Halogen-free low-smoke flame-retardant polyolefin cable sheath material
l Feature and Usage
l Characteristics: good flame-retardant property, easy control for process temperature as well as  good stretching, mechanical and anti-cracking performance;
l Purpose: used for sheath layer of flame-retardant cable or large-scale facilities such as high-rise buildings, public places and underground tunnels.


Packaging, transportation and storage
Packaging: aluminum-plastic composite damp-proof package: 25kg/ bag;

Transportation: Handle with care to avoid breaking the bag;

Storage: the moisture absorption property of product is strong, the product shall be used immediately after opening the packaging, and the pre-drying is not necessary; If the product is not used completely, it is required to be sealed, and the  time interval for subsequent use should not be too long; otherwise, the extrusion appearance will be affected.
 

Executive Standard: GB/ T32129-2015.
