Improved stiffness and heavy-duty construction of truck wiper blades is achieved by using riveted joints , which is a very important feature considering large lengths of wipers used in transport vehicles. Thanks to a special adaptor system these wiper blades can be mounted on virtually any truck or bus manufactured anywhere in the world.
Anti-corrosion resistance: above 480 hours (salt chamber test, specifications in acc. with ASTM B – 117).
Rubber blade – made of a rubber compound based on 100 per cent natural rubber and 12 other chemical compounds with addition of graphite which improves friction factor and prevents noisy wiper operation. A unique technology of adding graphite on the compound level – rather than spraying it on the surface – eliminates any residue on the windscreen. MOTGUM rubbers blades comply with respective FIAT and GM norms regarding mechanical properties, wiping quality and ozone resistance.
Side stringers – made of acid-resistant steel 1.4301 (1H18N9) of strength exceeding 1500 N/sq. mm.
Metal parts (brackets) – made of strain-hardened steel sheets with anti-corrosion aluzinc coating above 25ľm.
Plastic parts – made of PBT (Polybutylene Terephthalate) – a plastic resin of exceptional mechanical properties and high endurance to atmospheric factors.
Coating – paint: polyester resin of high resistance to UV radiation and atmospheric factors (salts, acids, exhaust pollution).
MOTGUM wiper blades for trucks and buses comply with FIAT 9.93605 and DAEWOO EDS – M – 7501 norms regarding functionality and material properties. Both rubbers and complete wiper blades are certified with „B” safety certificates (compulsory for all automotive parts sold in Poland). The entire process of manufacturing is periodically qualified and evaluated by MOTGUM’s major consignees.
