Liquid Silicone Rubber LR-LSRCA

Liquid silicone rubber LR-LSRCA is a LSR for cable accessories which is a type of high-voltage-resistant liquid silicone rubber with a two component platinum-catalyzed system, using a 1:1 A/B ratio. Component A is transparent, while Component B is gray.

It’s suitable for injection molding, with high tensile strength, excellent elongation, strong tear resistance, low compression set, rapid curing time, and compliant with RoHS and REACH certifications.

Test :130°C x 10min,200°C x 4H.

Application: 

Medium-voltage cable accessories, internal and external cold-shrink terminations, transition joints, and sheathing.


Package &Storage:

In 20kg or 200kg drum.

Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, shelf life is 12 months from the date of production. It is shipped as non-hazardous substance.

Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
