Overview

Nano sized spherical polymer particles with a hollow interior.
Supplied in solvent dispersions to preserve nano-sized particles in primary particle form.

Fine particles

Features

  1. (1) Nano-sized particles with a uniform particle size distribution can be added to materials to produce highly transparent and low refractive index coating.
  2. (2) Particles blend well with organic solvents and resin coatings due to the composition and provides excellent dispersion.
  3. (3) The NH series compared to inorganic hollow particles will add more optical properties due to the weight of the particle being lighter and concluding with more particles within the same weight concentration.
  4. (4) High affinity with the coating prevents cracking when films are bent or cut out.
  5. (5) Other than having a low refractive index, the hollow structure is expected to reduce weight, heat insulation, and permittivity properties.

Low reflection comparison

The particles applied in the coating reduced the reflection of the film due to decreasing the refractive index of the coating.
For comparison, the low reflection coated film was placed on the right side of the show case surface containing the cups.
The reflection from outside the case was low and the image of the cup is clearer. An example of this functionality is being able to see the TV clearer when a low reflection film is added to such display.

Comparison

Strength comparison of the coated film

The organic binder and TP-NH had high compatibility according to the composition of the particle concluding with excellent bending resistance.

Comparison

Others

The particle size, density, type of solvent dispersion is adjustable to your requirements.

Cosmetic ingredients

Grades with residual monomers removed by advance purification processes are available for cosmetic applications. The spherical shape of the “TECHPOLYMER” can improve spreadability of foundations, create a soft-focus effect, and change the texture. Porous particles that can be used as adsorbents, and elastic particles that adds soft feel are also available.

Particle Size Control

“TECHPOLYMER” is available in the size from submicron, micron, and up to millimeter* sizes. The wide product range offers the most suitable size for your application.
* The millimeter sizes are available as a separate product called the “DUOMASTER”.

Particle Shape Configuration

We have successfully established shape configuration technology which enables the control of interior and exterior structure of the particles to develop non-spherical particles, hollow, and porous particles. Non-spherical particles are expected to obtain special optical properties from the special shapes in applications. The porous and hollow particles improve properties such as light diffusion, low permittivity, absorption. These particles are lower specific density according to the air voids within the structure.

Porous Structure

Hemispherical

Composition Variation

Sekisui Kasei has developed various new “TECHPOLYMER” grades that offer new functions and features. We can also develop custom grades for Customer’s special needs. Please contact us to discuss your applications.

Particle Characteristic Control

“TECHPOLYMER” offers a wide range of grades with the properties controlled to suit various applications. For display applications (liquid crystal), many grades are offered by adjusting the refractive index of the particles in order to obtain the desired light diffusion effect. For paints and coatings, various grades are being used in which the hardness of the particles has been adjusted to improve the texture of the coating.

Stability Improvement

“TECHPOLYMER” grades to withstand harsher conditions with higher resistance are available.
Contributes to higher productivity and quality stability of the final product enabling a wider choice of material to use.

Functionality Improvement

Developing high functionality particles by compositing “TECHPOLYMER” with other functional materials.
Other than the functionality of the material, the following are expected from composited particles.

  • Improvement in handling

  • Improvement of dispersibility in the matrix

  • Reduction in the amount of additives

In addition, particles with the characteristics of both the “TECHPOLYMER” and the functional material can be created such as the following:

  • Anti-blocking property (“TECHPOLYMER”) and conductivity (conductive material)

  • Light diffusion (“TECHPOLYMER”) and wavelength control (wavelength control material)

  • Impact resistance (“TECHPOLYMER”) and conductivity (conductive material)
