Product Description
PPO Series/Polyphenylene
PPO Chinese name is polyphenylene ether, it has the advantages of high rigidity, high heat resistance, flame retardant, high strength and excellent electrical properties, etc. PPO also has the advantages of wear-resistant, non-toxic, pollution-resistant, etc. PPO's dielectric constant and dielectric loss is one of the smallest varieties of engineering plastics, is virtually unaffected by temperature, humidity. Can be used in the field of low, medium and high frequency electric field (the smaller the dielectric constant, the better the insulation) PPO's load deflection temperature up to 190 ℃ or more, the deformation temperature -170 ℃. Polyphenylene ether, with excellent comprehensive performance, the most important feature is that under long-term load, has excellent dimensional stability and outstanding electrical insulation, the use of a wide range of temperatures, can be used for a long time in the range of -127 ~ 121 ℃. With excellent water resistance, steam resistance, products with high tensile strength and impact strength, creep resistance is also good, good abrasion resistance and electrical properties.
Modified polyphenylene ether (PPO) white material, through the modification, has an outstanding light-blocking effect, good ink adhesion, chemical resistance and molding of the product after the dimensional stability of the characteristics of the product, is widely used in a variety of digital tubes, dot matrix blocks, shaped displays and other LED products.
Our company produces PPO light-blocking materials commonly used specifications are: LD2100, LD2105, LD2110, LD2120, LD2130, LD2150, applicable to a variety of digital tubes, dot matrix blocks, shaped display and other LED products.
