Nitrile Rubber Bonded Cork Sheet for Transformer - CR105
CR105
nitrile rubber bonded cork sheet is really a high performance rubber
articles cork designed specifically for electronic equipment sealing.
This kind of specialised rubberised cork gasket sheet is made of a
specialised Nitrile rubber (NBR) put together with smaller cork
granules.
Nitrile
rubber bonded cork sheet is tremendously appropriate for most common
transformer liquids and exhibits fantastic compressive energy, strength
as well as flexibility. Additionally, it has good electronic insulation
properties as well as is very tough. The thickness for the cork rubber
sheet can be 1 mm, 1.5mm, 2mm, 3.2mm, 4.8mm, 6.4mm and 9.5mm thick,
width as customers' want.
Features of NBR Bonded Cork Sheet
NBR Bonded Cork Sheet is the good quality cork sheet created using a
great portion of Nitrile rubber and cork granules. And is perfect for
making cork gaskets and seals for transformers and power equipment.
Appropriate for most transformer oils at temperature nearly 125°C. This
specific higher percentage of nbr nitrile rubber assure this particular
cork sheet features very excellent elongation (100% max.) and
compressive strength (surpasses 70 MPa). It provides a shore durometer
hardness of 70 Shore A along with a broad sealing stress range (3 MPa to
20 MPa).
Application of Nitrile Rubber Bonded Cork Sheet
Nitrile Rubber Bonded Cork Sheet is made by us Kaxite along with used
all around the world. By far, the most popular application for CR105 is
producing cork gaskets and seals for transformers as well as electric
equipment. Additionally it is used for making electrical bushings and in
several applications beyond the electrical industry which include
tubing support liners and general-purpose cork gasket.
