Expol heat-shrinkable End caps are made of high quality and technics. It is cross-linked materials therefore non melting and resisting to cold flow.
End caps are coated inner wall by poly-amide bonding.
When it heated flow the bonding become absolutely water-proof. End caps are suitable for a protection of power and glass-fiber cable end.
*Material
CAP:Modified Cross Linked Polylefin
Outer Color:Black
Resistant to most organic and nonorganic solvents. Resistance to other specific chenmicals on requsts.
INTERNAL COATING:Plymade Adhesive The adhesive bond show excellent characteristics, even at law temperature
*Applications
' Application range:110 to 9mm diameter
' Working temperature:Max. 125¡É
' Cable termination system for protecting cables from the ingress of moisture during storage transport and installation work.
' Surge-proof cable connection of the live cable for telecommunications use
