“Like many raw material suppliers, the wax and additives industry faced many challenges in 2010,” said Ron Levitt, regional sales leader, North America for Shamrock Technologies. “Raw material prices have increased across the board, and in some cases dramatically. We also experienced raw material shortages for some feedstocks. The good news was that business definitely picked up and improved over 2008/2009.
“We saw a general recovery,” Mr. Levitt added. “I believe this was mainly due to many customers having gone through the cycle of running inventories down to bare minimums and implementing ‘just in time’ strategies. We have adapted to this recovery by increasing inventories to meet our customers’ increased demand.”
Chris Halvorsen, global marketing manager for Hexion Specialty Chemicals, noted that Hexion has invested in its wax compounding and additives capability with modern manufacturing processes and efficiencies.
“We see more opportunity to combine our resins, varnishes and complete line of wax and additives to bring more value to our customers,” Mr. Halvorsen noted.
Bringing value to customers remains an important goal for manufacturers of waxes and additives, as their products play an important role in the success of any printing ink.
“Customers are looking for additives to help create differentiating properties in their ink platforms,” Mr. Halvorsen noted. “Performance additives can help minimize and simplify the overall ink formulations.”
“Ink manufacturers are looking for products that can maintain or improve current performance at lower usage levels or at a more economical level,” Mr. Levitt noted. “Our Product Technical Center is continually developing products to meet those customer needs. We also have requests to develop ‘green’ alternatives for petroleum based materials.”
However, the raw material situation remains a major problem throughout the ink supply chain. In particular, shortages in key feedstocks and other ingredients could become critical, and manufacturers of waxes and additives are working hard to secure their own supply chain.
“The biggest challenge is making sure there are enough raw materials for our customers,” Mr. Levitt said. “The recession has hit several upstream raw material suppliers and we have been fortunate to be diverse enough to maintain supply. Shortages in supply and increases in demand lead to higher prices. We have been working with our customers on efficiencies and more effective formulas to assist in keeping them competitive in their respective markets.”
“We have experienced significant raw material increases which are never easy to pass along,” Mr. Halvorsen said. “While it has been difficult to keep up with the increases, most important is maintaining reliable sources of critical raw materials.”
All in all, Mr. Levitt is cautiously optimistic about the coming year.
“We expect 2011 to continue to improve as 2010 has,” Mr. Levitt concluded. “Customer forecasts have been favorable going forward.”
