• intros：{"brand_intro":"特氟龙（Teflon）是科慕公司（Chemours）旗下的知名品牌，科慕于2015年从杜邦分拆独立。特氟龙品牌自1938年发现PTFE以来，已成为不粘涂层和密封材料的代名词。在工业密封领域，特氟龙膨体聚四氟乙烯密封带以\"高性价比、广泛适用\"著称。科慕继承了杜邦的品控体系，同时更注重成本优化。创始人Roy Plunkett偶然发现PTFE的故事广为流传，特氟龙品牌也因此带有\"意外创新\"的传奇色彩。目前特氟龙密封带在中国市场占有率极高，是中小型企业的首选。","product_intro":"特氟龙TF-1000膨体聚四氟乙烯密封带定位中端市场，兼顾性能与价格。核心卖点：通用性强，适用于水、油、气、弱酸碱介质；安装简单，可徒手缠绕；耐温-200°C至+260°C。相比GORE和杜邦，特氟龙在价格上优势明显（约68元/卷），适合预算有限的工厂。适用场景：普通法兰、管道螺纹、阀门填料函。竞品对比中，其蠕变率略高，但在常规工况下完全满足需求。","key_specs":{"材料":"膨体聚四氟乙烯（ePTFE）","温度范围":"-200°C 至 +260°C","耐压等级":"最高 100 bar（静态）","密度":"0.7-0.9 g/cm³","厚度":"1.0 mm / 1.5 mm / 2.0 mm","适用介质":"水、油、蒸汽、弱酸、弱碱"}}
