Silicone tube for corona machine

Dongguan Yutian more than 28 years of production management experience, only to provide customers with high-quality corona silicone tube, corona silicone tube is also known as spark machine, discharge rack, spark rack silicone tube, etc., this kind of accurate keyword name is also the annual new product of silicone extrusion, its advantage is that the size breaks through the traditional corona silicone tube can be more than 200mm size, And can work normally at high temperature for a long time.

Product Features

Silicone tube is widely used in high temperature machinery, roller heat dissipation

Size from 1~200mm can be produced, no collapse and no eccentricity

Bending resistance is not easy to deform, with good holding force and shrinkage

Excellent high temperature resistance, long-term temperature resistance within 300° range

Stable fatigue life, suitable for high-intensity work

Color size can be customized production by drawing and sample

product description

The main characteristics of the silicone tube are high temperature resistance, fatigue resistance test these two core indicators, from the production point of view is that its size is large, generally need to do 100~250mm this size range, so these two indicators have limited a lot of silicone tube extrusion manufacturers, The problem of the size of the silicone tube is that it requires a large extrusion vertical mechanism and the market of this equipment is relatively small, so most enterprises can not manufacture, and Dongguan Yutian with new technology and new machines can currently achieve long-term orders of the silicone tube of the size below 250mm. The raw materials of the silicone tube are divided into ordinary materials and high temperature resistant special raw materials. If the roller will continue to produce high temperature power generation if it works for a long time, it is necessary for the silicone tube to play the role of heat insulation power generation. Ordinary silicone can only withstand the temperature below 200°, and can not contact the temperature above 200° for a long time. If the customer uses the corona machine is not a long time of work, it can use ordinary plastic silicone tube of the corona machine, on the contrary, it needs to be made of high-temperature special materials, on the premise of these two core indicators has stumped many companies, in addition, the roller size of the corona machine is large and the silicone tube needs to be set on its surface to play a role in generating heat insulation. If you want to cover the silicone tube, you need to expand the treatment generally need to expand more than 1 times to cover the roller, and after the cover of the roller, you need to tightly hold the roller can not be loose, which requires silicone to have good contraction performance.
