Notes:
- Re-Plast is dark colour. Special additives as well as its dark
colour render the product very resistant to ultraviolet (UV) penetration.
- Re-Plast also contains additives which moderate the spread of flames.
- The above mentioned results are for indicative purposes, thus allowing
comparision with other materials.
- A slight color fading of the Re-Plast lumber, when exposed to sunlight,
is normal and does not harm the product.
