PVC waterproof membrane

< >

Polyvinyl chloride (PVC) waterproof membrane is a polymer waterproof membrane with superior performance, using polyvinyl chloride resin as the main raw material. Adding various special additives and anti-aging components, it is produced with advanced equipment and advanced technology. The overlapping seams adopt hot melt welding process to make the overlapping joints integrated with each other and more reliable.

Product Details

Usage

Roof waterproofing projects
Underground engineering roof waterproofing

Advantages

High tensile strength, high elongation, and small dimensional changes during heat treatment.
Good low temperature flexibility and good adaptability to changes in environmental temperature differences.
Long service life and aging resistance.
Good resistance to root penetration and perforation resistance.
Strong chemical corrosion resistance, suitable for waterproofing in various special occasions.
Convenient construction, welding, solid and reliable, environmentally friendly and no pollution.

Application

1. Surface construction overlap (Using large hot air welding machine)

2. Overlapping of other parts (small hot air welding machine)

3. Processing of pipe nodes out of roof

Storage and transportation

During transportation and storage, different types of products should be stacked separately and should not be mixed. Do not approach fire sources, avoid sun and rain, prevent collision, and pay attention to ventilation. Storage temperature 5℃~40℃. Stack up to two layers. Under normal storage and transportation conditions, the shelf life of sealed packaging is 6 months.

Note:

1. Resistance to static loads is only required for roll materials used for roof covering.

2. The artificial climate accelerated aging time for single-layer rolled roofing products is 2500 hours.

3. Membrane not exposed are not required to undergo accelerated aging testing under artificial climatic conditions.
