 ADVANCED MATERIALS PREPARATION POLISHING PADS
Many of the emerging technologies use sapphire, silicon carbide and ceramic wafers to have a very flat surface and high degree of surface finish with low defect densities. The polishing of these materials requires use of different pads and slurries and the modification of the basic variable parameters that are applied to the polishing machine. Spartan Felt Company has a developing line of pads that address the critical needs of these hard materials.
POLISHING PAD DETAILED INFORMATION
All pads are available plain and perforated. Embossing is available, but limited. Please inquire about specific applications.
All pads are available with our own specially developed PSA, magnetic or loop backing to be used with various hook attachments. We currently have 2 types of PSA that cover 2 specific markets. Our standard is for the glass industry is one that resists temps up to 120F, peels easily from the plate and can actually be reapplied. Our second type of PSA is a 3M product that is temperature resistant up to 160F, resistant of pH changes from 5 to 10, but may leave some adhesive on the plate (depending on how it is ran and removed).

Poretex Polishing Pad
DESCRIPTION: |
In the surface preparation process, there is a need to produce ultra polished
surfaces with synthetic pads. Spartan Felt Company’s suede polishing material is
designed to generate final polished surfaces using submicron
slurries. It’s
unique, resilient design allows the pore structure to recover from polishing
compression and setsup
a fluid transfer action with the slurry. Poretex Pads are
available in plain, embossed or textured front surfaces. Pressure sensitive
adhesive is standard for use with a wide pH slurry range. |
