PTFE raschig ring can be made by virgin PTFE (100% pure PTFE) or
PTFE with graphite, or with fiber glass etc.

TEFLON  

CODE #	CONSISTS OF	DEFINITION OF FILL
TEFLON 101 TEFLON  102 TEFLON 103 TEFLON  104 TEFLON  105 TEFLON  106	5% Glass Fiber 10% Glass Fiber 15% Glass Fiber 20% Glass Fiber 25% Glass Fiber 30% Glass Fiber	Milled glass fibers have the least effect on chemical and electrical properties and add greatly to the mechanical properties of unfilled PTFE. Addition of glass improves compressive properties by as much as 40% and improves wear resistance greatly. These compounds resist acids and oxidation but can be attacked by alkali.
TEFLON 110 TEFLON  111 TEFLON  112 TEFLON  113 TEFLON 114	5% Graphite 10% Graphite 15% Graphite 20% Graphite 25% Graphite	Graphite has good chemical resistance to corrosive environments and exhibits good initial wear and rubbing/sliding characteristics in dry and water applications. Commonly blended with carbon and PTFE.
TEFLON  115 TEFLON  116 TEFLON  118	25% Bronze 40% Bronze 60% Bronze	This filler has better wear, creep resistance, and higher thermal conductivity than glass fiber with PTFE. The compound is easily machined, but has poor chemical resistance in the presence of acids and alkali. Useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat.
TEFLON  127	5% Molybdenum Disulfide	This filler is used frequently in combination with others to increase surface hardness, stiffness, and to reduce the starting coefficient of friction and steady-state wear. Its effect on electrical and chemical properties is negligible.
TEFLON  130 TEFLON  131 TEFLON  132 TEFLON  133 TEFLON  134	5% Carbon 10% Carbon 15% Carbon 20% Carbon 25% Carbon	Carbon has good chemical resistance to corrosive environments. It exhibits good initial wear and rubbing or sliding contact characteristics, both dry and water applications. It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surfaces.
TEFLON 136 TEFLON  137 TEFLON  138	10% Carbon-Graphite 20% Carbon-Graphite 25% Carbon Graphite	These fillers are used both separately and together in PTFE compounds.
TEFLON  140 TEFLON  141 TEFLON  142	5% Calcium Fluoride 10% Calcium Fluoride 15% Calcium Fluoride	ALTERNATIVE TO GLASS FILL.
TEFLON  151 TEFLON  152 TEFLON  153 TEFLON  155	15% Glass Fiber, 5% Moly 20% Glass Fiber, 5% Moly, 5% Carbon-Graphite 23% Glass Fiber, 2% Moly 25% Glass Fiber, 5% Moly	SEE ABOVE FOR INDIVIDUAL DEFINITIONS.
TEFLON  157 TEFLON  158 TEFLON  159	10% Glass Fiber, 10% Graphite 5% Glass Fiber, 5% Graphite 20% Glass Fiber, 5% Graphite	SEE ABOVE FOR INDIVIDUAL DEFINITIONS.
TEFLON  161 TEFLON  162	10% Glass Fiber, 5% Carbon 5% Glass Fiber, 10% Carbon	SEE ABOVE FOR INDIVIDUAL DEFINITIONS.
TEFLON  170 TEFLON  171 TEFLON  172 TEFLON 173	40% Bronze, 5% Moly 40% Bronze, 10% Moly 55% Bronze, 5% Moly 65% Bronze, 5% Moly	SEE ABOVE FOR INDIVIDUAL DEFINITIONS.
