Bitumen Waterproof Membrane Application Cross Laminated Film
What is cross laminated strength film?
It is a high-strength multi-layer composite film,It is made of HDPE as the base material,
adding plasticizer, plasticizer, stabilizer, antioxidant, UV absorber, toughener and other
additives through multi-layer co-extrusion blow molding into embryos, and then by multiple
pull Stretching, then rotary cutting into a film substrate with a horizontal and vertical distribution
of 45 °, and finally through cross-compositing. Due to its cross-stacking structure is different
from ordinary single-layer or multi-layer film, it has the thermal stability, dimensional stability,
two-way tear resistance, two-way uniform tension and high elongation which are not available
in traditional films.
Type of waterproofing membranes:
Advantages:
► Excellent dimensional stability. It can fix its own size without deformation
► Two-way tear resistance. The vertical and horizontal mesh structure effectively solves the phenomenon of easy wrinkling and drumming after construction
► Performance against UV radiation. The use of outdoor high temperature conditions is guaranteed
► High strength and high elongation performance. Excellent resistance to high and low temperature
► Unique puncture resistance, self-healing and continuous tear resistance and excellent nail water tightness. |
