Here are a few key points about sunscreen fabric:

UV Protection: Sunscreen fabrics are designed to block or minimize the penetration of UV radiation through the material. This helps to protect the skin from sunburn, premature aging, and potential long-term damage caused by UV exposure.

UPF Rating: The UPF rating measures the amount of UV radiation that is allowed to pass through the fabric. For example, a fabric with a UPF rating of 50 allows only 1/50th (or 2%) of UV radiation to penetrate, providing high sun protection.

Breathability: While sunscreen fabrics are effective at blocking UV rays, they can vary in terms of breathability. Some fabrics may allow for better air circulation, which can help keep the wearer cool and comfortable in hot weather conditions.

Applications: Sunscreen fabrics are commonly used in the manufacturing of clothing and accessories such as hats, shirts, pants, swimwear, and outdoor gear. They are particularly popular for outdoor activities like hiking, swimming, and sports where sun exposure is a concern.

It's important to note that sunscreen fabrics are not fireproof or flame-resistant. If you require fire-resistant properties, you would need to consider fabrics specifically designed for that purpose, which are different from those designed for sun protection.

Fire-resistant fabrics are treated or manufactured to be resistant to ignition and to slow down the spread of flames. These fabrics are commonly used in protective clothing for firefighters, industrial workers, and other high-risk environments.

Sunscreen, on the other hand, is a product designed to protect the skin from the harmful effects of UV radiation from the sun. It is available in the form of lotions, creams, sprays, or sticks that are applied directly to the skin.
