Black Wire Concentrate Won't Cause Pinholes.A new polyethylene-based black color concentrate for extrusion of fiber-optic and coaxial co·ax·i·al adj. Having or mounted on a common axis. coaxial Adjective 1. Electronics (of a cable) transmitting by means of two concentric conductors separated by an insulator power and communications cable Communications cable A cable that transmits information signals between geographically separated points. The heart of a communications cable is the transmission medium, which may be optical fibers, coaxial conductors, or twisted wire pairs. jacketing is said to be free of agglomerations that can cause pinholes and uneven jacketing surface. Petrothene PM 92973 from Equistar Chemicals, LP, Houston, contains 40% carbon black and a thermal antioxidant antioxidant, substance that prevents or slows the breakdown of another substance by oxygen. Synthetic and natural antioxidants are used to slow the deterioration of gasoline and rubber, and such antioxidants as vitamin C (ascorbic acid), butylated hydroxytoluene . It can be used with all types of PE, as well as PP. Compounds using the new concentrate reportedly show reduced shrinkage Shrinkage The amount by which inventory on hand is shorter than the amount of inventory recorded. Notes: The missing inventory could be due to theft, damage, or book keeping errors. and are less susceptible to degradation and oxidation than other PE-based jacketing compounds. |
