Description:
Silicone sealing strip is a kind of silicone products, VMQ belongs to the extrusion processing, mainly plays
the role of sealing, so it can also be called as silicone sponge, foam silicone strip and so on.
Silica gel foaming sealing strip is a heat preservation pipe produced by a unique formula process. It has a high
temperature resistance of 250 degrees and a low temperature resistance of minus 50 degrees. It has a good sound
insulation and thermal resistance.It is mainly used for supporting electrical appliances, electronics, furniture equipment,
toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, cars, bottle sealing, building wall sealing
and other industries!
Silicone sealing strip is a kind of special comprehensive performance of good rubber, has excellent electrical insulation
performance, aging resistance, chemical stability, oxidation resistance, weather resistance, radiation resistance, physiological
inertia, good air permeability, high and low temperature resistance, can be used in -100℃ ~ 280℃ for a long time.Can be widely
used in aviation, electronics, petroleum, chemical industry, machinery, electrical appliances, medical, oven, food and other industrial
sectors of good electrical insulation sealing, liquid transport materials.High and low temperature resistance, oil resistance, non-toxic
and odorless, etc.The operating temperature range of silicone rubber is from -160℃ to 350℃.It has excellent heat resistance to oxygen
aging, ozone aging, light aging and weather aging properties.Good electrical insulation.
Silicone rubber is non-toxic, odorless and widely used in medicine.
