performance while operators of larger extruders need to increase output. Maintaining and improv- ing performance in oil and water environments and enhancing the hydrophobicity of compound formulations are also among the top priorities. High loading levels of hydroxide-type flame
retardants are important to achieve better perfor- mance. However, such high loading levels typically compromise mechanical and electrical perfor- mance. There is a need, therefore, for additives that can improve loading levels without compromising performance. Evonik has developed a number of organo-modified siloxane additives – including its Tegomer V-Si 4042 and Tegopren 6879 grades – that make it possible to increase the maximum loading levels of hydroxide-type flame retardants while achieving homogenous dispersion in the polymer matrix so that mechanical properties of the wire or cable compound are not negatively affected and good processability is maintained. Evonik’s organo-modifier siloxanes (OMS) are available in liquid and solid form. “We are also introducing a dry crosslinker in peroxide and e-beam crosslinking compound formulations to improve crosslinking efficiency,” says Offenbach.
“These additives are based on silane, trialkyl and triallyl functionality. We also have organic porous carrier technology – Accurel XP – based on EVA, HDPE and LLDPE, which allow customers to transfer liquid additives into solid masterbatches for convenient dosage on all extrusion lines. In addition, we have developed Accurel XP for PA6 and PA12 polymer compounds for demanding cable applications, such as tunnel operations.” Future wire and cable developments at Evonik will include the introduction of a dry silane series of additives. The dry silane products will offer easier and more precise dosage than standard liquid silanes while, due to their solid nature, help keep the production site cleaner.
Halogen-free According to Tolsa, significant growth continues in the area of halogen-free cables due to the emer- gence of new and tougher regulations and growing demand for high-performance cables. The company’s Adins additive products can help meet these requirements, according to its Special Additives Business Unit team. Adins additives are used mainly in medium and
