PU Film Manufacturers

Our colored waterproof breathable film is mainly made of TPU/PU blank film, which is processed by our company with various patterns. It can be specifically divided into six series: ordinary printing film, photosensitive TPU, luminous TPU, fluorescent TPU, iridescent printing film, polythermal printing film, and graphene printing film, with more than 1500 patterns. Its waterproof and nonfading characteristics make the beautiful appearance last forever, allowing the originally monotonous waterproof breathable film to have infinite color changes and visual sensations. It inherits the excellent physical properties of waterproof breathable film while saving processes and eliminating the need for repeated bonding, reducing costs. Its application range has been widely extended and expanded, and it has been highly praised by customers. The products are exported to the United States, Europe, Japan, South Korea, Australia, Hong Kong, Southeast Asia, and other places.

Can the PU film maintain its waterproof properties while allowing moisture vapor to escape? 

PU film can indeed maintain its waterproof properties while allowing moisture vapor to escape, which is a key feature of breathable fabrics and films. This is commonly referred to as waterproof-breathable technology.

Waterproofing Mechanism:
The PU film is designed to prevent water from passing through, typically using a dense molecular structure that blocks water molecules. This makes it waterproof and ideal for applications where moisture from the outside needs to be kept out (e.g., jackets, rain gear, or outdoor equipment).

Breathability:
Despite being waterproof, PU film can still allow moisture vapor (sweat) to escape. This is typically achieved through the micro-porous structure of the PU film, where the pores are small enough to block liquid water from passing through but large enough to let water vapor molecules escape.

The moisture vapor permeability (MVP) of PU films can vary, but high-quality PU films often have breathability ratings between 1,000 to 10,000 grams of water vapor per square meter per 24 hours (g/m²/24hr). This indicates how much moisture vapor can pass through the film over a day.

Moisture Regulation:
This combination of waterproofing and breathability makes PU film perfect for applications like outerwear, footwear, and medical textiles, where keeping the wearer dry from external water (e.g., rain) is important, while also allowing perspiration to escape, preventing discomfort and overheating.

Performance in Different Environments:
The performance of waterproof-breathable PU films can be influenced by temperature and humidity. In warm or humid conditions, the vapor permeability helps prevent moisture buildup inside the garment or product, making it comfortable to wear. In cold environments, the moisture can still escape, while the waterproof barrier helps retain warmth by keeping external water out.

Applications:
The balance of waterproofing and breathability is especially important in sportswear, outdoor clothing, medical pads, and sleeping bags, where the goal is to keep the body dry without causing excessive sweating or moisture buildup.

High-quality PU films can indeed maintain their waterproof properties while allowing moisture vapor to pass through, making them ideal for applications that require both water protection and breathability.
