What is a functional raw material?

For example, it is a compound with a skeleton that exhibits performance such as improved heat resistance and high refractive index.

Characteristics of a functional raw material

It is beginning to be used as a material for information technology and electronics as the naphthalene skeleton is highly sensitive to heat and light.
It has expectations as a resin raw material as the naphthalene skeleton is expected to improve heat resistance.
Acrylate derivatives with a naphthalene skeleton are expected to have a high refractive index.
It has expectations as a raw material for various derivatives (various resins, heat-resistant resins, pharmaceutical and agricultural chemical intermediates).

Differences from others

It is a functional raw material (diol) that has the potential to exhibit unprecedented performance, such as providing a resin that has better heat resistance than phenol and bisphenol A and has a high refractive index when made into an acrylate derivative.

Recommended for...

Those who want to achieve heat resistance

It is expected that heat resistance will be improved by introducing the naphthalene skeleton.

Those who want to attain resins with high refractive index

We have confirmed that acrylate and methacrylate resins with the naphthalene skeleton have a high refractive index. We expect to develop resins with a higher refractive index than before by blending.
