Description and Application 产品描述和用途
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.

Attentions 注意事项：
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，材料一经开封，建议12小时之内用完。
2）Please ensure the screw, barrel, hopper are thoroughly cleaned before operation. Avoid bringing impurities while processing.
加工前确保螺杆、机筒、加料斗彻底清理干净，加工过程中严禁带入杂质。
3）If you need a faster extrusion. Please accelerate screw speed gradually to avoid inadequate plasticizing which may cause rough surface of the cables.
如果要快速挤出时，请慢慢逐渐加快螺杆转速，以免塑化不良，电缆表面毛糙。
