Alathon M5370RF



Alathon M5370RF is a natural, high density polyethylene copolymer resin selected by customers for high‐frequency coaxial cable primary insulation. Alathon M5370RF achieves low dissipation factors at high frequencies, and provides high impact strength, stress crack resistance, excellent color, and good processability.

For optimal performance in foamed insulation, Alathon M5370RF should be blended wiht Petrothene NA217080 and a nucleating package.

Alathon M5370RF meets the requirements of the following: ASTM D 1248, Type III, Class A, Category 3,Grade E11.
