Surface
Finish: Textured
(typically “orange peel" or “desert sand” finish with round or square
slip-resistant pattern on TredSafe top surfaces only)
|
|
UV Stability:
Where applicable Densetec HDPE sheets are manufactured with a standard 5 year
UV protection package. The materials contain 0.1% antioxidant and 0.4% UV
stabiliser in the final product. We would expect this to give a 5 year
protection level dependant upon the conditions where the product is used. Please
note the following sheets do not have a UV protection package as standard:
Utility Board, Partition Board and Cutting Board.

|
Expansion:
The coefficient of thermal expansion for Densetec Design Panel is approximately
1.5mm per metre per 10o C.
|
|
Pigments:
None of our pigments have heavy metal contents in their pigment packages. We do
not manufacture any sheets in colours that contain heavy metals (including
cadmium or chromium). Most of the colours that we supply for playground
equipment, for example, are even FDA approved, meaning that they are safe for
food applications (FDA – US Food and Drug Administration).

suffer from surface flash in any way.
