PURPOSE:The titled composition capable of forming a plastic magnet having excellent magnetic and mechanical characteristics with good moldability, comprising a polyamide resin, a silane coupling agent containing amino groups, a polydimethylsiloxane, and magnetic powders. CONSTITUTION:5-15wt% polyamide (e.g. powdered nylon 6), 0.05-3wt% silane coupling agent containing amino groups (e.g. gamma-aminopropyltriethoxysilane), 0.05-3wt% polydimethylsiloxane (with a molecular weight of about 5,000- 50,000), and 79-94.9wt% magnetic powders (e.g. powders of barium ferrite or samariumcobalt) are compounded. |
