ADDITIVES | PVC
lating beyond additives supplied by Baerlocher to create a complete solution.” Baerolub and Baeropan additives can be used in rigid and semi-rigid PVC applications, such as profiles, siding (cladding), pipe and flooring. Baerolub internal lubricants lower the PVC’s melt viscosity by reducing friction between molecular chains, resulting in easier processing. Baerolub external lubricants are also available to control fusion properties and enhance metal release. Baeropan technologies deliver long-term stability and durabil- ity to withstand weathering and heat aging. Customers have the choice of custom one-packs

ogy for the new product’s rigid core. This custom stabiliser met the customer’s requirements for sustainability (no barium) and odour elimination (tin-free). “Baerlocher’s expertise and close collaboration enabled this start-up company to suc- cessfully enter the LVT market with a unique product that was the first of its kind fully-produced in North America,” the company says. Baerlocher also offers new Baeropan products for rigid-core wood/plastic composites (WPCs) and stone/plastic composites, also for LVTs. “Because PVC formulations can be very com-
plex, identifying the exact mix of additives for an application requires encyclopaedic knowledge and extensive experience,” says Gary Conroy, head of the North American Strategic Business Unit for Vinyl Additives at Baerlocher USA. “Baerlocher provides [this] through customised technologies and technical support [for] customers’ highly specific needs. We also provide advice on formu-
or off-the-shelf single-component grades. Baer- locher claims to have invented ready-made additive blends over 50 years ago; today, its one-packs are made to order. At the beginning of last year, Baerlocher said it
would expand production capacity by 50% for metal soaps at its operation in Cincinnati in the US by adding a third reactor for the production of types based on calcium, zinc, sodium and other metals. That reactor is now up and running. “We continue to see growth in the metal soap demand as was expected and we are now working on efficiencies to stay ahead of the growth for the coming years,” says Edward Hall, President and CEO of Baerlocher USA . “We will soon announce another large investment in blend technology to increase capacity on our Baeropol additive blend production with additional capabilities.”
