company news about UPASS UV Curing Type PP PA composite film（HBF Model）: Engineered for Extreme Waterproofing Challenges

As an innovator in advanced polymer solutions, UPASS redefines industrial waterproofing standards with our advanced PP PA composite film technology, delivering unmatched durability and chemical resistance for demanding applications. Through state-of-the-art co-extrusion technology that molecularly bonds polypropylene (PP) and polyamide (PA), we've created a material that delivers unprecedented protection and durability.

Why UPASS PP PA Composite Film Outperforms Conventional Materials?

1. Superior Chemical Resistance

• Withstands extreme pH environments  including:

  • Concentrated acids (sulfuric, hydrochloric)

  • Strong alkalis (sodium hydroxide solutions)

  • Saltwater immersion 

• Resistant to:

  • Oil/gasoline exposure

  • Industrial solvents

  • Wastewater contaminants

2. Uncompromising Waterproofing Performance

Engineered for harsh conditions, UPASS's polypropylene-polyamide composite film ensures absolute waterproofing performance.Unlike traditional membranes that degrade over time, our advanced polymer formulation ensures:

• Zero water absorption – No moisture penetration, even under continuous submersion

• Long-term integrity – Resists cracking, blistering, and delamination

• Root & chemical resistance – Protects against biological growth and corrosive liquids

• Seam reliability – Maintains watertight seals under stress and movement

3. Outstanding Mechanical Properties

• Tensile strength: ≥20MPa (MD), ≥15MPa (TD)

• Elongation at break: ≥200%

4. Installation-Optimized Design
