WebJun 9, 2024 · An SPF 30 allows about 3 percent of UVB rays to hit your skin. An SPF of 50 allows about 2 percent of those rays through. That may seem like a small difference until you realize that the SPF 30 is allowing 50 percent more UV radiation onto your skin. WebJan 1, 2016 · At one end, higher stress (e.g., for those knees with modest contact area) can produce fatigue-type highly accelerated wear that must be avoided in design. At this extreme, when the stress is very high, the wear factor of UHMWPE is bound to rise (which means the wear rate rises faster than just with rising load).
