EVA material itself has good flexibility and resilience. When the raincoat film is stretched, bent or folded to a certain extent, it can return to its original state by its own characteristics and will not easily crack or break. For example, when a child is playing in an EVA raincoat, he may frequently move his arms, bend over, etc., and the EVA raincoat will undergo various deformations. The EVA raincoat film can adapt well to these movements and remain intact. Its durability is reflected in its resistance to daily friction and minor collisions. During normal use, the raincoat will rub against the child's clothes, surrounding objects, etc., and the EVA material can withstand this friction without being easily worn. For example, when a child is outdoors, the raincoat may have slight contact with objects such as branches. Due to its durability, it is generally not easily scratched.
Under normal weather conditions, such as light to moderate rain, the impact of rain on the raincoat is relatively small. With its flexibility and durability, EVA raincoats can effectively block the penetration of rainwater, and its own structure will not be damaged by the impact of rainwater. Even if children run and jump in the rain, the raincoat can remain intact. When children are doing some regular activities, such as going to and from school, playing in the park, etc., the flexibility and durability of EVA raincoats are enough to cope with the various movements and external factors brought about by these activities. For example, when a child walks with a schoolbag on his back and wearing a raincoat, the friction between the schoolbag and the raincoat and the twisting of the body will not easily cause the raincoat to be damaged.
If the child encounters a large external impact, such as being directly scratched by a sharp object (such as a stone, glass fragments, etc.) when falling, or being pulled strongly, exceeding the limit that the EVA material can withstand, the raincoat may be damaged. Because any material has its upper limit of tolerance, EVA raincoats are no exception. In some special activities, such as when children engage in intense outdoor sports such as rock climbing and wrestling, the raincoat may be overstretched, squeezed or rubbed. In this case, even EVA raincoats with good flexibility and durability may be damaged.
If children use raincoats improperly for a long time, such as repeatedly rubbing against sharp objects, deliberately scratching the raincoat with sharp objects, etc., the surface structure of the raincoat will gradually be damaged, reducing its flexibility and durability, and eventually causing damage. If the raincoat is exposed to harsh environments for a long time, such as high temperature and strong ultraviolet rays, the EVA material may age, and its flexibility and durability will decrease, thereby increasing the risk of damage to the raincoat.
