PRODUCT
DESCRIPTION :
Silopren®
HV 2/2160 is a heat cure silicone rubber
base compound that was especially designed
to meet the requirements of the wire and
cable industry. Its most conspicuous features
are therefore ease of processing, good electrical
properties, and improved hot-air resistance.
KEY
PERFORMANCE PROPERTIES
• Good extruding processability (High
Green Strength)
• Good mechanical profile
• High level electrical properties.
• Enhanced high temperature resitance.
• Filler extendable.
