Motor housing in vacuum cleaner

Plate 26 The motor housing In this moulding, the special features required are [Pg.39]

Polycarbonate is the only polymer to offer this combination, and this complex moulding is successfully made in this material. [Pg.40]

Other materials offer other combinations - note the rejection of PC for the mower parts because of its susceptibility to ESC. [Pg.40]

Impact resistance is offered by ABS, acetal copolymer, noryl etc., but these polymers cannot be used for transparent products. [Pg.40]

Transparency is offered by, e.g. acrylic resins, e.g. poly methyl methacrylate, but there the resistance to high temperatures is poor. Polycarbonate can be used satisfactorily at 130-140 C. Polystyrene polymers can be made into transparent products, but again temperature and impact resistance is inadequate. [Pg.40]
