Polymer beads

For the manufacture of cosmetics, we produce a highly refined grade that is low in impurities and residual monomer.
We provide fine particles of polymethyl methacrylate, polystyrene, silicone, and polyurethane.
When added to foundation, lotions etc, it improves feel and spreadability. 
We also have types such as those shown below as characteristic grades.

1. Readily water disperse type
2. Porous type
3. Non-spherical type
4. Soft type (acrylic, silicone, polyurethane)

"By utilizing the difference between the refractive index with the matrix resin, refractes light at the interface and shows light scattering effect.
Excellent dispersion on the resin and heat resistance (meaning thermal decomposition and thermal yellowing)."
We can modify the following property.

1. Refractive index control (1,410-1,590)
2. Average particle size control (2~100μm)
3. Particle size distribution (control of fine and coarse powder)
4. Particle construction control (porous, core and shell multilayer construction)

It's possible to give the design (matting and patterning) by adding to paint.Excellent solvent resistance and dispersion performance to the paint.
There are general hard type (PMMA) and soft type which is excellent scratch resistance (PBMA and polyurethane).
There are also a porous type which is excellent matting in addition to general true spherical type.
For the case that is added in water-based paint, an arrangement in the type of wet powder(moisture content 10~20 percent) is possible.

This is a grade listed in Appendix 1 and Appendix 2 (Additives) found within the positive list program for food utensil and container packaging run by Japan's Ministry of Health, Labor and Welfare.
Excellent dispersion on the resin and heat resistance (meaning thermal decomposition and thermal yellowing).
There are also grades wherein die drool (which is a problem during the membrane production of polyethylene film) occurs infrequently.

These can be used as pore-forming agents which adds small cavities (pores) to molded items by mixing them and undertaking a high-temperature calcination process.
It offers excellent thermal decomposability and is characterized by low levels of residue after the calcination process.
Small cavities (pores) with stable sizes can be added since particle sizes are uniform.

1. Synthesis of particles with shape characteristics is also possible.

1. Synthesis is also possible for core-shell structure particles.

• Spherical and smooth surface.
• Possible to add slippery properties.

• Porous shape with unevenness in the surface.
• It is possible to improve adhesion in relation to resins thanks to the anchoring effect provided.
• Customers can expect improvements in terms of optical scattering properties as a result of the uneven structure.

• Provides a soft feel that is derived from the rubber layer.
• Structure featuring easy tracking on changes such as stretching.

Changing various properties is possible through the selection of various resins and the copolymerization of acrylic monomers.

1. Softness of the resin
   Customers can expect improvements in terms of the feel and positive effects in terms of the prevention of abrasion.
2. Solvent resistance
   Customers can expect reductions in terms of viscosity change when adding elements to various solvents.
3. Heat-resistance (thermal decomposition)
   By changing the resin's structure, you can change the temperature at which thermal decomposition starts.
   Customers can expect reductions in terms of thermal decomposition and thermal yellowing when kneading at high temperatures.

Thermal decomposition behavior of acrylic-type fine particles

1. Refractive index (1.410 to 1.590)
   Control of the refractive index is possible by performing adjustments to the resin structure.

1. Fine particle refractive index: 1.55
2. Fine particle refractive index: 1.53
3. Fine particle refractive index: 1.49
