IUGIS Carbon supplies impregnated carbon graphite materials for manufacturers of mechanical seals, carbon bearings, bushings, wear components, pump parts and other industrial carbon-graphite products.
One Product Family, Different Material Solutions
We offer several impregnation systems for different industrial requirements:
Resin Impregnated Carbon Graphite – Focus: Sealing, reduced permeability, chemical compatibility. Suitable for mechanical seal rings, pump components, bearings, bushings, and chemical-process equipment. Best when fluid compatibility and reduced permeability are the main concerns.
Antimony Impregnated Carbon Graphite – Focus: Mechanical strength, hardness, wear resistance. Used for seal rings, bearings, bushings, wear rings, and rotating equipment components. Best when mechanical load, hardness, and wear are major selection factors.
Copper Impregnated Carbon Graphite – Focus: Strength and thermal/electrical conductivity. Suitable for electrical components, thermal-management parts, sliding contacts, and specialized industrial carbon parts.
Silver Impregnated Carbon Graphite – Focus: Specialized electrical, thermal, and sliding applications. Used where high conductivity justifies the higher material cost.
Standard Carbon vs. Impregnated Carbon Graphite
Not every carbon application requires impregnation.The decision should be based on the required performance.

Impregnation is only one part of the material—Final performance also depends on the underlying graphite structure.
Graphite Particle Structure:Affects grain size, density, porosity, and overall material uniformity.
Mechanical Strength:Varies with graphite grade and influences load-bearing capability.
Two impregnated materials using the same impregnant can behave differently if their graphite substrates differ. For OEM applications, we evaluate base graphite + impregnation system together—not the impregnant as an isolated specification.
Thermal Expansion
Different substrates expand differently under temperature, affecting dimensional stability.
Electrical Resistivity
Base graphite determines the starting resistivity before impregnation.
Machinability
Some grades machine more readily than others, affecting component cost and quality.

Impregnated carbon graphite can be supplied in different forms according to your manufacturing process:
Carbon / Graphite Rods:Suitable for machining into seal rings, bearings, bushings, sleeves, and wear components. Available in different impregnation grades.
Graphite Blanks:Supplied per required dimensions and machining allowance for customers who prefer in-house machining.
Semi-Finished Components:Can be evaluated based on drawings for customers who want to reduce machining workload.
Finished Carbon Components:Drawing-based production of finished carbon-graphite components for OEM applications.
Send your 2D drawing, 3D model, or existing sample for technical review.
We recommend a different purchasing process for new impregnated carbon applications.
Step 1 — Define the Application
Tell us what component you are manufacturing and where it will be used.
Step 2 — Review Operating Conditions
We evaluate:
Medium + Temperature + Pressure + Speed + Load
Step 3 — Compare Material Families
Where appropriate, we compare resin, antimony, copper or other impregnated options.
Step 4 — Confirm Material & Dimensions
The selected grade and blank dimensions are confirmed before production.
Step 5 — Sample / Trial
A small quantity can be evaluated before mass production for new applications.
Step 6 — Production
The agreed material and dimensions are manufactured according to the purchase specification.
Step 7 — Inspection & Export
Products are inspected, packed and prepared for international shipment.
