistry and its interaction with both glass surface and polymer resins have been studied extensively. Since the silane coupling agent for improving the bond quality has first appeared in the literature (Rochow, 1951), a wide variety of organofunctional silanes has been developed, prominently by Plueddemann and coworkers. An early compilation of this subject for epoxy and polyester matrix composites (Plueddemann et al., 1962, Clark and Plueddemann, 1963 Plueddemann, 1974), and more recent reviews on the use of silane agents and... [Pg.174]

The filler-elastomer chemical interactions take place through its surface functional groups and hydrogen atoms. Coupling agents improve polymer-filler adhesion. From the point of view of dynamic-mechanical properties for low strains, the filler-elastomer bonds have a positive effect in the reinforcement process. [Pg.126]

Aliphatic organofunctional silanes recommended as coupling agents for glass-reinforced polyesters, epoxies, or phenolics have heat stabilities of typical aliphatic organic chemicals and are not at all comparable to the methyl or phenyl silicones found in silicone polymers and resins. [Pg.108]

Coupling agents for more inert polymers like polyolefins are often acid-modified versions of the matrix polymer, with maleic acid grafted polypropylene as a prime example. [Pg.481]
