RESITEL®
É Polyurethane Resins BLOCKING
|
|
PRODUCT INFORMATION
Advantages
over other Polyurethane systems:
-
Low tension up to high hardness
- Better
resistance to water permeation (including water vapor)
- Better
hydrolytic stability
- Better
absorption to sound and impact
- Improved
handling properties (low sensibility to moisture, therefore
less gassing)
- Low
viscosity, excellent adhesion, chemical resistance
- Excellent
electrical properties
- Easy
to mix, cured at room temp
- Excellent
tensile strength properties
-
Low heat emissions during cure, low shrinkage (therefore does
not affect equipment sensitive to pressure and temperature)
These
resins do not corrode in contact with copper and are compatible
with all materials that are mostly used in electric equipment.
RESITEL
resins have been widely accepted in Telecom and E/E industry.
Most
frequent applications are: pressure blockage and telephone cables
splicing, voltage regulators, transformers, capped cables, circuit
covers, transistorized ignition systems and impact absorbers

RESITEL® 003
Pressurization Blocking
|
Differs from
Resitel 001due to its higher hardness linked to a lower viscosity.
This allows a better flowability in cables of plastic lining.
