|Test Result Summary:|
- Variances depending on wood species.
- Water absorption of up to 43%.
- Swelling of up to 5% in thickness and width.
- Variances depending on manufacturer and quality of MDF.
- Huge water absorption (90%).
- Swelling of up to 80% in thickness.
- Delaminating of exterior foil.
- Turn green after products have dried.
|High Definition Polymer System (HDPS)
- No major dimensional variances as shown in the photographic evidence.
- Excellent moister resistance; molding have to be properly installed and ends need to be covered with adhesive.
- Water absorption is less than 1% in weight
