What is phenolic resin used for?

Phenolic resins are found in a myriad of industrial products. They are mainly used in the production of circuit boards. They are better known for the production of molded products including billiard balls, laboratory countertops, and as coatings and adhesives.

There are two main production methods. One reacts phenol and formaldehyde directly to produce a thermosetting network poiymer, while the other restricts the formaldehyde to produce a prepolymer known as volcano which can be moulded and then cured with the addition of more formaldehyde and heat. There are many variations in both production and input materials that are used to produce a wide variety of resins for special purposes.

Resol resins are phenol-fomaldehyde thermoset resins obtained under base catalist conditions. Depending on resin structure, a variety of properties can be achieved.

Novolac resins are phenol-fomaldehyde thermoplastic resins obtained under acid catalist conditions that cannot react further without the addition of a cross-linking agent.

SBHPP novolac resins are supplied both in liquid or solid form with and without curing agent. We offer various types of phenolic novolac resins which have high heat resistance, water resistance, chemical resistance, high strength and other functionality.
