Artificial tree bark

SpecialChem / Aug 20, 2009

The American company Chemline that is specialized in polyurethane, polyurea and epoxy coatings as well as specialty foams has designed a new technology that allows to manufacture artificial tree bark by using a flexible polyurea resin. This artificial bark can be from 3 to 12 mm thick. In fact Chemline has developed a special spray-in-mold elastomeric polyurea with hardness formulations ranging from 75 to 85 Shore D and that is available under the trade name Chemthaneā„¢ 7070. This new resin that does not contain any solvent or styrene has to be injected into a special mold made from real trees. As a result the molding process permits to capture even the slightest surface details of the real tree.
