XAREC Syndiotactic Polystyrene XAREC is the world's first syndiotactic polystyrene (SPS) resin. Idemitsu created this unique SPS product at our central research laboratories by combining a metallocene catalyst with a styrene monomer. The metallocene catalyst gives flexibility to the structure of the crystallized polystyrene SPS, allowing a variety of benzene ring arrangements. In addition, we have applied our advanced alloying and composite technology to greatly expand the commercial potential of XAREC as an engineering plastic. XAREC is not only a superior engineering plastic, but is also environmentally friendly. This combination makes it the first choice for many of our customers. . Resistance to hydrolysis Compared to polyester- and polyamide-based resins, XAREC offers a superior hydrolysis resistance, comparable to polyphenylene sulfide. Chemical resistance XAREC is highly resistant to corrosion by various acids and alkalis, and can withstand automobile oils and antifreeze. Low specific gravity With one of the lowest specific gravities of all engineering plastics on the market, XAREC reduces the weight and cost of parts. Heat resistance With a long-term heat resistance of 130°C, a heat distortion temperature of 250°C and a melting point of 270°C, XAREC can be used for wave and reflow soldering. XAREC is also moisture resistant, and useful for surface mount chip parts and connectors. Electrical properties XAREC's electrical properties, including its dissipation factor and dielectric constant, are similar to those of fluororesins. Because it is electrically stable over a wide range of frequencies and temperatures, XAREC is suitable for high-frequency components. Dimensional stability Because the flow and transversal direction of the molten resin changes little during mold shrinkage, XAREC offers good dimensional performance when compared to other glass-fiber-reinforced crystalline resins. Processability XAREC can easily be molded on any standard specification injection molding machine. It possesses high flow properties, close to those of liquid crystal plastic, and degradation due to heating is minimal. It is also ground easily, making XAREC easy to recycle.

Polystyrene
 
28:11
Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic aromatic polymer made from the monomer styrene, a liquid petrochemical. Polystyrene can be rigid or foamed. General purpose polystyrene is clear, hard and brittle. It is a very inexpensive resin per unit weight. It is a rather poor barrier to oxygen and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several billion kilograms per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and CD and DVD cases), containers (such as "clamshells"), lids, bottles, trays, tumblers, and disposable cutlery. Polystyrene is used to make napalm-B, where it makes up about 46% of the formulation. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behavior is exploited for extrusion, and also for molding and vacuum forming, since it can be cast into molds with fine detail. This video is targeted to blind users.

Polypropylene

Polypropylene Polypropylene enjoys wide application in technology engineering. This is a synthetic thermoplastic non-polar polymer classified as polyolefin. It is the product of propylene polymerization. Polypropylene is a solid white material with the chemical formula of C3H6. Propylene polymerization results in polypropylene linear molecule whose building blocks include -CH2-CH- bond with CH3 methyl side group. According to the methyl group position in the polymer chain, polypropylenes fall under: atactic polypropylenes whose methyl groups are located randomly at both sides of the polymer chain; syndiotactic polypropylenes whose groups have alternate positions along the chain; and isotactic polypropylenes whose all methyl groups are located on the same side of the polymer chain. Such polypropylenes are 50% more rigid and 25% harder than atactic polypropylenes. Polypropylene's physical, chemical, mechanical and electric properties greatly depend on the macromolecular structure. Polypropylene is marked as double-P both in Cyrillic and Latin alphabet. Polypropylene is a plastic material demonstrating high impact and cross-breaking strength. It is wear-resistant and has good electric insulation properties within wide temperature ranges. It is also chemically stable and water-resistant. Polypropylene products are manufactured based on all thermoplastic material processing technologies. Polypropylene finds wide application in the industry. It is used to produce packaging and car components, case works and pipelines. It is also widely used in electronic engineering. Polypropylene is used to produce packages to a lesser extent, however, than polystyrene and ABS resins. But unlike the latter, polypropylene packages can stand load impacts and are more resistant to abrasion damages. That's why they can be used under unfavorable environment. Polypropylene is used as a dielectric material in capacitors, for instance, in Russian K78-2 capacitors or as electric insulation. Recently, polypropylene has earned a great deal of popularity as internal insulators in high-voltage cables and has become a good substitute for polyethylene.
