What Are the Characteristics and Performance Evaluation Methods of Flame Retardant TPU Materials?

Flame retardant TPU, as the name suggests, has good fire resistance. This substance may sound unfamiliar to many people. In fact, it is ubiquitous in our lives, as it is used in the production of many things. Let's talk about the characteristics of general flame retardant TPU.

Characteristics of flame retardant TPU

Wide hardness range:

Quality-assured flame retardant TPU can obtain products with different hardness by changing the ratio of the reactive components. With increasing hardness, it also affects the continued development and maintenance of the original good wear resistance and elasticity of the company, so flame retardant TPU can be more widely applied to many aspects.

Excellent cold resistance:

Flame retardant TPU has a low possibility of changing temperature in the glass state, and it can maintain good physical properties such as elasticity and flexibility at -35 degrees Celsius.

High mechanical strength:

Quality flame retardant TPU has strong bearing capacity, good impact resistance, and is not easily broken by general impact. Moreover, its shock absorption performance is also very outstanding.

Good processing performance:

Flame retardant TPU is usually processed by thermoplastic materials, such as calendering, injection molding, and extrusion. In addition, by processing flame retardant TPU with some polymer materials, a polymer alloy with complementary properties can be obtained. This material is resistant to molds, grease, and water, and has good recycling performance.

How to judge the advantages and disadvantages of flame retardant TPU mainly?

Mechanical system properties:

Quality-assured flame retardant TPU has a good elastic body, and its tensile strength is closely related to its hardness. With the increase in hardness, its tensile modulus and tear strength will continue to increase, and its rigidity and compression load management ability can be increased, and its elongation rate will decrease. This is primarily due to the significant increase in content due to different hardness. Density and dynamic heat problems will also be increased.

The tear strength of flame retardant TPU is also greatly influenced by hardness. With the enhancement of hardness, the tear strength can also increase rapidly. In addition, the performance of TPU elastic plastic also includes the high-cost shear work strength and impact force.

Physical properties:

The hardness of quality flame retardant TPU has a great relationship with temperature. If the temperature suddenly drops to -4 degrees Celsius to -12 degrees Celsius, the hardness of flame retardant TPU will not change significantly. If the hardness of TPU suddenly becomes very hard and loses elasticity at low temperatures, this is due to crystallization. Flame retardant TPU also has strong corrosion resistance and acid resistance. Although it has certain hardness, it has good flexibility in producing TPU for shoes.

Flame retardant TPU is a very lively material with many excellent properties that can be arranged and combined in industrial production. However, there are many difficulties in actual formula design and industrial production, and there may even be some technical problems that are difficult to achieve with flame retardant TPU. However, from the current situation, flame retardant TPU material still has high use value. Its application in many fields has been well evaluated. If more funds are invested in the development of flame retardant TPU, its application will be more extensive.
