POWERSIL®732 CS
Liquid Silicone Rubber
Characteristics
Liquid silicone rubbers of POWESIL® series are paste-like, easily-pigmentable two-component compounds with short curing times. Their vulcanisates are noted for their excellent mechanical and electrical properties .POWERSIL®732CS is optimized for cold shrink applications.
Special characteristic
l Outstanding dielectric properties
l Excellent mechanical properties
l High tracking and arc resistance
l Excellent hydrophobic properties
l Very easy to process.
Application
l Cold shrinkable cable accessories
l Outdoor and indoor use
Processing
The A and B components are delivered ready-to-use in 20 I and 200 I drums. With standards metering equipment , the products can be pumped directly from the original containers into the injection moulding machine and mixed in a static mixer. The mixing ratio is 1:1
Storage
POWERSIL®732CS has a shelf life of at least 6 months when stored between 0℃ and 30℃ in the originally sealed container .The best use before end’ date of each batch appears on the product label .
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however , the properties required for the intend use must be checked for quality assurance reasons.
Safety information
Comprehensive instructions are given in the corresponding Safety Data Sheets .They are available on request from our Wacker subsidiaries
