Powdered Novolac Phenolic Resin Low Free Phenol for Friction Materials

Product description

An acidic catalyst and aThe final novolac resin is unable to react further without the addition of a cross-linking agent.  The resins having the curing agent incorporated cure or "thermoset" to the desired degree when processed by the customer. The most common phenolic resin cross-linking agent is hexamethylenetetramine, also known as hexa, hexamine, or HMTA. Ground and blended with the resin, hexa serves as a convenient source of formaldehyde when heated to molding and curing temperatures.

 

Application

 

Powdered Novolac Phenolic resin is the choice for composite friction materials: the pads, blocks, linings, discs and adhesives used in brake & clutch systems that create retarding or holding forces with application against a moving part. The inherently heat resistant phenolic resin carbonizes and chars at extreme service temperatures, it does not melt and smear like other polymer matrices. This property results in restored friction properties when the material cools and "recovers" from hard braking.
