Langwei PVC waterproofing membrane in PVC resin as the main material, based on scientific formula, adding plasticizers,stabilizers, anti-UV agents, pigments and other additives, after kneaded material, extrusion process and composite nonwoven fabric
made of polyester with good waterproof performance elastomeric waterproofing membrane. membrane width of 2.10 meters,specifications, thickness, width can be reasonably adjusted according to user needs. Widely used in underground seepage, light
steel roof waterproof insulation, sewage treatment plants, landfills, chemical acid treatment pond building roof, waterproofing underground works, underground tunnels, road tunnels, reservoirs, dams and other projects, etc. seepage and corrosion-resistant liner environmental engineering use.
Langwei PVC membrane is high-grade polymer waterproofing membrane produced with more than ten years experience, absorbing
advanced foreign technology, using imported equipment and process. The waterproofing membrane in PVC resin as the main raw
material, adding a variety of special additives and anti-aging components, sandwiching a polyester fiber fabric or glass fiber
fabric reinforcement material base for the child, the use of imported equipment and advanced technology production system to make.
This product and homogeneous (excluding internal reinforcing material) compared to PVC waterproofing membrane, the greater tensile
strength, elongation, shrinkage rate is very small, longer life and other notable features. The product is stable performance,
▲ homogeneous membrane (H class) → plasticity for detail processing and complex roofing project.
▲ with fiber sheet (L class) → single composite polyester nonwovens, combined with a more secure and grass-roots; mainly used
exposed roof, Exalted roof, underground engineering.
▲ polyester fabric reinforced sheet (P type) → high tensile strength, superior mechanical properties; mainly used in single-layer
roof exposed to mechanical fixing systems and other projects.
▲ glass fabric reinforced sheet (G category) → dimensional stability, resistance to puncture roots; mainly used exposed fully
adhered roofing system, empty shop protection system, planted roof, garage roof and other projects.
▲ Glass fibers reforced and enhanced with fiber backing sheet (GL Class) → enhanced web integration advantages, combined with the
grass roots firmly safer, better dimensional stability over a backing roll set with fiber and glass fiber inner.
★ surface layer of special treatment, prolong life
★ with identifying colors, easy to repair
★ puncture resistant root system for green roofs
★ fiber reinforced polyester inner membrane, anti-perforation and pressure resistance, superior mechanical properties; suitable
for exposed mechanically fastened roofing system works
★ glass fiber reinforced inner membrane, good dimensional stability, suitable for exposure fully adhered roofing system, empty
shop protection systems, garage roof and other projects
1. Excellent physical properties
Soft PVC waterproofing membrane with high strength, high elongation, low temperature flexibility, good dimensional stability, more
suitable for use underground waterproof projects.
2. Long life, durability
Long Wei company developed the PVC waterproofing membrane, with a unique feature Party system, the first choice of good
compatibility, high plasticizing efficiency, Low volatility, low extraction, low migration of plasticizer system, so products have
excellent durability performance, and environmental protection -35 ℃ test strip under parts, coil does not rattle occur.
3. Good light and heat stability
Selection of long-term nature of light, heat stabilization system, while preventing under high temperature and sunlight coil
thermal aging and light oxygen aging, long-term use will not have a groundwater source environment and build cooperation as
4. Fungal resistance
Waterproofing membrane during use are exposed to all kinds of micro-organisms in nature, it is necessary to maintain long-term
resistance to fungal, PVC material itself undermine the action of microorganisms having a strong resistance, but the choice of
security the plasticizer has a very good anti-fungal;
5. Excellent acid, alkali can
In order to make the products meet groundwater and concrete alkaline water,
Long Wei companies, especially developed underground product formulations, It has excellent resistance to acid, alkali, salt
corrosion resistance, and thus full foot overall water needs of the project.
6. Environmental Adaptability Evaluation
PVC waterproofing membrane occurs under the action of light degradation, but in light PVC HCL off very slow, can not use the
general method to test, PVC waterproofing membrane temperature between -40--90 ℃, temperature adaptation wide range and resistance
to inorganic acids, alkalis,salts, but should avoid sulfide pollution, and away from heat.
