It is stable to acids, alkalis and salts at room temperature. Good abrasion resistance, flame-retardant, self-extinguishing, noise reduction and shock absorption, and good electrical insulation. Poor thermal stability. 70% light transmittance, suitable for less demanding display panels, not suitable for button panels, because the texture is particularly soft, the buttons are easy to be broken by long-term use, the life is not long, and they are not resistant to aging, The material can not be degraded, not environmentally, can not withstand high temperature, It can be use at room temperature within 65 degrees. Low water absorption, good dimensional stability, excellent bending, tensile and compressive strength, excellent heat resistance, cold resistance, electrical insulation and atmospheric aging resistance; Poor chemical resistance, poor fatigue resistance, prone to stress cracking. The general scope of application is the most extensive, except that it can meet the requirements of most membrane switch panels, Among them, the high light transmittance of glossy PC can meet the requirements of liquid crystal display windows PC matte, material, light transmittance 78%, material is softer than PET, can be bent at will, is not resistant to aging, can withstand weak acids and alkalis, and is also one of the most widely used materials on the market at this stage. (F150 is small matte), the emboseed feeling weaker than PET, the material is environmentally friendly and degradable, and it can meet export standards. Good chemical resistance, insoluble in common organic solvents, not resistant to alkali. It has excellent mechanical properties, electrical properties, rigidity, hardness and maximum toughness of thermoplastics, low water absorption, excellent wear resistance and friction resistance, and high dimensional stability. The tensile strength is comparable to aluminum film, which is much higher than PC and PVC. F150 is imported PET frosted material with high temperature resistance and aging resistance. Even if it is frosted, the light transmittance of the material is still very high. The light transmittance of PET is 89%, making the color more vivid. It is the most ideal substrate for making membrane switch circuits. It is suitable for products with high environmental requirements or products with digital tubes.
JRPanel Graphic Overlay thickness of the material

The thickness of the material :

The thickness of the plastic substrate is 0.25mm or below and is called a film. It is mainly used as the panel layer of the membrane switch. Various indicative patterns and text are printed on the back to indicate the operation area of the corresponding key switch. Depending on the size of the button, the material is thick, the touch force is increased, and the response is slow; the material is too thin, the feel is poor when touched, and the rebound is not obvious.

Thickness above 0.25mm is called plate, which is not suitable for 3D. It can be used as an indicative sign panel in the keyless operation area, and can also be used as a lining for membrane switches to increase its hardness.

Embossed Key Type:

JRPanel can provide various types of embossed-key as following picture.
The default is circle-embossed (the left 1st ). If you need other types, you can specify it in the remarks or drawings when placing an order.
JRPanel Graphic overlay Inspection & Check
Inspection & Check

Membrane switch & Graphic overlay

1. Check the color: The contrast of colors.
Due to ambient light and other reasons,
it can not be directly compared with the
real sample or computer pictures. It
needs to be checked with the Pantone
color card. The general colors can only
be closer, couldn't be same. JRPanel
uses Pantone Formula Guide Coated
card. [Finding color numbers on]

2. Shape inspection: Check the shape
and internal slots and windows accordingly
according to the product design

3. Appearance inspection: check the
graphics of the panel layer,the logo
text, etc, whether there are defects,
omissions, stains, etc. Whether the
window and press position are offset. If
there is protective film attached to the

4. Check the peel strength of the adhesive:
check whether the adhesive is the
adhesive selected according to the
order, and test the peel strength of the
adhesive is not less than 8N/25mm.
