| Hylar 5000是结晶型、高分子量、粉末状聚偏二氟乙烯，专用于溶剂型涂料，以获得更好的光泽。形成的机械强度高、韧度好的薄膜，能适应宽温度范围的应用。这些薄膜能耐受大多数环境，包括γ辐射。在紫外线辐射下基本呈透明状。 Hylar 5000涂料的耐候性使其具有出色的耐久性能。 Hylar 5000只能通过注明 Hylar 5000涂料成分的特定许可程序才可获得。正确配制的面漆含有足够的颜料，当膜厚达标称1密耳（ 0.001英寸）时，在紫外线照射下完全不透明。 安全性 hylar 5000在温度高达600°F （316℃ ）时依然保持稳定。当长期处于600 ° F（ 316 °C ）以上高温时，开始释出氟化氢（HF ），在温度高于700 °F （ 371 ° C）时，释出速度加快。 hylar 5000具有优良的阻燃性，但发生火灾时， HF和微量有潜在毒性的碳氟化合物开始形成。 HF具有腐蚀性，会导致接触烧伤，达到美国工业卫生会议（AC GIH）设置的阈值（TLV -TWA）3 ppm （2.5毫克/立方米）（1984） 。&& |
