On cold winter days, PVC hot water bags, with their soft texture and convenient usage, have become a "magic tool" for many people to warm their hands and beds. However, when we fill a hot water bag with water, a question arises: Can a PVC hot water bottle hold water at 100℃? The answer is no. Directly pouring in hot water at 100℃ will not only cause damage to the hot water bag itself, but also may bring a series of safety hazards.
PVC, or polyvinyl chloride, is a common polymer material. It has good flexibility and processing performance, and thus is widely used in the production of hot water bags. However, PVC material has poor stability in high-temperature environments. Hot water at 100℃ far exceeds the tolerance range of PVC hot water bags. When hot water at 100℃ is filled in, the PVC material inside the hot water bag will soften rapidly, making the bag body fragile and extremely prone to swelling and deformation. If there are some minor flaws in the hot water bag itself or defects in the production process, under the effect of high temperature, it is very likely to directly cause the hot water bag to break, and the boiling hot water will gushing out instantly, resulting in a scalding accident. There was once a news report that a citizen suffered from extensive burns on his leg after using a PVC hot water bottle filled with 100℃ hot water. The hot water bag suddenly burst, causing him great pain.
In addition, high temperatures will also accelerate the aging and decomposition of PVC materials. PVC will release toxic and harmful chemicals at high temperatures, such as vinyl chloride monomer. If these substances are inhaled by the human body through skin contact or volatilization into the air, long-term accumulation may pose a potential threat to human health, affecting the immune system and nervous system.
For the safe use of PVC hot water bags, it is recommended to keep the water temperature between 60℃ and 80℃ when filling with water. Before filling water, first check if the hot water bag is damaged or cracked. After filling water, make sure the exhaust port is completely sealed to prevent hot water leakage. During use, do not keep the hot water bag under your body for a long time to avoid it breaking due to excessive pressure. At the same time, do not heat the hot water bag in the microwave oven to avoid explosion.
To sum up, PVC hot water bags cannot be filled with water at 100℃. Safety is no small matter. For the safety and health of yourself and your family, when using PVC hot water bags, you must strictly follow the correct usage methods to avoid accidents caused by improper operation.
