New Spray-in-Mould Polyurea Replicates Tree Bark

24 January 2009

Chemline has launched a flexible polyurea resin material specifically designed for manufacturing artificial tree bark.

This new product, Chemthane 7070, gives fabricators, contractors and building owners an alternative means of decorating open areas with high realistic artificial trees. This information is according to John Henningsen, spokesperson for the manufacturer.

Chemthane 7070 is a spray-in-mold elastomeric polyurea with high elongation and hardness formulations ranging from 75-85 Shore D. This 1:1 mix, 100% solids product is environmentally friendly and it does not contain 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,"" Mr. Henningsen added.

Chemthane 7070 is produced using moulds taken directly off real trees. Using various molding compounds you can quickly replicate any species of tree. This patented process uses nature to do most of the detail work. The moulding process captures even the slightest surface details of the real tree bark.

The artificial bark is a spray-in-mould, lightweight, flexible polymer. The liquid resin is used by licensed fabricators to produce large sheets of bark that are 3 -12 mm thick. According to information supplied by the manufacturer, Chemline offers as an easy-to-use, extremely realistic way of producing durable artificial tree bark to decorate or theme a retail store, restaurant, museum or entertainment facility.

Mr. Henningsen pointed out: ""Chemthane 7070 offers numerous advantages over conventional tree fabrications methods - sculpted or moulded fibreglass or Shotcrete. Most notably, the artificial tree bark produced from this process is quicker and easier to install, as well as being adaptable to all sizes/shapes and diameters of tree structures, such as poles and beams.""

""Even on close inspection, the colouring and surface texture is so precise that even an expert might find it difficult to tell if it's real or fake,"" comments a United States National Park Ranger upon seeing a tree made with Chemthane 7070.
