CL Series FLO-BEADS feature a superb feel due to their

excellent particle size distribution and perfectly spherical

shape, making them ideal for cosmetics.

CL-2080 is often used in cosmetic foundations.

Low-density polyethylene(LDPE)

High-density polyethylene(HDPE)

HE Series FLO-BEADS are fine particle of high-density

polyethylene Featuring excellent heat resistance.

FLO-BEADS EA -209 regards ethylene acrylic acid

copolymer as raw materials.

Because I have a carboxylic acid radical in a molecule,

FLO-BEADS EA -209 shows a hydrophilicity and shows

affinity with the polarity compound.

Ethylene-acrylic acid copolymer(EAA)

Ethylene methyl methacrylate copolymer(EMMA)

FLO-BEADS SE(SOFT-BEADS) are made from ethylene

methyl methacrylate copolymer resin.

FLO-BEADS SE have an urethane particle and the equal

above-mentioned particle softness more softly than

FLO-BEADS.

Heatproof height of HE-3040 facilitates processing. EA-209 and SE-3107A(3207B) that has a soft feeling is weak to heat. Therefore, attention is

necessary for handling.

garments

Specific leaf area ,Oil absorption

The ratio surface area is big

Not the difference by the resin class

A difference by the difference of resin properties of

matter (a functional group)

Solvent resistant(Raw materials resin)

I make a seat of the raw materials resin and leave a dip to various solvents.

It is evaluated the weight change of the seat as swelling magnification (%) afterwards.

Evaluation standard

◎:Weight rate of change less than 5%

○:Weight rate of change 6~15%

△:Weight rate of change 16~30%

×:More than weight rate of change 31%

The tolerance of HDPE that confronts oil used with cosmetics in general is high.

On the other hand, it is necessary to note oil that the tolerance to oil uses enough as for EAA and EMMA.

Particle hardness

I compress about 10μm beads and measure the compressive strength at the point in time when 10% were displaced

FLO-BEADS is a particle that is softer than PMMA and Ny.

Especially, FLO-BEADS SE is the more same compared with the urethane or soft particle any more.

Specific gravity control

Particle surface treatment Specific gravity adjustment is free

I control particle dispersibility

Applied technology: Surface reforming

With an inorganic matter, organic matter and a color, I can perform reforming and composition and the coloration of the

particle surface easily.

The feel and particle specific gravity and the reforming of the optics characteristic and various function grants and reforming

of design characteristics that said that I matched with user needs by using these particles are possible.

Applied technology: Surface reforming

FLO-BEADS surface-treated with talc, etc. are used in cosmetics as a foundation material

that has an excellent feel and provides a material regulate effect.

Talc oating

FLO-BEADS surface-treated with titanium oxide are used in cosmetics as a foundation

material that has an excellent feel and provides an ultraviolet shielding effect.

TiO2 coating

Organic materials are used to modify the surface of FLO-BEADS to produce fillers for

cosmetics and toiletry prducts.

PMMA coating
