Standard Specifications & Characteristics of Main Grades of ST-gel

We offer products of various impedance and high adhesiveness to products that are almost completely nonadhesive.

Grade Sub-grade Applications (Examples) Thickness (For the Gel Alone) Roll Length (Standard Value) Characteristics
SR SR-H Low Frequency Stimulation 0.8mm 100m Highly Adhesive
SR-R 0.75mm 100m Maintains adhesiveness even after repeated uses
NR NR Return Electrodes 0.5mm 100m Low corrosiveness in contact with AL sheet
CR CR-S ECG 0.6mm 100m Low impedance and soft adhesiveness
CR-H 0.6mm 100m Low impedance and gel does not stick out far
HIT HIT R-ECG 0.65mm 100m Very tacky immediately after being applied to the skin.
AG AG-01 Bioadhesive Materials 0.1mm 150m High adhesiveness suitable for long-hour application when paired with base film
G G-CR Other 0.3, 0.5, 1.0mm 100m, 150m Low impedance, low adhesiveness and elastic
G-SC 0.3, 0.5, 1.0mm 100m, 150m Low adhesiveness and elastic
  • Standard Roll Width: 300mm
  • Protective Film Composition: 60μmPE/100 or 125μmPET or 100μm release paper (3 or 6 inch paper core)

Rolls
Can be supplied in rolls.
T Type (Nylon Cloth) T Type (Nylon Cloth)
SheetsRolls
T Type (Nylon Cloth)
A flexible, highly transparent mesh made of fine nylon cloth.
Suited for applications requiring flexibility.
S Type (Polyester Nonwoven Fabric) S Type (Polyester Nonwoven Fabric)
Sheets
S Type (Polyester Nonwoven Fabric)
A fairly rigid material with low flexibility.
Suited for punching, cutting and situations where the gel is handled on its own.
Can only be supplied in sheets.
M Type (Polyester Nonwoven Fabric) M Type (Polyester Nonwoven Fabric)
SheetsRolls
M Type (Polyester Nonwoven Fabric)
A more flexible nonwoven fabric than the S Type.
Suited for continuous cutting.

*Please consult with us on for other types with or without intermediate backing materials.
