pps pps little knowledge of the dielectric constant of the same small, relatively low dielectric loss, surface resistivity and volume changes in frequency, temperature, humidity insensitive, it can be said pps is an excellent electrical insulating material, its resistance arcing time is longer, chemical stability pps quite good, except by strong oxidizing acids, such as concentrated sulfuric acid, concentrated nitric acid and aqua regia erosion outside, pps plastic mold, it is not the majority of acid and salt erosion, have close to the chemical stability of PTFE. At 175 degrees Celsius below any known insoluble in organic solvents, cracking phenomenon does not occur when the plastic parts in contact with the common organic solvents pps. Dongguan Yu Sheng Plastic Chemical Co., Ltd. welcome to inquire, we provide professional services. The main performance of the PPS: ◆ [heat resistance] PPS has excellent heat resistance, and its melting point exceeds 280 ℃, heat distortion temperature under load 1.8MPa above 260 ℃, long-term use temperature of 220-240 ℃. ◆ [flame retardant] PPS resin itself during the hair has good flame resistance, without adding flame retardant can achieve UL94-0 level and 5-V level (non-drip), pps plastic grades, and the combustion low smoke. ◆ [mechanical properties] mechanical strength of pure PPS resin is not high, after the glass fiber or carbon fiber-reinforced or mineral-filled classics, doubling its strength and rigidity and has excellent resistance to creep and fatigue resistance. High surface hardness, Rockwell hardness> 100HR, tensile strength> 170MPa, pps plastic prices, flexural strength> 220MPa, notched impact strength> 16MPa, flexural modulus of> 3.5 × 104, ◆ [Chemical resistance] PPS resistance to chemicals Excellent performance, Nanxiong pps plastic, second only to PTFE, below 200 ℃ insoluble in any organic solvent, in addition to strong oxidizing acids, inorganic acids, bases and salts resistance strong. And a variety of radiation is also very stable, Dongguan City, Yu Sheng Plastic Chemical Co., Ltd. sincerely hope to cooperate with domestic and foreign manufacturers! We will be a fair price, superior quality, fast service and your common development! pps plastic grades, Yu-sheng plastics affordable (certified), Nanxiong pps plastic provided by the Dongguan City, Yu Sheng Plastic Chemical Co., Dongguan Yu Sheng Plastic Chemical Co., Ltd. (www.yushengpc.com) (www.yushengpc.com) is Dongguan, a leader in engineering plastics for many years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
