不含卤素、阻燃、热塑性护套材料 UNIGARD™ RE DFDC-1638 Black 是一种不含卤素、阻燃等级高、热塑性的、低烟、低腐蚀性和低毒性材料。这种材料应用于通用的电联护套领域。使用该产品制造的护套可以轻松地通过IEEE-383/UL-1685 (有限产烟测试) 垂直托架电缆燃烧测试。当然,电缆的结构在阻燃性能中起着重要的作用。采用这种材料作为护套的电缆的最高工作温度可高达90°C。 该产品可以替代PVC、低烟PVC和含卤素橡胶作为护套材料,它具有优异的防火安全性(低烟、低腐蚀性和低毒性) 和良好的性能平衡。该产品可以满足或者超出很多业界对护套材料的规格要求:UL-1277 托架电缆,UL Subject 444 要求的通用用途通信电缆、轨道交通应用和多种国际应用领域。 作为一种不含卤素的阻燃护套材料, DFDC-1638 Black 也可用于替代普通的非卤素护套产品。与现有的非卤素护套产品相比,这种产品的挤出温度更高 (可高达392°F [200°C]), 而且可以使用常用的单螺线计量PE螺杆进行挤出加工。 特性 UNIGARD RE DFDC-1638 Black 具有以下特性: 阻燃性能高(IEEE 383 燃烧测试等级) 环保 (无铅、不含卤素、无硫/无锑) 低烟、腐蚀性低以及低毒性 挤出容易,无需特殊螺杆 优异的耐切通性能、耐挤压性能和耐磨性能 耐紫外线性能、防潮性能和防水性能良好 在韧性和柔软性之间具有良好的平衡性 耐电痕性能和耐蚀性能 UNIGARD™ RE DFDC-1638 Black is a non-halogen, highly flame retardant, thermoplastic, low smoke, low corrosive, and low toxic compound. It is designed for general purpose cable jacket applications. Used as jacket, it easily passes the IEEE-383/UL-1685 (Limited Smoke Test) vertical tray cable burn tests. Cable construction, of course, plays an important role in flame performance. It can be used as a jacket on cables operating at up to 90°C. This compound can replace PVC, low smoke PVC, and halogenated rubbers as a jacket with excellent fire safety (low smoke, low corrosivity, and low toxicity) and good property balance. This compound meets or exceeds many industry jacket specifications: UL-1277 Tray Cable, UL Subject 444 for general purpose communication cable, mass transit applications, and several international applications. As a non-halogen, flame retardant jacket, DFDC-1638 Black is also designed to replace the conventional non-halogen jacket products. This compound has much better process-ability than current non-halogen jacket products. It can sustain a higher extrusion temperature (up to 392°F [200°C]), and can be extruded in the typical single-flight metering PE screws. Features UNIGARD RE DFDC-1638 Black provides the following features: Highly flame retardant (IEEE 383 flame test rating) Environmentally friendly (lead-free, halogen-free, sulfur/antimony-free) Low smoke, low corrosivity, and low toxicity Ease of extrusion and no special screw required Excellent cut-through, crush, and abrasion resistance Good UV, moisture and fluid resistance Good balance of toughness and flexibility Track and erosion resistant |
