Research & Development

RPF's friction products are designed, manufactured and tested with attention to every detail, from matching the right friction material to the application through the production of raw materials and to final assembly. Thousands of hours of research and dynamometer testing are applied to ensure that Ratek friction discs are the best you can get (Exactly what you need).

  • Qualified Design Engineer. Well trained in Brake and Clutch application
  • Used advanced facility of CAD, CAM, FEA.
  • Advanced Brake Dynamometer with Trailer Load Simulation
  • Own formula for friction paper formulation w.r.t each application


RPF has a wide range of Friction Materials which have been developed and tested In-House. Broad Categories are as below :

Constant engagement with OEMs and a detailed Market Analysis, assist RPF to focus on New Product Technologies and be the First To Market. RPF and its engineers with their experience have the capability of Designing Friction Material and Solutions for the Customer. All Friction Material are tested on a Computerized Testing Machine which was designed by RATEK. Thus enabling us to have full control on the Performance Parameters like Co-efficiency, Stability, Vibration, Heat Resistance and Wear Resistance.

Example of Friction Facing Information Sheet

A greenish-gray composite resillent organic or 'paper' type material, designed for use in wet or oil-immersed applications.

This material has a moderately high coefficient of friction and reasonably well-controlled static-to-dynamic friction. It also exhibits excellent wear resistance when used in appropriate applications.


  • Moderate to high energy range clutches
  • Static holding brakes
  • Moderate energy direct clutches
  • Low to moderate energy positioning brakes and retarding or 'drag' brakes (with proper forced cooling)

(in typical automatic gearbox fluids)
Dynamic Coefficient :0.125 - 0.14
Static Coefficient :0.11 - 0.15
(lock to slip condition)
Facing Pressure :Less than 3.0 MPa
for dynamic conditions
Less than 5.5 MPa
for static conditions
Values are approximate and may vary in specific
applications and lubricants.
