Dimensional HDPE 0.26mm 260um Cross Laminated Film
Cross Laminated Film For Bitumen Waterproof Membranes
Description:
It is multi-layers laminated film with high strength property, made via three layers co-extrusion
film blown process and special stretching technology. The inner crossed structure differs from
traditional films with one layer or many layers, possesses both thermal stability and dimensional
stability, good bidirectional tear resistance & high tensile strength, as well as high elongation
at bi-direction.
The Production Process:
OUR THREE STEP PROCESS FOR MANUFACTURING HIGH STRENGTH, DURABILITY,
AND QUALITY CROSS LAMINATED FILM.
Step 1: FILM BLOWING
Step 2: Spiral Cutting
Step 3: Cross Lamination
| Why Cross Laminated? |
| 1. Puncture Resistance: less accidental damage |
| 2. Thermal Dimensional Stability: No fish-mouthing or controlled shrinkage |
| 3. Cold temperature resistant down to -30°C/-20°C |
| 4. Cross laminated film allows waterproofing membranes to bridge gaps in sheathing and is resistant to damage from incidental movement and settling of the roof |
| 5. UV Stability for typical job site exposure |
