High-conductivity compound

Overview
Filled PTFE compounds (polytetrafluoroethylene) formulated with fillers such as glass fiber, carbon, graphite, bronze, MoS2 and PEEK to modify mechanical, thermal, electrical and tribological behavior for industrial parts and components.

Properties and Performance

• Mechanical: increased hardness and compression strength with reduced cold flow (creep) depending on filler type and loading.
• Thermal: lower linear coefficient of thermal expansion and improved dimensional stability at elevated temperatures.
• Electrical: adjustable electrical conductivity when conductive fillers (carbon, graphite) are used.
• Tribological: lower coefficient of friction and reduced wear rate with solid-lubricant or metal fillers.

PTFE Compounds — Typical Materials and Functions

• Glass fiber — Up to 40%: improves wear resistance, compression strength and creep resistance; good chemical stability; typical color white/cream.
• Carbon — Up to 35%: increases electrical and thermal conductivity, load-bearing capacity and wear resistance; low friction in dry, water or steam environments; typical color black.
• Graphite — Up to 25%: enhances sliding against soft metals, reduces friction and improves wear resistance; chemically inert; typical color black.
• Bronze — Up to 60%: increases compression strength, thermal conductivity and abrasion resistance; reduced chemical resistance; typical color dark brown.
• MoS2 (molybdenum disulphide) — Up to 5%: raises hardness and wear resistance, improves sliding properties and lowers friction; typical color blue-azure.
• PEEK — Up to 20%: enhances thermal resistance, surface hardness and dynamic performance; typical color beige.

Featured Benefits for Parts

• Improved hardness and dimensional stability for load-bearing or precision components.
• Ability to tailor electrical or thermal conductivity by selecting conductive fillers.
• Enhanced tribological performance (lower friction, higher wear resistance) using solid-lubricant or metal fillers.
• Wide range of appearance and color depending on filler type and loading.

Technical characteristics / specifications
