The Composite Division of TecnoCaucho Rolls & Covers offers most advanced technology in composite covers, as well as most advanced technical and human resources that give us the experience and quality of the best manufacturers of composite covers for rolls at a world-wide level.





We have a Composite Laboratory and experienced technical staff, which allows us to develop made-to- measure coatings of Composite, even Conductive or Antistatic Composite Covers.


Our main Composite Coatings are the following:




Nanorock

It is a Composite Cover developed to withstand the most demanding work conditions, like Hard Press. This Coating is recommended for the following positions of the Paper Machine:


Hard Press rolls of Press Section

Hard Press of Size-Press

CCRoll Shoe Press

Central Press



layer thickness

12,5 - 15 mm.

hardness

88 - 92 Shore D

usable layer

5mm. (recommended) 7mm. (depending on the working conditions)

finish

<0,4 µm

top service temperature

150 ºC

junction zone top temperature

150 ºC

top lineal load

550 KN/m.

top loading frequency

25 Hz




Nanotec

Due to its highest quality and technology, it is the top solution in Composite Covering for Rollers. Designed to withstand the most demanding working conditions in the Calender sections of the Paper Machines (Paper mills?) The Nanotec cover is especially recommended for Soft Calender Presses of the following types:


Soft Calender

Super Calender

Multinip Calender

Mat-on-line Calender


The Nanotec Composite Cover offers a very low porosity, therefore allowing us to achieve exceptional finishes, which along with the highest wear resistance allows to keep the Calenders in service for a longer period of time, without needing frequent grinding operations.

The raw material used as well as application method allow us to offer exceptional finishing qualities without any superficial differences or texture alterations that could later appear on the processed paper.

Composite Grinding Detail

The perfect finish and grinding of the composite covered press rolls are indispensable for its correct operation and taking advantage of all the qualities that these composite materials offer to us. In Tecno-Caucho Rolls & Covers we have the knowledge as well as the most advanced and modern Composite Press and Roller Grinding machinery.
