1) Basic model:LSR1510-45A/B.LSR1510-35A/B.
2) Product Description
2-part liquid silicone rubber,which is particularly suitable for injection molding with tracking resistance 1A 3.5
grade, mixing ration of parts A:B=1:1,catalyzed by platinum.The appearance of A is transparent and B is grey.
3) Key Features
Outstanding anti-ageing
High elongation and low tensile set
High tear strength
Excellent tracking resistance
Rapid vulcanization
Injection molding
4) Applications
Indoor and outdoor cold shrink terminals
Medium voltage cable accessories
Cable connectors
5) Storage
Correctly stored in its original closed container at room temperature (max 30). SQUARE® LSR1510-35A/B LSR1510-45A/Bhas a shelf life of 12 months. The ready to use LSR1510-35A/B LSR1510-45A/B should be kept tightly closed, if doesnt , it will affect the shelf life.
6) How to use
Ready-to-use mixturescomponent 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®SR1510-35A/B,LSR1510-45A/B are available in 20kgs pails or 200kgs drums.
