Thermo expandable microcapsulesテキサスホールデムポーカーphere

What is テキサスホールデムポーカーphere?

テキサスホールデムポーカーphere is a closed cell foaming agent that is sometimes referred to as thermo expandable microcapsules.
The hydrocarbon blowing agent resides inside an acrylic shell. When exposeテキサスホールデムポーカーo heat the shell softens while the pressure inside increases, allowing for rapid expansion.
Expansion starts gradually at the Tstart (activation) and reaches its peak expansion diameter at the Tmax (Maximum expansion temperature).
Once cooled, the microsphere maintains its shape encapsulating the blowing agent.
If the microsphere is heated past the recommendeテキサスホールデムポーカーmax or heated longer than recommended, the blowing agent will gradually escape the shell anテキサスホールデムポーカーhe microspheres will lose their shape.
KUREHA has lineup of microsphere grades suitable for a wide range thermoplastics; including advanced grades that are compatible with higher temperature polymers.
テキサスホールデムポーカーphere is used in wide range of applications including ceiling materials, glass run channels, weather strips, shoe soles, foam ink, wallpaper, heat release tape, artificial leather, and 3D printers.

When heated, the volume increases 50 to 170X depending on the grade used.
Expandable microspheres benefits include weight reduction, improved moldability, thermal anテキサスホールデムポーカーound absorption.
Microspheres are a precision foaming agent that are characterized by easy control of specific gravity, retention of closed cells, small sphere diameter and uniform distribution.
Microspheres provide the flexibility to be foamed in resin and within high permeability materials such as fibers and paints.

1) calculated by expansion ratio
2) after heat treatment (150℃, 5min)

テキサスホールデムポーカーphere grades are classified by "H" and "S" or "Unique" according to processing temperatures and expansion characteristics.
H series are suitable for expansion at 160℃-190℃
S series can be used in temperatures above 190 ℃, and are suitable for molding of engineering plastics and elastomers.
Unique series which have unique expansion characteristics.
