Wiper blades are typically made from rubber or silicone. Rubber is the most common and affordable option, but it tends to wear out faster. Silicone blades last longer and perform better in a wide ...
Most early wipers used a rubber blade attached to a flat metal base. But as aerodynamic and styling concerns introduced curved windshields, these proved insufficient. In 1945, John W. Anderson, founder of Trico rival Anco, filed a patent for a wiper with branched arms to keep the blade pressed uniformly against both curved and flat glass, [16 ...
The primary use of Rain-X is for automotive applications. Commercially sold "Original Glass Treatment" is the original and most well known Rain-X branded product. It is a hydrophobic silicone polymer [3] that forces water to bead and roll off of the car, often without needing wipers. It is sold in bottles of 3.5 or 7 US fluid ounces (100 or 210 ...
1954: Four-Bar Blades. Early heavy duty wiper blades. 1956: Panoramic Rainbow or “P-R” Blades. The first windshield wiper blades to have an arc. A pair of spring-tensioned levers pre-flexed the blades to maintain constant pressure on the windshield. It was TRICO's most popular blade up to and through the late 1960s. 1957: TRICO Australia.
Silicone rubber is a reliable solution (as opposed to rubber and thermoplastic elastomers) for migration or interaction problems between the main active ingredients. Its chemical stability prevents it from affecting any substrate it is in contact with (skin, water, blood, active ingredients, etc.).
EPDM rubber (ethylene propylene diene monomer rubber) [1] [2] [3] is a type of synthetic rubber that is used in many applications. EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers with a saturated polyethylene chain (the M deriving from the more correct term polymethylene).
