Mineral and natural fiber gasket materials and other sealing products are commonly found in high-temperature insulation, fireproofing, and more. Many industries consider elastomeric minerals and natural fibers for their products, as they can derive maximum benefit from an assortment of high-performance materials. Master Packing and Rubber Company (MPRC) specializes in industrial-strength sealing materials, including mineral and natural fiber gaskets, seals, and compression packing materials. Our durable and reliable custom seals protect the integrity of sealed systems in some of the most demanding industries.

About Mineral and Natural Fibers

Mineral and natural fibers are raw materials that come from plants, animals, or mineral sources. These give our sealing materials the elasticity and resilience they require to hold up in rugged operating conditions, along with the following benefits:

  • High heat tolerance
  • Ability to withstand very high pressures
  • Resistance to a wide range of chemicals
  • Versatility for a wide variety of operating conditions

Depending on the application, we can incorporate specially formulated elastomers to meet customers’ precise sealing requirements.

Key Advantages of MPRC’s Mineral/Natural Fiber Gasket Materials

Our natural and mineral-based fiber gasket materials stand out for a number of reasons, including:

  • Superior thermal resistance. Our mineral and carbon/glass fiber materials exhibit high thermal stability, maintaining a robust seal under extreme heat and temperature fluctuations.
  • Lasting performance. The strength and longevity of our mineral/natural fiber gasket materials allow them to withstand prolonged exposure to high pressures and harsh operating conditions. In doing so, MPRC’s fiber gaskets can also help extend equipment lifespan while reducing maintenance requirements.
  • Cost-effectiveness. By improving durability and wear/corrosion resistance, our fiber gaskets reduce downtime and product replacement costs, making them a cost-efficient sealing option in long-term applications.
  • Environmental resilience. Our gasket sealing materials also maintain impressive resistance to chemical degradation, including oxidation and corrosion. This makes MPRC’s fiber gaskets suitable for varying environments and ambient conditions.

MPRC’s Mineral/Natural Fiber Product Offerings

With an extensive range of specially engineered mineral/natural fiber gasket materials, MPRC’s stock and custom gaskets are an effective solution for a range of industrial sealing requirements. Working closely with our experienced design engineers, we can help customers quickly and easily find the right gasket material for their specific needs.

Compressed Fiber Gasket Sheeting

Compressed fiber sheet products from MPRC meet the rigorous requirements of industrial sealing projects. The fiber material undergoes a carefully controlled hot calendaring process during manufacturing. This allows us to control the thickness of the material and maintain extremely narrow tolerance windows.

Compressed fiber gasket sheets can be used for sealing in chemical processing, power generation, and food and beverage industries.

Aramid Fiber Gaskets

Our aramid fiber gaskets feature high strength and abrasion resistance. They’re also highly versatile and make an ideal choice in medium-temperature settings. Engines, pump systems, and other components used in aerospace and automotive applications can benefit from their durability and reliability.

Glass Fiber Seals

Glass fiber seals from MPRC hold up in extreme settings where other materials might degrade or melt. They are suitable for applications that require both structural integrity and insulating capabilities, such as furnaces and boilers. They can also be used to seal doors and access points in high-pressure and high-heat environments.

Carbon Fiber Components

Carbon fiber is a particularly lightweight yet robust material. MPRC’s carbon fiber components maintain impressive thermal resistance and endurance. They also perform well under high pressures, making them suitable for heavy-duty applications like steam cycling and exhaust systems.
