The performance advantages of polystyrene tarpaulin

by:LINYANG     2023-03-09
There are several kinds of tarpaulins on the plastic tarpaulin wholesale market, polystyrene tarpaulin is one of the common types, according to the parties concerned, the main performance advantages of using this tarpaulin are: 1. Chemical properties: excellent corrosion resistance , solvent resistance and oxidation resistance. Polystyrene is resistant to various alkalis, salts and aqueous solutions, to lower alcohols and certain acids such as sulfuric acid, phosphoric acid, boric acid, 10 to 30 percent hydrochloric acid and 1 to 25 percent acetic acid . Formic acid at 1 to 90 percent by mass is also stable, but concentrated nitric acid and other oxidizing agents can destroy it. 2. Optical properties: excellent optical properties, light transmittance from 88% to 92%, refractive index from 1.59 to 1.60, can transmit all wavelengths of visible light, plastic transparent materials second only to acrylic, such as plexiglass polymer. 3. Electrical properties: Polystyrene has excellent electrical properties, low dielectric loss tangent, and is not affected by changes in frequency, ambient temperature and humidity, and is an excellent electrical insulating material. 4. Thermal properties: The characteristic temperature of polystyrene is as follows: the brittleness temperature is about minus 30 degrees Celsius, the glass transition temperature is 80 degrees Celsius to 105 degrees Celsius, the melting temperature is 140 degrees Celsius to 180 degrees Celsius, and the decomposition temperature is above 300 degrees Celsius. 5. Mechanical properties: I believe that polystyrene molecules and their aggregated structures are hard and brittle materials that will undergo brittle fracture under stress.
