ANTISTATIC SILICONE RUBBERS FOR PAD PRINTING
The antistatic silicone elastomers developed by the CHT Group are composed of electrically conductive silicone polymers and specialty fillers. The RTV 2 silicone elastomers are designed to produce high quality printing pads.
The great variety of Shore hardnesses and the exact reproduction of the mould, produce a high-quality versatile printing process on common materials including:
- Porcelain
- All types of synthetic materials
- Electrical devices
The outstanding release properties of the silicones from organic and inorganic surfaces enable fine detailed reproduction by facilitating excellent transfer of the printing ink from the print pad. The silicone elastomers of the CHT Group have outstanding mechanical and chemical stability.
Electrostatic Charge
In pad printing, it is important that the image produced is sharp, clear, with defined outlines and solid colour fill is achieved. Static charges may affect the print quality in various ways. Electrostatic discharge could also damage sensitive electronic components within the part being printed.
The antistatic properties of our silicone elastomers help prevent the following undesired effects:
- Adhesion of dust and dirt on the pads
- Ink splashes and a blurred print appearance
- Static discharge shock during printing
Advantages of CHT silicone rubbers:
- Antistatic properties
- High transfer capacity
- Good tear strength
- Very good stability to chemicals
- Very good mechanical properties
- Excellent release properties
- Various Shore hardnesses
- Simple handling
