Grade Origin: The Standardized Mark of Global Giants<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The nylon grade system was primarily established and promoted by European, American, and Japanese chemical giants, forming a de facto global industry language. For example, DuPont, the inventor of PA66, uses the grade \u201cPA66-1032L\u201d where the \u201c1032\u201d indicates the specific viscosity and additive system; the \u201cL\u201d stands for light resistance and stability. BASF\u2019s PA6-B30S, for example, has a glass fiber reinforcement designation. \u201cB\u201d indicates glass fiber reinforcement, \u201c30\u201d represents 30% glass fiber content, and \u201cS\u201d indicates thermal stability. This naming is not arbitrary; it strictly reflects the material\u2019s key performance parameters (viscosity, reinforcement, additives, thermal and light stability, etc.), providing global design engineers with an unambiguous and precise material selection guide. The International Organization for Standardization (ISO) is also committed to harmonizing material classification and nomenclature to promote efficient collaboration across the global supply chain.<\/p>\n<h3 id=\"-ii-pa12-the-precision-choice-for-flexibility-and-chemical-resistance-\"><span class=\"ez-toc-section\" id=\"II_PA12_The_Precision_Choice_for_Flexibility_and_Chemical_Resistance\"><\/span>II. <a href=\"https:\/\/nylon-granules.com\/ja\/products\/nylon-12\/\">PA12<\/a>: The Precision Choice for Flexibility and Chemical Resistance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>PA12 (such as\u00a0DSM\u2019s\u00a0<code>PA12-TR55LX<\/code>\u00a0and\u00a0Evonik\u2019s\u00a0<code>PA12-PDX-I-99038<\/code>) offers unique advantages due to its long carbon chain structure:<\/p>\n<ul>\n<li>Excellent Flexibility and Low-Temperature Toughness: Its flexural modulus is significantly lower than that of PA6\/PA66, making it suitable for applications requiring repeated bending, such as\u00a0automotive fuel lines\u00a0(resistant to ethanol gasoline penetration) and\u00a0industrial pneumatic tubing.<\/li>\n<li>Extremely Low Moisture Absorption: Its dimensional stability far exceeds that of short-chain nylons, making it the preferred choice for\u00a0precision gears and high-end sports equipment components.<\/li>\n<li>Biocompatibility Certification: Some medical-grade grades are ISO 10993 certified and are widely used in\u00a0interventional catheters and drug delivery devices.<\/li>\n<\/ul>\n<h3 id=\"-iii-pa46-a-fortress-of-performance-in-high-temperature-environments-\"><span class=\"ez-toc-section\" id=\"III_PA46_A_Fortress_of_Performance_in_High-Temperature_Environments\"><\/span>III.
