Material Properties & Temperature Resistance

Each series of suction cups is designed and engineered for different applications. Below is a table to help you determine the ideal suction cup material:

Material  Temp. (Short time)  Temp. (Long time)  Wear resistance Oil resistance  Weather and ozone 
NBR -20°C to +110°C -10°C to +80°C Excellent Excellent Good
Silicone -40°C to +200°C -30°C to +180°C Unsuitable Unsuitable Excellent
Polyurethane +10°C to +50°C +10°C to +40°C Excellent Excellent Excellent
Natural Rubber -20°C to +80°C -10°C to +60°C Excellent Unsuitable Fair
Hightemp. Silicone  -70°C to +280°C -50°C to +230°C Excellent Excellent Excellent
Fluorine Rubber -10°C to +230°C -5°C to +200°C Excellent Good Good
EPDM -30°C to +150°C -20°C to +120°C Good Unsuitable Excellent

Shore hardness

When handling workpieces, the material of the vacuum pad is critical for durability, cycle time, and product integrity. The Shore hardness (Shore A for elastomers) determines how "soft" or "hard" the vacuum pad is.

 Shore-Hardness  Property When should it be used?
 30°-40° Very soft Irregular, uneven surfaces; delicate products 
 40°-55° Soft Standard applications; balanced ratio
 55°-70° Hard Smooth surfaces; fast cycles; heavy loads
