POWERSIL®466 A/B LV
Electrically Conductive Liquid Silicone Rubber
Characteristics
POWERSIL®466 A/B LV is a liquid silicone rubber with medium conductivity, and excellent mechanical properties.
Special Characteristics
• High elongation at break, low tension set
• Stable electrical properties
• Very good mechanical properties
Application
POWERSIL®466 A/B LV is suitable for production of electrically conductive moulded articles, especially cable accessories in the medium and high voltage range. The range of use spreads from push-on accessories to cold shrink applications. POWERSIL®466 LV com-bines a low Shore A durometer with high elongation, good setting properties (low tension set) and good mechani-cal properties which are a must for cold shrink applications.
Processing
Components A and B are delivered ready to use in drums of 20 and 200 litres capacity. They can be pumped by means of standard metering equipment from these drums straight into the injection moulding machine and be mixed in a static mixer. The mixing ratio is 1 : 1.
At room temperature, the mixture of A and B compo-nents has a pot life of about three days.
For detailed information, refer to our brochure "ELASTOSIL®LR Liquid Silicone Rubber - Properties and Processing".
Storage
POWERSIL®466 A/B LV has a shelf life of at least 6 months when stored between 5 °C and 30 °C 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 intended use must be checked for quality as-surance reasons. The “Best use before”- date of each batch is given on the product label.
If the material is kept beyond the recommended shelf life, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
Safety information
Comprehensive instructions are given in the corre-sponding Safety Data Sheets. They are available on request from our Wacker subsidiaries.
