Technical Specifications for Polyurethane Replica Wood
The diverse properties of castable polyurethane make it the leading choice of engineers looking for long lasting materials for their high load, high stress environments. Polyurethane routinely outperforms plastic, rubber and steel in its overall ability to resist harsh environmental factors such as abrasion, heat, solvents, oil and acid.
Polyurethane is a resilient, flexible and durable manufactured material that can take the place of paint, cotton, rubber, metal or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber or sticky like glue. Since its invention during the 1940s, polyurethane has been used in a wide range of items, from baby toys to airplane wings, and it continues to be adapted for contemporary technology.
This substance is categorized as a polymer — a molecule that consists of a series of repeating smaller units called monomers — based on its chemical structure. It is manufactured by combining two types of compounds, a diisocyanate and a diol, which are monomers, through a chemical reaction. This makes a basic material whose variations can be stretched, smashed or scratched and will remain fairly indestructible. Depending on the different diisocyanates and diol or polyol constituents, the resulting polyurethane might be in the form of a liquid, foam or solid. Each form has its own advantages and limitations.
Technical Specifications for Composite Render Panels
Maintenance free Composite Render Board is made up of a Polyethylene core sandwiched between two 0.3 mm sheets of aluminium which is coloured Matt White or Ivory on one side and Gloss the other.
This 3mm thick rigid aluminium lined sheet is designed for external use in the construction and industrial sector.
2440mm x 1220mm
