Long Flow Novolac Phenolic Resin Pellet for Electronic Molding Compound

Product description

Novolac Phenolic resin (two-step) is produced by condensing phenol with an insufficient amount of formaldehyde to complete the reaction in the presence of an acid catalyst. This produces a thermoplastic resin. To cure this resin, a hardening agent is used, HMTA (or hexa). Under heat and pressure, it yields ammonia and formaldehyde as methylene groups to cure the resin, hence the term “two-step,” because of the two formaldehyde additions. A novolak phenolic resin has an infinite shelf life under normal storage conditions.Cured phenolic resin provides the rigidity necessary to maintain structural integrity and dimensional stability even under severe conditions.

Application

Novolac Phenolic Resin P8211 is recommended for epoxy curing agents,especially for epoxy system users seeking high glass transition temperature (Tg), excellent stability at high operating temperatures, superior flame retardancy, and overall mechanical integrity
