 |
Elvax resins are a family of ethylene/vinyl acetate copolymers that are useful in many wire and cable applications because of their excellent mechanical, thermal and low-smoke properties.
The grades of Elvax recommended for wire and cable range in vinyl acetate content from 9-40 percent and in melt index from 0.3-52.
Both Elvax 40L-03 and 40L-08 contain 40 percent vinyl acetate.
The nominal melt index of Elvax 40L-03 is 3.0 and 40L-08 is 6.0, which is appropriate for convenient compounding and extrusion.
The melt index is consistent because resin molecular weight distribution is controlled to within a relatively narrow range.
The molecular weight is high for this family of copolymers, so finished products will be relatively resistant to mechanical damage and elevated temperatures.
Compared with other ethylene/vinyl acetate copolymers, Elvax 40L-03 and 40L-08 contain extremely low amounts of gel, or high-molecular-weight polymer, that can cause undesirable characteristics in finished products. |
