Manufacturer of Food Grad Lunch Box Silicone Sealing Rings Rubber Ring - Silicone EPDM Foam Sponge Rubber Seal Strip Profile – Chaojie

Product Description

This highly versatile material offers all off the benefits of silicone rubber, but enables better sealing with lower compression forces due to the cellular structure.This sponge strip is an extremely resilient silicone, it displays excellent resistance to heat, weathering, ozone and a wide range of chemicals. It is impervious to UV lighting, non-toxic, chemically inert, retains its properties over a wide temperature range from -60 ~250°C. 

Sponge silicone gaskets have a cellular structure that offers cushioning and padding. There are two basic types of sponge silicones: open-cell and closed-cell. Open-cell silicones contain interconnected pockets that allow water, air, and chemicals to pass unless the gasket is compressed. Closed-cell silicones have pockets that are filled with nitrogen to prevent these substances from passing at low pressures.
