Pu Film

PU film (polyurethane film) is a functional polymer film made with polyurethane as the substrate.

Our Story

Polyurethane Film

Polyurethane (PU) film is a high-performance polymer material renowned for its exceptional flexibility, waterproofing, moisture permeability, and eco-friendly properties. It has emerged as a critical functional material in medical, industrial, and consumer goods sectors.Depending on the type of polyurethane, it can be divided into polyester type (with outstanding abrasion resistance) and polyether type (with better hydrolysis resistance), and is formed by processes such as solution casting, extrusion casting or blow molding.At the application level, PU film can be further divided into non-porous and breathable type (used for outdoor clothing, medical dressings), thermoplastic TPU type (industrial protection) and composite protective film (electronic screens, automotive paint). Its environmentally friendly and non-toxic properties also make it a preferred material in the medical and consumer products fields.

Waterproof PU Film

Waterproof PU (polyurethane) film is a versatile material known for its dual ability to repel liquid water while allowing moisture vapor to escape, making it ideal for a wide range of applications from medical dressings to outdoor gear.

Medical Pu Film

Medical PU Film is a high-performance, medical-grade polyurethane film crafted from biocompatible materials. It excels in breathability, elasticity, and waterproof properties, making it ideal for medical protection, wound care, and medical device applications. Certified under the ISO 13485 Medical Device Quality Management System, it complies with international standards such as YY/T 0471.

Pu Films

Core Characteristics

‌Physical Properties‌:

Thickness typically ranges from ‌0.012–0.035 mm‌, combining lightweight design with high strength and remarkable tear resistance.
Moisture vapor transmission rate (MVTR) reaches ‌3,000–5,000 g/m²/24h‌, with waterproof pressure exceeding ‌10,000 mm H₂O‌ (e.g., medical-grade products).
Broad temperature tolerance (‌-30°C to 120°C‌); some variants support repeated sterilization (e.g., ETO or gamma irradiation).

‌Chemical Stability‌:

Free of plasticizers and solvent residues, compliant with ‌ISO 10993 biocompatibility standards‌, ensuring safety for direct skin or wound contact.

Applications

‌Wound Care

Used as a transparent dressing substrate for burns, post-surgical wounds, etc.

‌Medical Devices

Manufacture of catheter balloons, artificial blood vessels, and interventional tools.

‌Protective Gear

Waterproof isolation layers for medical gowns and surgical drapes.

Parameter	Specification
Thickness	0.01-0.2mm (customizable)
Oxygen Transmission Rate (OTR)	≥2000cc/m²/24hr
Microbial Barrier	Passes ASTM F1671 blood penetration resistance test

Market and Supply Chain

‌Global Production‌: China accounts for ‌over 65%‌ of global PU film output (key manufacturers include Zhejiang Kebang, Jiangsu Shuangxiang).
‌Pricing‌: Industrial-grade products cost ‌$1.5–3/m²‌; medical-grade prices double (requires sterile certification).
‌Trends‌: The global market is projected to reach ‌$1.2 billion by 2025‌, growing at an ‌8.2% CAGR‌ (Source: Grand View Research).

Selection Guidelines

‌Medical Use‌: Prioritize ‌low-allergenic adhesive types‌ with ‌ISO 13485 certification‌.
‌Industrial Use‌: Choose ‌aromatic PU‌ (high-temperature resistance) or ‌aliphatic PU‌ (UV resistance) based on thermal requirements.

Through continuous innovation (e.g., nano-coatings, renewable raw materials), polyurethane film rolls are expanding into cutting-edge fields such as ‌new energy battery separators‌ and ‌flexible electronics‌, demonstrating vast application potential.
This article systematically outlines the core advantages and market dynamics of PU film rolls. For detailed insights into specific products (e.g., medical pressure-sensitive adhesive films), feel free to provide further requirements for in-depth analysis.
