Description and Application 產品描述和用途
FJUV125, FHUV125are irradiation cross-linkable low-smoke halogen-free flame-retardant insulation and jacketing compounds. They have good mechanical property, electrical property, flame retardant property and processability, especially for anti-ozone, anti-UV and high-temperature resistant properties. It is low smoke, halogen free, flame retardant, and especially suitable for the insulation and jacketing of solar PV cables which have strict aging property requirements. Those cables can pass TUV identification. They also can be used for other cables which have long service life requirements.
FJUV125，FHUV125是輻照交聯型低煙無鹵阻燃絕緣料和護套料，其具有優良的物理機械性能，電性能，阻燃性能以及加工性能，更為突出的是其具有卓越的抗臭氧、抗紫外線，耐高溫等特性，產品低煙，無鹵，阻燃，特別適用于對老化條件要求較高的太陽能光伏電纜的絕緣，護套上，也可用于其它有較長使用壽命要求的電纜上，用該產品制成的光伏電纜可以過TUV認證。

Attentions 注意事項：
1）The compound should be dried before using if the package is broken. Once package is open, recommend to run out within 12 hours.
原料破包需烘干后才能使用，材料一經開封，建議12小時之內用完。
2）Please ensure the screw, barrel, hopper are thoroughly cleaned before operation. Avoid bringing impurities while processing.
加工前確保螺桿、機筒、加料斗徹底清理干凈，加工過程中嚴禁帶入雜質。
3）If you need a faster extrusion. Please accelerate screw speed gradually to avoid inadequate plasticizing which may cause rough surface of the cables.
如果要快速擠出時，請慢慢逐漸加快螺桿轉速，以免塑化不良，電纜表面毛糙。
