A new flexible polyurea resin, Chemthane 7070, is designed for manufacturing artificial tree bark. Made and marketed by Chemline, Chemthane 7070 is a spray-in-mold elastomeric polyurea with hardness formulations ranging from 75-85 Shore D. It is a 1:1 mix of solids that contains no solvents or styrene.
“If you have an application where real trees won’t survive, they weigh too much, or simply won’t fit through the door, Chemthane 7070 offers an attractive alternative,” said John Henningsen, Chemline’s director of marketing and sales. Molds for processing the material are made from real trees. The molding process is said to capture even the slightest surface details of the real tree bark. Bark from 3-12 mm thick can be formed.—[email protected]
