Silica Rope Packing

Silica packings are braided entirely using 6µ continuous filament textured S-TEX silica yarns rated up to 1000°C in optimum conditions.
The base fibres are inorganic, sterile, incombustible and they have low thermal conductivity making them excellent for high heat door sealing applications.
Silica rope packings are available in three different constructions each with their own unique characteristics as explained below.

Constructions Explained

Standard

packings are produced by braiding silica fibre yarn over a compact core of silica fibre yarns. They are compact, firm and flexible with high mechanical resistance and excellent static sealing properties.

Soft Core

packings are produced by braiding silica fibre yarns around a central core of bio soluble fibre insulation. Soft core packings are less dense, lighter in weight but more flexible than standard or brick solid packings. They have high thermal insulation capacity and excellent static sealing properties.

Brick Solid

packings are produced by the “Braid-over-Braid” method where silica fibre yarns are heavy braided over a very compact core of silica fibre yarns. Brick solid packings are a total braided construction and are therefore exceptionally compact, brick solid in density and maintain superior mechanical resistance under pressure, compression and abrasion.

*Standard packings account for 90% of all packings produced, therefore if the construction type is not known, it is standard construction which we will quote for.

Enhancements

Textile Technologies can further enhance the above webbing tapes as follows:

Dry Graphite Dispersion

Apply a dry black graphite dispersion to improve abrasion resistance and aesthetics.

Wet Graphite Dispersion

Apply a wet black graphite dispersion to improve sealing qualities and resistance to hot gases.

Vermiculite Dispersion

Apply a vermiculite dispersion to improve abrasion resistance and increase its temperature resistance up to 1000°C.

Applying a Metal Overbraid

Rope Packings can be covered with a metal outer braid of galvanised steel, stainless steel or Inconel. This creates an extremely robust, abrasion resistant uniform seal.

What is Silica Rope Packing?

Silica rope packing is a high performance sealing material used in demanding industrial environments where conventional insulation or gasket materials may fail. These specialised ropes are manufactured using high purity silica yarns that provide exceptional temperature resistance and durability in high temperature environments.

The base fibres used in silica rope packing are entirely inorganic and sterile, which means they do not burn, degrade easily or support biological growth. This composition also provides low thermal conductivity, with low thermal conductivity making the material ideal for thermal insulation and sealing applications in equipment exposed to extreme temperatures.

Because of these thermal and mechanical properties, silica rope and other technical textiles based on silica fibres are widely used for industrial applications involving industrial furnaces, boilers, and oven equipment where reliable high temperature sealing is required.

How Silica Rope Packing is Manufactured

High quality silica rope packing is produced by braiding high purity silica rope yarns into dense, stable structures designed to maintain performance at elevated service temperatures. During manufacturing, the ropes are braided tightly around a central core to create compact, durable packings capable of withstanding both thermal cycling and mechanical wear.

Different construction methods are used to create packings with specific performance characteristics. These three different constructions include standard, soft core, and brick solid designs, each with their own unique characteristics depending on the required industrial sealing applications.

These braided ropes can be manufactured in a range of round, square, or rectangular profiles with various diameters and thickness options. The choice of construction, profile and diameters allows engineers to select the correct silica rope packing product for specific industrial applications such as furnace door sealing, boiler doors, and oven chamber insulation.

Performance and Temperature Resistance

One of the key advantages of silica rope packing is its outstanding temperature resistance and ability to maintain stability at high service temperatures. Under optimum conditions, silica fibres can withstand service temperatures approaching 1000°C, making these ropes highly suitable for demanding high temperature environments.

The silica rope structure also offers strong mechanical properties, including high strength, excellent flexibility, and good resistance to abrasion. In many industrial systems, these packings must remain stable while exposed to extreme temperatures, vibration and pressure cycles.

When exposed to heat, the silica material retains its structural integrity and thermal stability. This makes silica rope packing a reliable choice for sealing boilers, industrial furnaces, and high heat oven systems where both insulation and mechanical durability are required.

Construction Types and Profiles

There are three different constructions of silica rope packing, each designed to provide specific performance benefits for different sealing applications.

Standard Packing

The standard construction is the most commonly used product, accounting for the majority of packings supplied for industrial applications. These ropes are braided using high purity silica yarns around a dense core, creating a compact, flexible, and durable sealing material.

The standard silica rope packing design provides excellent mechanical stability and reliable sealing performance in furnace, boiler, and oven equipment.

Soft Core Packing

Soft core silica rope packing is produced by braiding silica rope yarns around a central insulation core. This soft core design reduces density while increasing flexibility, making the ropes easier to compress and install in irregular door seals.

The soft core construction offers improved thermal insulation properties and is often used for high temperature sealing around boiler doors, furnace access points, and oven chambers.

Brick Solid Packing

Brick solid packings are manufactured using a heavy braid-over-braid construction that produces extremely dense and durable silica rope packing. These packings are exceptionally compact and offer superior resistance to pressure, compression, and wear.

Because of their high density and mechanical durability, brick solid ropes are often selected for industrial environments where strong sealing performance and abrasion resistance are essential.

Industrial Applications of Silica Rope Packing

Thanks to the exceptional thermal and mechanical properties of silica, silica rope packing is widely used in a broad variety of industrial applications requiring reliable heat resistant sealing.

Typical applications include:

Door seals for industrial furnaces, kilns and oven systems
High temperature sealing applications on boiler doors and heat processing equipment
Thermal insulation around boilers, hot gas ducts and process equipment
Industrial gasket systems using round or square silica rope profiles
Expansion joint and gasket ropes used in high heat industrial systems

In many installations, silica rope packing is installed as round or square ropes depending on the required sealing profile and diameters. These ropes are designed to remain resistant to heat, oxidation and chemical exposure while maintaining their flexible structure.

Because silica rope is both durable and thermally stable, it is primarily used in industrial systems where high temperature sealing performance is essential.

Product Options and Enhancements

Modern silica rope packing products are available in a wide variety of constructions and finishing options designed to enhance performance in demanding industrial environments.

Additional treatments may include graphite or vermiculite coatings which improve abrasion resistance, lubrication and resistance to molten splash. These coatings can also increase the durability of the ropes during repeated thermal cycles.

Different packings can also be supplied in multiple diameters, round or square profiles, and various thickness options depending on the required sealing performance.

These silica based technical textiles are manufactured to deliver excellent durability, strong thermal protection and reliable sealing across a wide range of industrial applications.
