User manual 3M SUSPENSION DAMPING

[. . . ] Application Profile Market: Hard Disk Drive Assembly Application Description: Suspension Damping 3MTM Ultra-pure Viscoelastic Damping Polymer Constraining Layer Suspension Application Method Applied as die cut parts. PRODUCT 3MTM Ultra-pure Viscoelastic Damping Polymer 242R, 140FO2, JPV-116SF Key Application Requirements Reduce vibration during operation of the Hard Disk Drive (HDD). Benefits/Advantages To Customer Reduces vibration: 3MTM Ultra-pure Viscoelastic Damping Polymer absorbs vibrations of the suspension arm. [. . . ] Surface Type - The 3M ultra-pure viscoelastic damping polymer will form good bonds when properly applied to many high surface energy materials. Materials with a surface energy below 100 dynes/cm2 should be tested to determine if a suitable development of an adequate bond for a given end use application will occur. Application - The 3M ultra-pure viscoelastic damping polymer pplication depends on the polymer selected. Typically, the 242 or JPV polymers can be applied with pressure only. The 140 polymer will require heat and pressure to achieve a good bond. All products should be applied in a manner where air entrapment is avoided. .
