| SI-LINK™ DFDB-5445 BK是一种符合RoHS（有害物质还原）的阻燃母粒，设计用于与Si-Link DFDA-5451 NT聚乙烯和催化剂母粒Si-Link DFDB-5480 NT聚乙烯一起使用，以形成阻燃Si-Link聚乙烯绝缘系统。该系统由UL发布为DFDB-5445 BK，可湿固化。系统的比重为1.02。建议用于低压电力电缆和工业电缆应用。它的设计是为了在较大的电缆上通过UL-44水平燃烧试验。SI-LINK™ DFDB-5445 BK是一种填充率很高的黑色阻燃母料，计划在35%的浓度下使用，以及60%的Si-Link聚乙烯DFDA-5451 NT和5%的Si-Link DFDB-5480 NT催化剂母料，尺寸大于等于2 AWG导线。在该浓度下，满足UL-44、UL-854规定的xhh、xhw、xhw-2、rhh、rhw、rhw-2、sis、使用和使用-2电缆的要求。.SI-LINK™ DFDB-5445 BK提供了定制配方的灵活性，以满足一系列电缆尺寸的水平燃烧要求。在浓度增加的情况下，SI-LINK™ DFDB-5445 BK已被证明能够提供较小尺寸的水平燃烧试验依从性。配方的经济性可根据生产的电缆尺寸和选择的UL提交尺寸针对特定应用进行优化。加工条件、固化度和导体类型等因素会影响结果，因此电缆制造商必须为其应用确定最佳配方。如有要求，可提供建议。规格：SI-LINK™ DFDB-5445 BK系统由美国保险商实验室（UL）对XHH、XHW、XHW-2、RHH、RHW、RHW-2、SIS、在2号或更大规格的AWG上使用和使用-2进行了编号。它适用于CSA RW-90和RWU-90应用。 SI-LINK™ DFDB-5445 BK is a RoHS (Reduction of Hazardous Substances)-compliant flame retardant masterbatch designed to be used in conjunction with SI-LINK™ DFDA-5451 NT Polyethylene and the catalyst masterbatch SI-LINK™ DFDB-5480 NT Polyethylene to form a flame retardant SI-LINK polyethylene insulation system. This system is bulletinized by UL as DFDB-5445 BK and is moisture curable. The specific gravity of the system is 1.02. It is recommended for use in low voltage power cable and industrial cable applications. It is formulated to pass the UL-44 horizontal burn test on larger cables. SI-LINK™ DFDB-5445 BK, a highly filled black flame retardant master-batch, is intended to be used at a 35% concentration along with 60% SI-LINK Polyethylene DFDA-5451 NT and 5% SI-LINK DFDB-5480 NT Catalyst Master-batch on size #2 AWG conductors and larger. At this concentration the requirements for XHH, XHHW, XHHW-2, RHH, RHW, RHW-2, SIS, USE and USE-2 cables as defined by UL-44, UL-854 are satisfied. . SI-LINK™ DFDB-5445 BK offers flexibility in tailoring the formulation to meet the horizontal burn requirement on a range of cable sizes. At increased concentrations, SI-LINK™ DFDB-5445 BK has been shown to provide horizontal burn test compliance in smaller sizes. The economics of the formulation may be optimized for a particular application depending on the cable sizes produced and the UL submittal sizes selected. Such factors as processing conditions, degree of cure and type of conductor can affect the results, so cable manufacturers must determine the optimal formulations for their applications. Recommendations are available upon request. SPECIFICATIONS The SI-LINK™ DFDB-5445 BK system is bulletinized by UL for XHH, XHHW, XHHW-2, RHH, RHW, RHW-2, SIS, USE and USE-2 on sizes 2 AWG and larger. It is suitable for CSA RW-90, and RWU-90 applications. |
