Advantages And Disadvantages Of TPU Composite Fabric

The advantages and disadvantages of TPU composite fabrics, tpu composite fabrics are made of TPU films on various fabrics to form a composite material, and a new type of fabric is obtained by combining the characteristics of the two.
TPU (thermoplastic polyurethanes), thermoplastic polyurethane, is a linear block copolymer composed of oligomer polyol soft segment and diisocyanate-chain extender hard segment. TPU can be made into film by salivation, film blowing, calendering or coating. It has the superior characteristics of good elasticity, toughness, wear resistance, good cold resistance, environmental protection and non-toxicity.
Advantages and disadvantages of TPU composite fabric
The name of tpu composite fabric/cloth is thermoplastic elastomer rubber. This material can become soft under a certain heat, and the composite cloth can remain unchanged at room temperature. It is used for stable support on shoes. Tpu composite fabric/fabric The main features of are these:
Wide range of hardness: By changing the ratio of the reactive components of the tpu composite fabric/cloth, the tent fabric can obtain products with different hardness, and with the increase of hardness, the product still maintains good elasticity and wear resistance.
High mechanical strength: TPU composite fabric/fabric products have outstanding bearing capacity, impact resistance and shock absorption performance.
Outstanding cold resistance: the glass transition temperature of tpu composite fabric/cloth is relatively low, and the canvas factory still maintains good elasticity, softness and other physical properties at minus 35 degrees.
Good processing performance: tpu composite fabric/cloth can be processed by common thermoplastic material processing methods, such as injection molding, extrusion, calendering and so on. At the same time, the co-processing of tpu composite fabrics/cloths and certain polymer materials can obtain polymer alloys with complementary properties.
Resistant to oil, water and mold. Good recycling.
There are two methods for tpu composite fabrics, one is post-lamination: first make a tpu film and then glue it on the fabric, and the other is online lamination: apply glue on the fabric or not glue it, and directly put the tpu on it The fabric is made of tpu composite fabric or sandwich fabric.
Generally, the scale of post-lamination processing factories is small. There are many small factories in China. The process of post-lamination requires high temperature and high pressure on the tpu film again. Improper process control will cause damage to the film and even small holes.
