Most commonly offered Car Wiper Blades are manufactured using natural rubber, and in order to reduce manufacturing costs, the actual rubber blades have various combinations of carbon black and other fillers. Each and every day our Car Wiper Blades are exposed to elements and conditions which contribute to the break up of these fillers and the rubber encasing them. This accelerates the blade becoming stiff and cracking & tearing. Along with actual usage, sunlight, pollution, ozone, and extreme temperatures are the most common causes of windscreen wiper blade break up.
The best Silicone Windscreen Wipers are manufactured of very pure silicone resin. This material is much sought after for its temperature stability, resistance to chemical, pollution, ozone and Ultra Violet degradation, water repellence, and long service life. Silicone resin is used in countless aerospace, pharmaceutical, medical,and automotive applications due to its hugely superior characteristics when compared to natural rubber. The key base raw material in Silicone Wiper Blades - silicone - is also the key base raw material of windscreen glass. This ensures maximum compatibility and conformity between windscreen wiper blade and windscreen.
Therefore, commencing with a better base theoretically produces a better windscreen wiper blade, However that can only be true if everything else measures up to the quality of the best silicone elastomers, from conception, through design, other material choices, manufacturing quality & tolerances to packaging and distribution.
It is really imperative to bear in mind that the actual wiping is done with just a microscopic edge that runs along either side of the tip of the windscreen wiper blade. For maximum performance, this edge must completely follow the curve of the windscreen. Only an extremely Pure Silicone Resin windscreen wiper blade in a high quality frame can ensure this conformity. In addition, because these Car Wiper Blades are made from nearly pure silicone, they leave behind a microscopic coating of silicone oils on the windscreen.
This ensures that after an hour or so’s use, the car owner will observe the build up of a Rain Repellent effect, just like that obtained from those rather costly proprietary windscreen treatments which promote rain repellence & beading. When a high quality silicone windscreen wiper blade is combined with a high quality frame which permits longitudinal flexibility whilst maintaining excellent lateral rigidity & accurate positioning, the whole system reduces the risk of windscreen wiper blade chattering and cuts down the friction which can lead to a worn out wiper motor, blown fuses or thermal cut outs, or mechanical breakdown in the wiper transmission system.
Therefore, if you want to have the last word in safety and performance especially in extreme weather look for Silicone Windscreen Wipers. If you want the ultimate in looks, performance, safety and life look for Silicone Flat Wiper Blades. To make sure that you’re buying high quality Silicone Windscreen Wipers, look for those with a guarantee, and beware of those makers who don’t offer one.
