Below is a detailed comparison between the silicone straps and rubber straps of the swim goggles:
Softness and comfort when wearing
Silicone strap: better softness, comfortable touch, high affinity to the skin, will not cause greater pressure on the head skin and strangulation when wearing, suitable for long time wearing.
Rubber straps: relative to the silicone straps are more rigid, especially the ordinary rubber material, there is a certain sense of roughness, wear may produce strong friction and pressure on the skin, long time wear may lead to head discomfort, or even strangulation marks.
Durability
Silicone straps: have excellent mechanical properties, good tensile strength and elongation, normal service life of up to 3-5 years. It is resistant to ultraviolet rays, ozone and aging, and is not easy to be hardened, brittle and deformed due to prolonged use, and its tear-resistant performance is also excellent, and it is not easy to be torn.
Rubber straps: the durability of ordinary rubber material is not as good as silicone, long-term exposure to the air is easy to aging, hardening, brittleness, discoloration and other phenomena, the general use of 1-2 years after the elasticity will be significantly reduced, prone to breakage, breakage and other situations. However, some rubber straps with special treatment or added specific ingredients will improve in durability, but usually still not as stable as silicone.
Color Fading
Silicone straps: high-quality silicone material is stable, usually does not lose color, and the color can be maintained for a long time.
Rubber straps: lower quality rubber straps may lose color, especially the darker colored ones, which may fade after a period of time, affecting the aesthetics.
Elasticity and retention
Silicone straps: good elasticity, and can quickly return to its original state after stretching, not prone to elastic fatigue, can maintain a good fit and fixation for a long time, not easy to loosen or deformation.
Rubber straps: the elasticity of new rubber straps is still good, but after a period of time, the elasticity will gradually weaken, especially in the case of frequent stretching and relaxation, elastic fatigue is likely to occur, resulting in the straps become loose, unable to provide good fixation, and need to be adjusted frequently to adjust the degree of elasticity.
Easy to break degree
Silicone straps: high tensile strength, normal wear and use, not easy to break, unless subject to excessive pulling or sharp objects such as scratches and other accidents.
Rubber straps: relatively poor strength and toughness, easy to break, especially when the rubber material is aging or impacted by external forces, the risk of breakage is higher.
