As one of the main factors, the Shore A hardness index is used to measure the hardness of flexible materials

such as TPU (Thermoplastic Polyurethane) films. Shore A hardness is expressed on a scale of 0 to 100,

with 0 being the softest and 100 being the hardest. The Shore A hardness index plays an important role in

determining the properties and characteristics of TPU films, including:

1. Flexibility:

Lower Shore A hardness values indicate softer TPU films, which are more flexible and thus suitable for

applications requiring high elongation and deformation without breaking.

2. Tear and puncture resistance:

Higher Shore A hardness values indicate stiffer TPU films, which have improved tear and puncture resistance,

making them more suitable for applications that require greater strength and durability.

3. Clarity:

TPU films with a lower Shore A hardness value tend to be more transparent and clearer due to their higher flexibility

and lower crystallinity, whereas TPU films with higher Shore A hardness tend to be more opaque and less transparent.

4. Adhesion:

The Shore A hardness index of TPU films also plays a role in determining the adhesive properties of the film,

which are influenced by the surface energy and modulus of the material.

5. Processing:

The Shore A hardness of TPU films influences the processing conditions and methods, with harder films requiring

higher processing temperatures and longer processing times to achieve optimal properties.

The Shore A hardness index is an important factor in determining the properties and character of TPU films,

and it must be taken into consideration when selecting the appropriate TPU film for a specific application.

Besides, when TPU (Thermoplastic Polyurethane) films are applied in the medical industry for use as medical devices or materials,

it is essential to take into consideration their biocompatibility and mechanical properties.

The following are the important factors that influence these properties:

1. Biocompatibility:

Biocompatibility is defined as the ability of a material to interact positively with living tissues or organisms without causing

an adverse reaction. Important factors that determine the biocompatibility of TPU films include their chemical composition,

level of leachables and extractables, and the potential for microbial colonization.

2. Cytotoxicity:

TPU films must meet certain cytotoxicity standards to ensure that they do not have a harmful impact on living cells or tissues.

Cytotoxicity testing is carried out to determine if the TPU films release toxic substances.

3. Mechanical properties:

The mechanical properties of TPU films are essential to ensure that the device or material can function adequately in vivo.

These properties include tensile strength, elongation at break, tear strength, and puncture resistance.

4. Flexibility:

TPU films are chosen for their high flexibility, which enables them to conform to the shape of the

body part or organ they are designed to treat.

5. Sterilization resistance:

TPU films must be resistant to sterilization processes such as autoclaving, gamma irradiation,

and ethylene oxide gas sterilization, which are typically used to disinfect medical devices.

6. Durability: TPU films must be durable enough to withstand the stresses of handling, insertion, and measuring.

The production process of thermoplastic urethane (TPU) film typically involves the following steps:

1. Raw material preparation:

The manufacturing process starts with the preparation of raw materials.

TPU film is made from a mixture of aliphatic or aromatic polyester or polyether diols, polyols, and diisocyanates.

2. Polymerization:

The raw materials are mixed together to form a polymer solution. TPU is created by reacting the diisocyanate with the diol,

producing a prepolymer. This prepolymer is then reacted with the polyol to create TPU.

3. Film extrusion:

The TPU polymer solution is fed into an extrusion machine, where it is heated under high pressure to create a molten mass.

The molten mass is then extruded through a die to create a continuous film of uniform thickness.

4. Film cooling and solidification:

The TPU film is then cooled, typically using a water bath, to solidify it and ensure that it maintains its shape.

5. Film treatment and finishing:

After the film has been cooled and solidified, it may be treated with a range of finishes, such as printing, lamination, or embossing.

6. Film inspection and quality control:

The final TPU film product is subjected to stringent quality control measures to ensure that it meets the required specifications.

This includes testing for thickness, tensile strength, elongation, and other physical properties.

7. Film packaging:

Finally, the TPU film is cut to the desired length and wound onto rolls. The rolls are then packaged and shipped to customers.

The production of TPU films involves a multi-stage process that requires careful control of temperature, pressure, and other variables to achieve high-quality films with consistent physical properties.
