Lightweight and non-scattering additive

We are sure that EMC is very helpful, taking an important role not only as a lightweight material but also as a functional filler in every stage.

EMC

Features of EMC

EMC is a lightweight filler with good handling while taking advantage of the unique properties of plastic microspheres.
Unlike other inorganic hollow fillers (such as glass balloons), it has excellent elasticity, pressure resistance, and heat insulation.

Excellent elasticity

EMC deforms when pressure is applied and returns to its original sphere when pressure is removed.
Please press EMC in a sample bag with your fingers firmly.
It never collapses.
Rather, you will understand the elasticity of EMC due to which it is pushing back.
Due to the excellent elasticity of its particles, there is little crushing or cracking during processing, which results in stable quality after mass production.
In addition, Spray Painting can apply without the particles being collapsed.

Excellent pressure resistance

EMC can withstand considerably high pressures. In our tests, it withstands even a high pressure of 25Mpa x 30min. On the other hand, microspheres consisting of inorganic hollow particles (glass micro balloons) have glass outer shells, so the balloon itself is not elastic and will break if a certain amount of pressure is applied.
EMC absorbs the pressure by deforming itself, so it returns to its original state without being crushed.
By adding EMC, new properties such as elasticity, cushioning and shock absorption can be added to base materials.

Excellent heat insulation

It is reported that EMC has a hollow structure, which has a low thermal conductivity and has the effect of efficiently reflecting the near-infrared area in sunlight.

With these double effects, heat shield and heat insulation properties are added simply by adding EMC to paint. Also, if you apply a thick coat of it to the interior wall material, you can expect the effect of preventing dew condensation.

Main applications of EMC

  • Weight reduction of thermosetting resins (Resins: epoxy, polyurethane, polyester, etc.)
  • Thermal barrier paint Reflective paint
  • Concrete Mortar
  • Construction putty Automotive repair putty
  • Light Weight Filler/Sealants For Construction / Automotive
  • Improved heat insulation（paint)
  • Lightweight clay
  • Surface modification (matting-effect Sealant)
  • Pore-forming material of Ceramics

Benefits of EMC (Construction Sealant)

EMC is used in construction sealant to create a variety of benefits.

1Cost reduction

It reduces polymer usage and contributes to cost reduction.

Polymer (Density 1.0 g/cm3)
@USD 5/kg　⇒　Cost/ℓ:5×1.0 =USD 5/ℓ

EMC-40(B) (Density 0.16g/cm3)
@USD 11/kg　⇒　Cost/ℓ:11×0.16 =USD 1.76/ℓ

When you replace 3wt% polymer with EMC, what happen?

Difference USD 0.52/ℓ!!10% Cost Saving !!

You can save the manufacturing cost USD 0.52 per liter and get lightweight, matte surface and other potions.

Cost reduction

2Good workability

Helping workability by improving extrudability. It does not drip easily, and cuts well, making it easier to work.

cautionCautions when using

  • Check if EMC is suitable to your product by tour inspection when it is delivered to you before using.
  • Scattering of EMC is considerably reduced compared with a plastic microsphere itself, but wear dust mask and goggles for safety when using EMC.
  • Calcium carbonate has possibility of separating a little from the plastic microsphere.
  • For further notes, please refer to the Safety Data Sheet.
