What should be paid attention to when storing TPU hot melt adhesive film
What should be paid attention to when storing TPU hot melt adhesive film? Let me give you a brief introduction.
First of all, according to the characteristics of TPU hot melt adhesive film, it is an adhesive product that will melt at a certain temperature, so pay attention not to store it in a place with high temperature. In particular, some TPU hot melt adhesive film products with low melting point need special attention. Once the ambient temperature is too high, the TPU hot melt adhesive film will partially melt, resulting in adhesion between the adhesive layers, leading to use problems.
In addition, TPU hot melt adhesive film should be stored to avoid oil contamination, that is, it should not be stored with oil and other products. Once the surface of TPU hot melt adhesive film is polluted by oil, it will have a great impact on the bonding quality of TPU hot melt adhesive film, and will lead to product bonding problems.
In addition, the TPU hot melt adhesive film needs to avoid being exposed to the hot sun during storage. As a polymer material, TPU hot melt adhesive film is also a plastic product in essence. If over-exposed, the aging process will be accelerated, thus affecting the service life.
In fact, the viscosity and adhesive strength of TPU hot melt adhesive film are two different concepts. Viscosity refers to the viscosity of TPU hot melt adhesive film, which can be understood as the resistance to liquid flow. It can be said that the higher the viscosity, the worse the fluidity. The lower the viscosity, the better the fluidity. The concept of adhesive strength and viscosity is very different. The adhesion strength refers to the adhesion fastness between two adherends after the adhesive is bonded. The small force required to split or break this connection is called binding strength. Therefore, viscosity and adhesive strength cannot be interchanged. Their practical significance is different.
