PS(EPS) TAITA Taitacell EPS 351SUse performancePolystyrene (English: Polystyrene, referred to as PS) as a colorless transparent thermoplastic plastic, is from a styrene monomer by free radical condensation reaction of synthetic polymers, because they have a higher than 100 degrees Celsius glass transition temperature, so is often used to make disposable containers that need to withstand the water temperature or disposable foam lunch boxes. Polystyrene is usually a head-tail structure, and the main chain is a saturated carbon chain, the side group is conjugated to a benzene ring, the molecular structure is not structured, increases the rigidity of the molecule, and the PS to a non-crystalline linear polymer. Benzene rings exist, PS having a high Tg (80 to 82 ° C), at room temperature is transparent and hard, and easy to cause stress cracking due to the rigidity of the molecular chain. Polystyrene colorless and transparent, and can be freely colored, relative density also after the PP, PE, having excellent electrical properties, especially high-frequency characteristics, and the second F-4, PPO. Further, in the light stability after the methacrylic resin, but the ability of the anti-radiation is the strongest of all plastics. The most important features of polystyrene is a very good thermal stability and fluidity when melted, so easy molding, especially injection molding easy, suitable for mass production. Mold shrinkage, dimensional stability of molded products, or. The maximum operating temperature of the thermal performance of 60 ~ 80 ℃. When heated to above Tg, the PS into a high elastic state, and this state is maintained in a within a wide range, which makes them facilitate thermoforming. PS thermal deformation temperature of 70 to 80 ° C, the embrittlement temperature of -30 ° C, and the intense degradation of the PS at high vacuum and 330 to 380 ° C. The molecular weight of the mechanical properties of the PS is too high, processing difficulties, and so normally the molecular weight of polystyrene of 5 to 20 million. The mechanical properties of the PS, with increasing temperature, rigidity (modulus of elasticity, tensile strength, impact strength decreased, and the large elongation at break. PS good transparency, light transmission rate of 88 to 92%, second only acrylic polymer, the refractive index of 1.59 to 1.60. therefore can be used as optical components, but it is subject to the action of sunlight, prone to yellowing and haze. PS main drawback is brittle and low heat resistance, for PS modification, such as rubber modified high impact PS (HIPS); MMA-butadiene - styrene (MBS); A (acrylonitrile) (butadiene) s, the most widely used in the industrial application is the ABS the plastic insulation resistance, lasting insulation: extruded plate, the thermal conductivity of 0.028w/mk, has a high thermal resistance, low linear expansion characteristics of its thermal conductivity is much lower than other insulation materials such as: EPS board, polyurethane foam, insulation mortar, cement perlite. stable chemical and physical structure of the material has to ensure that the insulation properties of this material, durable and stable. superior moisture resistance water resistant water resistant, moisture : extruded plate with tightly closed cell structure. the polystyrene molecular structure itself does not absorb water, the front and back of the plate there is no gap, therefore, extremely low water absorption, excellent moisture-proof and anti-permeability high compressive strength extruded plate and intramural closely linked foam structure seamless, so its high compressive strength, even if the long blisters remained unchanged. therefore used as a parking platform, airport runways, highways and other areas can be subject to good impact resistance, durability, corrosion resistant durable: after a few years of use of general rigid foam insulation material is easy to produce aging the attendant result absorbent performance degradation caused by extruded plate has excellent anti-corrosion, anti-aging , thermal insulation, high water vapor pressure, to maintain its excellent performance, service life of 30-40 years. physical properties of light hardness: lightweight extruded plate completely closed-cell foam structure formation, and uniform does not affect the structure of the capacity of cellular structure caused by the high hard, but unlike polyurethane foam, phenolic foam as crisp, unbreakable, not only carrying a portable, easy to cut, used as roof insulation environmentally friendly high quality environment-friendly: extruded board will not decompose and mildew, no harmful substances volatile, chemically stable in the production process at the same time, the use of environment-friendly raw materials, does not produce harmful gases, no wastewater generated by the formation of solid scraps, recyclable processing re-use, high-quality environment-friendly products.
