These solutions differentiate themselves not only by their non-marking capabilities, but also by their abrasion resistance and exceptional mechanical performance at temperatures that are as high as 160°C.
Developed for the cosmetic industry, SITON has resistance to high temperatures and abrasion

SITON was originally developed to satisfy the specific requirements of the cosmetics industry, which required non-marking suction cups to handle delicate products such as lipsticks. After SITON had been developed and tested, COVAL observed its resistance to high temperatures, up to 160°C at peak, and exceptional abrasion resistance.
A greater durability for the material, prolunging the life of suction cups
This rare combination of properties is highly sought-after in the plastics industry, where SITON’s thermal resistance makes it easy to handle hot parts as they are removed from the mould without altering them or leaving marks. Compared with traditional materials, SITON offers greater durability, prolonging the life of suction cups. This reduces the need for frequent replacements and minimizes machine downtime.
Sizes from 2 to 200 mm, it is the extensive range of SITON suction pads

COVAL offers an extensive range of SITON suction pads, now covering 80% of the range of standard suction pads in sizes from 2 to 200 mm. Whether flat, oblong or bellows suction cups, SITON has become the standard at COVAL, and has become a reference standard in the plastics industry, especially for plastic parts coming out of the mould.
The applications for SITON:
- Plastics: handling of products which are still hot while being removed from the mould.
- Cosmetics: handling of fragile products such as lipsticks.
SITON, the qualities that make the difference:
- Non-marking: bright colour and silicone-free;
- Good mechanical performance at high temperatures, 130°C continuous and up to 160°C peak;
- Excellent abrasion resistance.
