Steel Plastic Compostie Belt 2021年4月19日 207

The steel-plastic composite belt is made of high-quality cold-rolled steel belt, and the composite film is made of EMAA material with excellent heat sealability. The surface of the composite belt is smooth and flat, without wrinkles, no oxidation spots, and
The volume is neat. The film is blue or natural. It is suitable for the manufacture of steel-plastic composite tapes for the shielding, moisture-proof and armoring layers of communication cables and optical cables.

steel-plastic composite belt

The main purpose

Telecommunications materials. It provides shielding, moisture-proof, chemical and armor protection layers for communication optical cables, communication cables, power cables, coaxial cables, and submarine optical cables.

Product thickness can be customized according to customer standards

The product is a single-sided and double-sided steel-plastic composite tape coated with copolymer EAA, the color is green.

The copolymer has good bonding properties to the steel strip substrate, and forms a strong bond with low-density, linear density, medium-density, high-density polyethylene and halogen-free polyolefin (HFPO) sheath resins, forming a “comprehensive” “Sheath” provides a reliable moisture barrier, armor, shielding and chemical protection layer for the cable core to prevent rodents from being injured and prolong its service life.

The steel base belt is made of plated low-carbon steel, which has good corrosion resistance, anti-extrusion, anti-distortion and easy processing properties.
