Weather resistance and service life: Who is more "durable"?
The weather resistance of PC material is generally poor. Long-term exposure to sunlight can easily cause aging and embrittlement. In high-temperature environments, PC containers may deform and crack, shortening their service life. For example, PC water buckets left outdoors for a long time may show decreased transparency and rough surface after 1-2 years due to ultraviolet irradiation.
Bucket Material Safety Comparison: Health Risks Cannot Be Ignored
The biggest controversy surrounding PC materials is the release of bisphenol A (BPA). Studies have shown that BPA may leach from PC containers when exposed to high temperatures (above 70℃) or after prolonged use. After entering the human body, BPA may interfere with the endocrine system and affect reproductive development, posing a greater risk to infants and young children. Although some PC products currently claim to be "BPA-free", there are still potential risks associated with long-term water storage, especially in hot water or direct sunlight.
