yellow silicone coating for timing belts

The core advantages of yellow silicone-coating timing belts include high-temperature resistance, food-grade safety, slip resistance, wear resistance, and anti-adhesion properties. The coating is typically yellow or semi-transparent yellow, commonly referred to as “food-grade yellow silicone timing belts.”

YONGHANG cover both timing belts and conveyor belts with silicone yellow coating. The silicone is applied without a joint to the toothed belt & conveyor belt up to a thickness of 15 mm. The advantages of a silicone coating are temperature resistance from -40°C to 220°C, anti-adhesion (adhesive and dirt-resistant), elasticity and excellent resistance to the ageing process. Due to the high coefficient of friction with steel, glass and paper, silicone is very suitable for the transport of these materials.

Belts for Vacuum Systems

To achieve optimal performance, packaging machines are equipped with a vacuum system that, when paired with timing belts machined to precise specifications, can significantly increase the machine’s cycle count.

To provide tailored solutions for all types of vacuum systems, we have invested in advanced technologies that enable us to design the ideal geometries for the slots and perform the necessary manufacturing on high-speed machining centers, ensuring rapid production times.

One of the industries where this solution is most commonly used is packaging, specifically in packaging machines where the film or wrapping reel is unwound onto a former tube using two coated timing belts. The wide variety of packaging types available on the market makes it challenging to select a single coating that maximizes machine performance. For this reason, we have analyzed various mixtures and hardness levels to best meet the specific needs of our customers.
