Apr 23, 2017 · The added functionality of the phenolic resin increases the ability for the resin to crosslink, creating a stronger polymer with high resistivities. A common type of epoxy phenolic resin is epoxy phenol novolac, in which the phenolic resin is a phenolic novolac resin, consisting of short polymers between 10-20 repeating units.

Base-catalysed phenol-formaldehyde resins are made with a formaldehyde to phenol ratio of greater than one (usually around 1.5). These resins are called resoles. Phenol, formaldehyde, water and catalyst are mixed in the desired amount, depending on the resin to be formed, and are then heated.

4.4 Polybenzoxazine-Epoxy-Phenolic/MWNT Nanocomposites. Rimdusit and Ishida reported a polybenzoxazine copolymer based on epoxy and phenolic resins [32]. The epoxy resin served as a reactive diluent to reduce the viscosity of the mixture and provided a higher cross-link density, which led to improve thermal stability.

Hexion offers one of the industry’s broadest lines of epoxy curing agents, including phenolic resins, to satisfy a range of performance needs. Friction Materials Bakelite phenolic resins, because of their high heat properties, are used in friction applications for the automotive and rail industries.
An epoxy phenol novolac (EPN) is an epoxy resin where the epoxide functional group is attached to the phenolic oxygen of a phenolic novolac. As such, each phenol oxygen of the novolac resin is attached with a –CH 2-(C 2 H 3 O) group, where -(C 2 H 3 O) is a three-membered epoxide ring.

    Mar 07, 2018 · Phenolic resin is ideal for lab environments where contamination is a key concern. Phenolic resin is oil and moisture resistant, as well as resistant to most bacteria and fungus. As with epoxy, phenolic resin is optimal for environments working with high heats (up to 350ºF/ 176ºC).

  • Epoxy vs Phenolic: How Are They Made? While both of these laboratory surfaces are resin, they differ in the way they are constructed. Namely, phenolic resin countertops are made in layers. These countertops are manufactured by layering kraft papers that are saturated in resin. A heat-intensive process forms them into a solid product.
