Side springs – made of highly springy steel with resistance above 2000 N/mm2, coated with plastic layer (bezalplast) resistant to UV radiation and environmental conditions (salts, acids, air pollution).
Metal wiper blade parts are made from aluminium and zinc alloys.
Rubber blade – made of compound based only on natural rubber (without synthetic elastomer)
and 12 other chemical components with graphite supplement, improving coefficient of friction and eliminating operational noise. Use of graphite at the stage of blending the compound eliminates graphite residues on the windshield, which often takes place with competitive products that are only surface-coated. MOTGUM wiper blades and rubbers fully comply to FIAT and GM industry standards regarding mechanical properties, wiping effectiveness and ozone resistance.
Plastics – made of PBT (Polybuthylene Terephthalate) – technical material with perfect mechanical properties and high resistance to environmental conditions.
Actually, vast majority of new cars are equipped in flat wiper blades. However, they have different kinds of joints with arms. In the offer of MOTGUM these are marked as wiper blades type B, C, D and E (c.f. catalogue – adaptors for flat wiper blades).
