PE-g-MAH Low Smoke Halogen Free Flame Retardant Cable Material: W1L

Model No.: W1L

lntroduction:

Characteristic：W1L is a general-purpose LLDPE-g-MAH product with excellent comprehensive properties.

Characteristic：W1L is a general-purpose LLDPE-g-MAH product with excellent comprehensive properties. The terminal has the reactivity and strong polarity of maleic anhydride polar molecules. It can improve the interface affinity between polyolefin base material and inorganic substances such as mineral powder, inorganic flame retardant, wood powder, starch, etc. It can enhance the strength of composite materials, and is widely used in low-smoke halogen-free flame retardant cable materials.
