Glass libers

Improvement in flexural strength due to silane treatments in glass liber thermoplastic matrix composites"... 

Glass libers as used in lightwave communications are described under Optical Fiber Systems. See also Alphabetical Index. 

VE resins are more expensive than UP resins. They are used as matrices for glass-liber composites when a better corrosion resistance is needed. 

The inclusion of the relatively large chlorine into the polymeric chain reduces the tendency to crystallize. Commercially available grades include a homopolymer, which is mainly used for special applications, and copolymers with small amounts (less than 5%) of vinylidene fluoride.84 The products are supplied as powder, pellets, pellets containing 15% glass liber, and dispersions. Low-molecular-weight polymer is available as oil or grease. The oil is used to plasticize PCTFE.85... 

The worldwide production of textile glass libers was ca. 2 10 t/a in 1993. An increase to 3 10 t/a is expected by the end of the twentieth century. The USA, Western Europe and Japan together produce about thereol. with an increasing share being produced in Eastern Europe and in Asia. The USA production in 1993 was 794 10 t/a with a value of 2.523 million US. The current Europetin market for glass-reinforced polymers is 1.3 10 t/a, with 196 10 t/a being produced in the Federal Republic of Germany. 

The manufacture of textile glass libers is illustrated below by that for E-fibers.

While mechanical conditioning is most commonly associated with elastomers, thermoplastics and composites are not excluded. Reference [36] for example looks at the influence of meehanical conditioning on the viscoelastic behavior of glass-liber-reinforccd epoxy resins. 

Torsional braid analysis (TBA) The damping behavior of the torsion of a glass liber probe impregnated with the resin is characteristic for the increase of stiffness. 169,171,378... 

POCs and nanocomposites have many applications in our daily life including different consumer products such as park benches and tables, home furniture, musical instraments, playground equipment, cooking ware, bathroom materials, trash bins, landscape timbers, railroad ties, toys, and home appliances. Natural fillers such as wood POCs and synthetic fillers such as glass liber POCs are the two most common composites of the ciurent plastic industry [14, 15]. These polyolefin and filler composites possess many advantages such as ... 

The situation is different with thermo sets and elastomers. They are usually introduced to the machine in the form of strips (elastomers) or liquids (silicone rubber). Thermosets are supplied as powders or liquids. Thermosets reinforced by long glass libers are sometimes loaded into the machine as sauerkraut . 

With regard to PET fraction, the potential applications are strongly dependent on its purity (as discussed earlier). Applications like films, fibers, or straps are not recommended when a high concentration of impurities are present. In this case, the PET fraction can be employed for structural applications as an engineering polymer with the addition of other components like glass libers, impact modifiers, and/or nucleating systems. However, reuse of the PET fraction impKes that the amount of residual PVC must be kept below 50 ppm to avoid undesirable polymer degradation that results in poor surface appearance and loss of mechanical properties of the manufactured products.
