Product List
- Magnet Wire - Insulated Single Conductor
PUR
PES
PEI
PEI-AI
PAI
PUR
The conductor, copper or aluminium, is insulated with crosslinked polyurethane that forms an even, seamless coating over the conductor.
PUR can be supplied in various diameters with one (1) or two (2) coatings normally designated PUR1 and PUR2.
APPLICATIONS
Radio frequency coils
Relay coils
Measuring instruments
Small motors
Solenoids
Small transformers
Miniature coils using ultra fine wire
PROPERTIES
Temperature Index on Copper 130ºC (Class B)
Excellent dielectric strength heat shock of >140ºC
Very low dissipation factor, remaining reasonably constant at high frequencies or under humid conditions
No mechanical or chemical stripping required
Able to be manufactured with very close diameter limits
LIMITATIONS
Insulation properties downgraded over 200ºC
Prone to hydrolysis if used in hermetic systems or encapsulations when in the presence of cellulosic materials or moisture
Prolonged contact with aggressive solvents (e.g. keytones, alcohol) may cause enamel softening
Adequate ventilation required when tinning or soldering

Data Sheet
PES
PES is manufactured in a similar manner to PUR, however a small amount of polyimide is added to the enamel so that the temperature index is improved without reducing the solderability.
APPLICATIONS
Encapsulated Coils
Relay Coils
Small Motors
Solenoids
Transformers
As a Solderable base for heat bond enamel

PEI
PEI is a polyester imide coated wire that is the most common wire used in Australia today for the electric motor repair
APPLICATIONS
High Performance Motors
Large relays
Any application where periodic exposure to temperatures up to 200ºC occurs.
Transformers
Choke Coils
PROPERTIES
Temperature Index on Copper 155ºC (Class F)
Thermoplastic flow temperature not less than 320ºC
Smooth Glossy surface finish
Chemically very stable, resists extraction with R22, methanol trichloroethylene and perchlorethylene
