Advantages of Silicone o-ring cord :


Excellent Temperature Resistance : Silicone o-ring cord can withstand temperatures from -60°C to 230°C, making them ideal for extremely cold and hot environments.


Aging and Weather Resistance : Silicone material is resistant to UV rays, ozone and oxidation, making it ideal for outdoor applications and long-term exposure to a variety of harsh weather conditions.


Flexibility and Elasticity : Silicone material retains its flexibility and shape even after prolonged compression, ensuring reliable seals in dynamic applications.


Safe and Hygienic : Silicone material is chemically stable and non-toxic, meeting high hygiene standards, making it ideal for the medical, pharmaceutical and food industries.

Applications of Silicone o-ring cord


Silicone O-ring cord made from VMQ (silicone) are widely used across various industries due to their excellent resistance to vegetable oils, animal oils, fats, water (up to 100°C) and various organic and inorganic acids and alkali.


Aerospace industryIn the aerospace industry, silicone o-ring cord are used for seals that must withstand extreme temperatures and aging caused by ozone and harsh weather conditions. 

Medical industryThe medical industry uses silicone o-ring cord because of their chemical inertness and biocompatibility, which are crucial for medical devices. 

Food industryIn the food industry, silicone o-ring cord is also widely used due to its oil and grease resistance and good hygiene properties.


Despite the many advantages of silicone o-ring cord, they have poor resistance to silicone oils, aromatic mineral oils, fuels, and vapors above 120°C. Their operating temperature range is -60°C to +200°C, which can be extended to +230°C using special compounds.

Complete Pallet Preparation for rubber extrusions
Complete Pallet Preparation for rubber extrusions

Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
