tabindex=\"0\"><strong><strong><strong>Material Introduction<\/strong><\/strong><\/strong><\/div><div class=\"wp-block-themeisle-blocks-tabs-item__content\">\n<p class=\"wp-block-paragraph\">Polyphenylene Sulfide (PPS) is a high-performance thermoplastic engineering plastic renowned for its excellent high-temperature resistance, chemical stability, and mechanical properties. PPS is polymerized from p-dichlorobenzene and sodium sulfide in a polar solvent. Its molecular structure consists of alternating benzene rings and sulfur atoms, giving it a regular structure with high crystallinity. The benzene rings provide rigidity and heat resistance, while the thioether bonds impart flexibility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PPS has a melting point of approximately 280\u00b0C. The continuous service temperature (when reinforced) can exceed 200\u00b0C, with the highest continuous temperature reaching up to 260\u00b0C, and its thermal decomposition temperature is as high as 522\u00b0C. It exhibits outstanding thermal-oxidative stability, resisting attack by strong acids and bases, and is virtually unaffected by any organic solvents. In addition, PPS is inherently flame retardant with a UL94 V-0 rating, has stable electrical insulation, low water absorption, high mechanical strength, and excellent wear resistance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PPS can be processed through various methods such as injection molding, extrusion molding, blow molding, and compression molding. It can also be modified by blending, reinforcement, and alloying to improve its physical and mechanical properties. Adding materials like glass fiber, carbon fiber, minerals, and elastomers significantly enhances PPS's tensile strength, flexural modulus, notched impact strength, and other properties.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div id=\"wp-block-themeisle-blocks-advanced-columns-b05bd3ef\" class=\"wp-block-themeisle-blocks-advanced-columns alignwide has-1-columns has-desktop-equal-layout has-tablet-equal-layout has-mobile-equal-layout has-vertical-unset\"><div class=\"wp-block-themeisle-blocks-advanced-columns-overlay\"><\/div><div class=\"innerblocks-wrap\">\n<div id=\"wp-block-themeisle-blocks-advanced-column-aad48113\" class=\"wp-block-themeisle-blocks-advanced-column\">\n<div id=\"wp-block-themeisle-blocks-tabs-df28e45a\" class=\"wp-block-themeisle-blocks-tabs is-style-border\"><div class=\"wp-block-themeisle-blocks-tabs__content\">\n<div data-title=\"&lt;strong&gt;&lt;strong&gt;&lt;strong&gt;Application Industry&lt;\/strong&gt;&lt;\/strong&gt;&lt;\/strong&gt;\" class=\"wp-block-themeisle-blocks-tabs-item\"><div class=\"wp-block-themeisle-blocks-tabs-item__header\" tabindex=\"0\"><strong><strong><strong>Application Industry<\/strong><\/strong><\/strong><\/div><div class=\"wp-block-themeisle-blocks-tabs-item__content\">\n<p class=\"wp-block-paragraph\">PPS sealing rings are widely used in multiple industries due to their excellent high-temperature resistance, chemical corrosion resistance, and wear resistance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\">Automotive Industry<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">PPS sealing rings can withstand the high temperatures and complex chemical environments in engine compartments.
