Medium and high votage resistance LSR insulator
1) Basic model:LIM2930A/B and LIM2945AB
2) Product Description
2-part liquid silicone rubber,which is suitable for injection
or extrusion molding with tracking resistance 1A 3.5 grade,
mixing ration of parts A:B=1:1,withstanding middle and
high voltage, catalyzed by platinum .The appearance of A
is transparent and B is gray.
3) Key Features
Outstanding anti-ageing
High elongation and low tension set
High tear strength
Excellent tracking resistance
Excellent electric performance
Rapid vulcanization
4) Applications
Indoor cold shrink and terminal, tie-in and jacket etc suitable for injection and extrusion molding
Medium and high voltage resistant cable accessories.
5) Storage
Correctly stored in its original closed container at room temperature (max 30). SQUARE® LIM2930/2945AB has a shelf life of 12 months. The ready to use LIM2930/2945AB should be kept tightly closed, if doesnt , it will affect the shelf life.
6) How to use
Ready-to-use mixturescomponents A and Bare fed directly to injection molding machine from the original containers by means of a metering end mixing unit called static mixer The mixtureat the mixing ratio 11 is injected into the heated mould. The shelf life is 7 days (23°C) after mixing. The pipline should be cleared if the machine wont work for long time.
7) Packaging
SQUARE®LIM2930A/B and LIM2945A/B are available in 20kgs pails or 200kgs drums.
