Model | Thickness(mm) | Wide(m) | Length(m) | Lap edges |
Class P (Plastic) | 1.2、1.5、1.7 | 1、2 | 20 | Unilateral self-adhesive Bilateral self-glue |
Product features
1. Mechanical properties: high material strength, high elongation, impact resistance, puncture resistance, scratch resistance;
2. Bonding performance: the polymer self-adhesive film layer has excellent bonding performance, and the pre-laying anti-adhesive method is used to form a full-adhesive waterproof structure with the main body of the post-casting structure, leaving no hidden danger of channeling water;
3. Aging resistance: excellent UV aging resistance, heat aging performance;
4. Marine environment erosion resistance: salinity resistance, chloride ion erosion resistance;
5. Durability: HDPE can maintain good chemical stability and service life in ordinary inorganic, organic acid, alkali, salt, organic solvent and microbial environment;
6. Environmental performance: green building materials, no pollution to the groundwater environment.
