Packing fillers

Glass fiber: These types of fibers are produced for the first time in 1930. Made of natural materials, these products are environmentally friendly and not harmful to human health. Having excellent insulation properties, lightweight, high strength they easy can be bend and wrapped, which makes them very attractive and useful in the sealing materials. 

Aramide fibersThese are artificially build fibers made from molecules linked by Hydrogen bonds, which transfer mechanical stress with high efficiency.  The term “aramid” is an abbreviation of “aromatic polyamide” and was first used in the 1960s. The aramid fibers have a high tensile strength, good resistance to abrasion and solvents, not conductive, have a low flammability and maintain its integrity at high temperatures.

(е)PTFE: This type of materials are among of most used in places with high chemical activity. Developed in the 1930s, he endured the attack of the harshest chemicals – concentrated acids and alkalis. With working temperature up to 250 °С degrees, low friction coefficient and negligible influence of UV rays in the yearly 1970s this material becomes even more attractive with name as expanded PTFE (ePTFE). This gives more strength per weight ratio, low coefficient of absorption of water and steam. It`s best advantage over most technical plastics is it`s stability when deformation forces are applied. The material manages to keep it`s shape under load and it is easy to be machined in ready made parts.

 Inconel wire: This material is referred to as a “super alloy” and it is known as one of the most resistant to corrosion after the gold and platinum. Usually it is used in places with higher temperatures and pressure. Inconel has an ability to create solid oxide layer when pressed under high pressure. This layer protects the sealing material from the aggressive attacks of the working flow. The standard ratios in this alloy is close to: 75% Nickel, 20% Chrome, 2,5% Manganese and small percentage  iron. The ratios are based on the current usage.

 Expanded Graphite: This type of graphite is mainly used when extremely high temperatures, especially when working in the chemical and petrochemical industry. For applications in nuclear power plants expanded graphite with a very high purity of (99.85%) is used. The material has excellent thermal stability, impermeable to liquids and gases.
