It’s time to hit the great outdoors for some serious summer fun! So let’s make sure you have everything you need:
- Bathing suits
Chemistry? Yes, it’s an essential element in those summer adventures! Let’s explore all the way chemistry makes it’s possible.
As a lotion or spray, sunscreens contains chemical compounds to either absorb or reflect ultraviolet light to protect your skin from damage and lower your risk of skin cancer.
Oxybenzone can absorb UVA and UVB light. Titanium dioxide, zinc oxide, or a combination of the two form an opaque material to reflect the light.
Remember to apply liberally, and often, especially if you’re in the water!
Bathing Suits and Water-Resistant Technology
Many bathing suits are made from strong synthetic fabrics and dyes that are designed to withstand repeated use, washings, sun, salt and other elements. For those that swim for sport, there are swimsuits designed with specific elements (occasionally silver) that help with circulation and reduce drag in the water.
Silicones enable new techniques to design sportswear that is lightweight, durable, water repellent and high performing, while allowing the fabric to maintain “breathability”. They help make leather shoes and raingear waterproof. And they seal out water from goggles and diving masks.
Kayaks and Sports Equipment
Polycarbonate plastic is used in sports safety equipment such as bicycle helmets, shin guards and goggles for its shatter-resistant properties.
There are several different processing methods used to make plastic products. One of them, rotational molding, consists of a closed mold mounted on a machine capable of rotation on two axes simultaneously. Plastic granules are placed in the mold, which is then heated in an oven to melt the plastic.
Rotation around both axes distributes the molten plastic into a uniform coating on the inside of the mold until the part is set by cooling. This process is used to make hollow products, like canoes and kayaks.
