PVC Membrane – Waterproofing, Roofing & Industrial Protection Solutions
DERFLEX is a leading manufacturer of PVC membrane engineered for long-term durability, UV stability, chemical resistance, and waterproof performance. Our membranes are widely used in construction, roofing, agriculture, environmental engineering, industrial equipment protection, pond lining, and numerous custom applications requiring high-strength flexible materials.
PVC Membrane Product Overview
The DERFLEX PVC membrane is manufactured using premium-grade polyvinyl chloride combined with plasticizers, stabilizers, reinforcement layers (optional), and specialized additives that enhance mechanical strength, UV resistance, anti-aging performance, and overall service life.
Our production facility uses advanced calendering, coating, knife-coating, and lamination technology, ensuring stable quality, uniform thickness, high tensile strength, and excellent dimensional stability. DERFLEX membranes are engineered for outdoor and indoor use under extreme environments including high UV exposure, chemical contact, moisture, saline water, temperature fluctuations, and high mechanical stress.
Whether for waterproofing, structural roofing, pond construction, environmental engineering, agriculture, or industrial applications, DERFLEX provides tailored solutions with optional reinforcement, flame-retardant grades, anti-fungal treatments, geomembrane structures, and custom colors.
Main Features of DERFLEX PVC Membrane
1. Superior Waterproofing Performance
PVC membrane is inherently waterproof due to its dense molecular structure. DERFLEX enhances this by applying thick coatings and tight polymer bonding technology. The membrane maintains 100% waterproof integrity even under long-term immersion, hydrostatic pressure, or continuous rain exposure.
2. UV and Weather Resistance
UV radiation and long-term outdoor exposure are the primary causes of material degradation. DERFLEX PVC membranes are treated with UV stabilizers, ensuring:
- 15+ years outdoor service life
- Resistance to cracking, brittleness, and surface chalking
- Color retention even under direct sunlight
3. High Tensile Strength & Dimensional Stability
Reinforced PVC membranes come with high-tenacity polyester mesh, ensuring exceptional tear strength, puncture resistance, and long-term load-bearing performance. The membrane remains dimensionally stable even under temperature fluctuations.
4. Chemical, Acid & Alkali Resistance
Suitable for industrial, agricultural, and wastewater engineering environments. The membrane resists:
- Acidic solutions
- Alkaline environments
- Saline water
- Organic chemicals (depending on grade)
5. Anti-Microbial & Anti-Fungal Properties
Special additives prevent microbial growth, mold formation, and material degradation in humid or pond-related applications.
6. Flexible and Easy to Weld
DERFLEX PVC membranes can be welded using high-frequency welding, hot air welding, or chemical bonding, ensuring smooth installation and seamless results.
7. Custom Colors, Thickness & Surface Finish
Available options:
- Thickness: 0.3mm – 2.0mm
- Colors: white, grey, blue, black, transparent, and custom colors
- Surface: smooth, matte, glossy, embossed, or textured
