Non-Metallic Materials
Non-metals are organic substances that do not conduct heat or electricity, and are structurally brittle (cannot be easily rolled, molded, extruded or pressed).
Chemically, the non-metallic elements in the periodic table are hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and selenium. The world of industrial non-metals incorporates substances made from combinations of these elements.
RK Rubber works with non-metallic substances that include:
Cork and Rubber
Plant-derived substance based on an arrangement of cellulose, combined with a polymer and/or vegetable fibers.Properties of Cork and Rubber:
- Easy to Cut
- Light Weight
Typical Application for Cork & Rubber:
- Flanges
Felt Products
Organic wool fibers, can be combined with polymers.Properties of Felt Products:
- Absorbs Oil; Performance is not compromised by Oil Saturation
- Durometer – Hard or Soft
- Insulating
- Resilient, Cushioning
- Resistant to Compression, Fraying, Wear
Typical Applications for Felt:
- Bearings & Spacers
- Gaskets, Rings, Seals, Washers
Non-Asbestos
A composite material of compressed ceramic and/or organic fibers, developed as a safer alternative to asbestos.
Properties of Non-Asbestos Rubber Products:
- Easy to Cut
- Flexible
- Insulating
- Fire Safe
- Thermally Stable
- Resistant to Mild Acids & Bases, High Heat, Inert Gases, Oils, Pressure, Steam, Water
Typical Applications for Non-Asbestos Material:
- Brake Pads
- Clutch Facings
- Gaskets
Vegetable Fibers
Plant-derived substance based on an arrangement of cellulose; can be spun into filaments or matted into sheets. Can be combined with cork and/or a polymer.
Properties of Vegetable Fiber Rubber Products:
- Easy to Cut
- Low Cost
- Insulating
- Low Temperature Performance
Typical Application for Vegetable Fiber Materials
- Gaskets for Low-Pressure Usage
- Insulating gaskets
- Refrigeration gaskets
