What is PU Film?
Polyurethane film tapes, also known as PU films are versatile adhesive material used in medical, industrial, automotive, and food industry applications. The polyurethane material provides a level of resistance to moisture, chemicals, and abrasions.
Advantages Of Pu Film
Durometer
Polyurethane material comes in a variety of hardnesses. Durometer is the measure of the hardness of a particular material. Most elastomers are measured on the Shore A Hardness Scale for durometer.
Elongation
One of Polyurethane Film's most desirable qualities is its elongation capabilities. Some of our films are able to withstand over 600% elongation before breaking. Polyurethane films also have excellent memory, meaning it will return to its original dimensions after being stretched.
Long-Term Durability
Polyurethane products are manufactured without the use of plasticizers, so it will retain most of its performance characteristics in long-term applications. Not having plasticizers also means it will not leach hazardous compounds in the field. This is of particular importance in the medical industry and in any products intended for use by children.
Low Temperature Flexibility
Polyurethane Film has excellent low temperature flexibility. Most Polyether TPU products retain their flexibility even when exposed to temperatures as low as -60ºF, easily outperforming PVC and making it a perfect material for demanding environments.
Tensile Strength
Our PU films have tensile strength ratings ranging from 4000-9500 psi. This strength enables Polyurethane Film to outperform a multitude of other materials. Because the material is so much stronger than other polymers, our Customers are able to use less material while maintaining, or even improving, the strength of the product.
Antimicrobial / Biocompatibility
Polyurethane film, in most applications, will not support anti-microbial growth while others can have antimicrobial compounds added to them, producing excellent antimicrobial results. Test results can be viewed here. Many of our films have passed stringent biocompatibility testing.
Environmental
Polyurethane is an Earth-friendly material. With the proper equipment, it can be recycled easily and does not release hazardous compounds when being processed or recycled.
Application of PU Film
Automotive
PU Film are used for automotive interior parts, gaskets, seals, and weather-resistant components.
Footwear
PU films are utilized for shoe soles, uppers, and insoles, providing comfort and durability.
Packaging
PU films are used in flexible packaging for food, pharmaceuticals, and consumer goods.
Industrial
PU films find use in industrial applications such as seals, gaskets, and protective covers.
Decorative Laminates
PU films with decorative finishes are used for laminates in furniture and interiors.
Raw Material Preparation
The main raw materials of polyurethane film are polyurethane resin (TPU), plasticizers, stabilizers, catalysts, antioxidants and other additives.
Ingredients and dissolution
The production process of polyurethane films often involves mixing TPU resin with other additives (such as plasticizers, stabilizers, etc.) in a certain proportion. Ingredients are usually achieved through precise weighing and proportioning to ensure consistent performance of each batch of polyurethane film.
Coating or extrusion molding
Coating and extrusion are the two most commonly used processes in polyurethane film production. Which process to choose usually depends on the thickness of the product, application requirements and production efficiency.
extrusion
The extrusion method is a process in which TPU materials are heated to a certain temperature through mechanical pressure and extruded through a mold. Extruded polyurethane films are usually shaped in cooling rollers or cooling water baths.
Cooling, shaping and stretching
Cooling and shaping is a very important step in the production process of polyurethane film. At this stage, the film enters the cooling zone from the hot processing zone and is cooled by natural cooling or cooling rollers to ensure that the film can maintain a stable shape and size during the cooling process.
Post-processing and surface treatment
In order to further improve the performance of polyurethane films, it is often necessary to perform some post-processing and surface treatment on the films.
For some special needs, polyurethane films may need surface functionalization, such as coating with antibacterial layers, breathable layers, barrier layers, etc., to adapt to the needs of different fields.
Cutting and packaging
After the polyurethane film is produced, it is usually rolled or cut into required specifications and sizes by cutting equipment. Special attention needs to be paid to maintaining the integrity of the film surface during the cutting process to avoid scratches or damage.
Quality Control
Quality control is crucial during the production of polyurethane films. Every link in the production process requires strict monitoring and inspection, including the procurement inspection of raw materials, the control of dissolution temperature, coating thickness, stretch ratio, cooling temperature and other parameters.
