11. What are sunscreens? Which component is usually used in the sunscreens
12. Why are silicones used in various industries?
Answers
Answer:
11. Sunscreens, also called sunblock, contain the active ingredients titanium dioxide or zinc oxide and protect the skin by deflecting the sun's rays. Titanium dioxide is often a primary ingredient in sunscreen because it works well as a UV filtering ingredient.
12. Valued for their electrical-insulating properties, chemical stability, and the wide temperature range over which they retain resiliency, silicone rubbers are used mainly in O-rings, heat-resistant seals, caulks, gaskets, electrical insulators, flexible molds, and (owing to their chemical inertness) surgical implants.
