Silicone rubber ring, water cup cover, heat-resistant silicone sealing ring, leak proof O-ring, silicone rubber ring, waterproof ring, sealing ring

This silicone sealing ring is designed specifically for water cup lids and is made of food grade silicone material. It belongs to the O-ring type sealing ring (referred to as O-ring). It has excellent high temperature resistance, leak prevention, and waterproof performance, and is widely used in daily necessities such as insulated cups, freshness boxes, and rice cookers, ensuring liquid sealing and food safety. The core features are as follows:

Excellent high temperature resistance:

It can work stably for a long time in the temperature range of -60 ° C to+200 ° C. Special formula versions (such as high-temperature resistant silicone materials) can withstand high temperatures of 250 ° C or even 400 ° C. This makes it suitable for high-temperature environments such as hot water bottles and ovens, and it is not easy to deform or release harmful substances at high temperatures.

Leak proof and waterproof design:

As an O-ring structure, it can tightly fit the gap of the water cup lid, effectively preventing liquid leakage and air from entering, keeping the contents fresh (such as coffee, tea). The elasticity and flexibility of silicone make it suitable for different shapes of lid openings, even after frequent opening and closing, it can restore its original state and avoid water leakage problems.

Safety and environmental advantages:

Food level certification: It meets international standards such as FDA and ROSH, is non-toxic and tasteless, can directly contact food, and ensures safe use - strong durability: anti-aging, tensile resistance and chemical corrosion resistance (such as acid and alkali), long service life, and is not easy to yellowing or damage. In addition, the materials are environmentally friendly and pass relevant tests, and are suitable for household and children's products scenarios (such as children's cups). The application scenarios are wide:

Mainly aimed at sealing water cup lids, but also compatible with household appliances such as freshness boxes, rice cookers, water dispensers, etc. It is simple and does not require additional tools. Simply insert it into the lid slot to achieve plug and play.
