The suction cup material HT1 is a special compound developed by Schmalz that is specially tailored to the requirements of glass handling. The material HT1 was designed to handle sensitive surfaces such as glass or displays safely and with minimized marks, while ensuring maximum process reliability. Thanks to its high temperature resistance, the material HT1 is also ideal for demanding applications in the automotive glass sector.
The material HT1 is mainly used in the glass sector. In the automotive industry, suction cups made of the material HT1 enable the safe handling of front and side windows – even at high temperatures of up to 170 °C, as occur directly after the bending furnace. For flat and float glass, the suction cups ensure precise positioning without displacement. For displays and touchscreens, the material protects surfaces from unwanted marks while handling and ensures the highest quality. The suction cups made of the material HT1 also contribute to efficient integration into production lines for window glass and thus supports seamless processes in glass production.
The material HT1 has properties that make it particularly suitable for various industrial applications.
Its high temperature and ozone resistance ensures a long service life even under demanding conditions. The good abrasion resistance reduces the resulting abrasion, keeping processes cleaner and reducing the risk of contamination. At the same time, the material HT1enables handling with leaving minimized marks, reliably protecting sensitive surfaces.
Sensitive Electronics Perfectly Handled – Minimized Marks, Maximized ESD Protection
In electronics manufacturing, there is no second chance. One tiny mark, one static discharge and entire batches are ruined. Not with us!
Our innovative suction cups made the material of HT1-ESD solve these challenges and many more: They protect workpieces from unwanted marks and ESD damage. With our suction cups, you benefit from:
Thanks to our extensive expertise in material development, the suction cup material HT1-ESD stands for cutting-edge technology and sets new standards in electronics manufacturing.

The material HT1 is available in various suction cup series from Schmalz. In combination with the matching spring plungers, the suction cups enable particularly gentle handling, as height differences can be compensated and workpieces can be gripped safely. This ensures seamless integration into automated handling systems and increases efficiency in production.
HT1 is a suction cup material developed by Schmalz. It is a proprietary special compound that has been designed for the requirements of the glass industry.
The material HT1 is primarily used in the glass sector, for example in the handling of automotive glass or displays. It serves as the material for various suction cups from Schmalz that are specially designed for these demanding applications.
Suction cups made of the material HT1 enable handling of sensitive surfaces leaving as few marks as possible and are highly temperature and ozone resistant, which gives them a correspondingly long length of service life. The good abrasion resistance also helps to ensure clean processes.
The material HT1 is used in various suction cup series from Schmalz.
Yes, Schmalz also offers the material HT1-ESD. This variant has been specially developed for electronics production and also protects sensitive components from electrostatic discharge (ESD).
