A Look Into Promerus' Top Materials for Electronic Appications

Promerus pioneered the catalyst technology that enabled addition polymerization of polynorbornenes (PNB). PNB is a class of cyclic olefin polymers (COP), which maintains the bicyclic ring structure in the backbone without the use of non-bicyclic comonomers. This allows the PNB backbone to remain rigid, resulting in glass transition temperatures (Tg) that are quite high, even >300 ̊C.

Unlike polyimides, which stiffen as they cure via ring-closing mechanism releasing volatile components at elevated cure temperatures, PNB does not require high cure temperatures in order to achieve a high Tg. Additionally, the ability to maintain high thermal characteristics with glass-like transparency is unique to the industry.

Furthermore, we can copolymerize a wide variety of norbornenes with functional groups (for adhesion, elongation, etc.) to tailor the PNB polymer to meet customer requirements. Through this unique ability to tailor PNB polymer compositions, we’re able to adjust the properties of our materials, while maintaining transparency across a broad spectrum of wavelengths.

Advances in 3D printing are enabling technology for a wide range of applications.

Nowadays, many things around you are built with the help of a 3D printer. This is because designers, engineers and manufacturers can experiment with numerous design iterations at no extensive time or tooling expense.

But, not all 3D printers use the same materials. In fact, the material often dictates what 3D printing processes are available to use.

Below, we explore the various types of materials, including metals, photopolymers and thermoplastics.

According to ScienceDirect, “Photopolymerization is a technique that uses light (visible or ultraviolet) to initiate and propagate a reaction to form a linear or cross-linked polymer structure.”

It’s a significant area of focus for researchers and developers, as it allow for production of materials with customized properties.

In microelectronics, for example, scientists are able to manipulate the physical properties of polymer networks to improve adhesion and solvent resistance by exposing the material to light sources.

If you think that’s impressive, continue reading for three other interesting photopolymerization applications.

The microelectronics industry is undergoing a transformation. 

Today’s engineers are challenged to create lighter and thinner designs with high-performing components that meet the requirements of specific applications. 

According to Functionalized Polynorbornene Dielectric Polymers: Adhesion and Mechanical Properties, “Polynorbornenes exhibit the key performance criteria for these demanding applications.” However, an un-functionalized polynorbornene exhibits poor adhesion to common substrate materials used in integrated circuits.

This is where functionalization comes in.

But first, what is a norbornene? What is a polynorbornene? Continue reading below to find out.
