Silica gel sealing strip is widely used in various industries such as automobile, door and window, cabinet, refrigerator, container, etc. according to the requirements of different industries, we have developed unique automobile sealing strip, mechanical sealing strip, door and window sealing strip and other products.

Silica gel sealing strips can be classified into the following categories according to their uses:

(1) window glass sealing strip; (2) door sealing strip; (3) decorative strip and moulding strip;

(4) other sealing strips: trunk cover sealing strip, engine hood sealing strip, water tank sealing strip, emergency door sealing strip, etc.

Silica gel has the characteristics of non-toxic, environmental protection, high transparency, strong resilience, compression resistance, permanent deformation resistance, UV resistance, flame retardant, etc.

◆ heat resistance: silica gel has much better heat resistance than ordinary rubber. It can be used almost forever at 150 ° C without performance change; it can be used continuously for 10000 hours at 200 ° C; it can be used for a period of time at 350 ° C.

◆ cold resistance: ordinary rubber is - 20 ℃ ~ - 30 ℃, that is to say, silica gel still has good elasticity when it is - 60 ℃ ~ - 70 ℃, and some special silicone rubber can withstand extremely low temperature.

◆ hardness: the softness of imported silica gel is 40 ± 5 degrees, the softness of domestic silica gel is 50 ± 5 degrees, and the hardness is 80 ± 5 degrees.

◆ thickness: the minimum inner diameter of silicone tube is 0.5mm, the thinnest wall thickness is 0.5mm, and the maximum outer diameter is 500mm.
