Material Grades

ST-gel is a hydrogel born from the unique polymerization technologies of Sekisui Plastics. This is a safe and high performance material which consists of water, and where necessary humectant and electrolytes stabilized in a hydrophilic resin matrix.

CR (For ECG electrodes)

CR Grade
CR Grade

A hydrogel suited for ECG, EMG (electroencephalograph electrode) electrode etc. sensor applications.
Low impedance and provides superior non-polarity and defibrillation tolerance through combination with Ag/AgCl (silver/silver chloride) elements.
Good adhesion to skin surface allows for stable measurements.

SR (For TENS/EMS electrodes)

SR Grade
SR Grade

A hydrogel suited for electrical stimulation applications such as TENS and EMS electrodes.
Weight only changes slightly when dried and is suited for repeated applications.

NR (Return electrode)

NR Grade
NR Grade

A hydrogel which is designed so as to minimize causing corrosion when directly applied to metal.
Suitable for neutral electrodes. Has the same characteristics as the SR grade.

HIT (Resting ECG electrodes)

HIT Grade
HIT Grade

A hydrogel suited for Resting ECG electrodes and other types of disposable electrode applications.
Shows a strong adhesiveness immediately after being applied to the skin.

AG (High adhesiveness)

AG Grade
AG Grade

A hydrogel with strong adhesiveness comparable to that of commercially available adhesive tape.
Excellent continuous adhesiveness suited for biomedical adhesive applications.

G (High elasticity)

A rubber-like hydrogel with high elasticity and tensile strength.
A hydrogel with superior light permeability.

G GradeG Grade
G Grade

CP (Cosmetic packs)

CP Grade
CP Grade

A hydrogel suitable for pack materials in cosmetic and quasi-drug products.
Allows for combinations of a variety of active ingredients, possesses a watery external appearance and excellent adhesiveness and provides a continuous cooling sensation.
