Rubber sealing strip is a sealing element made of rubber, mainly used to prevent external dust, air, water, etc. from entering the system. It is widely used in the fields of automobiles, machinery, doors and windows, and plays a role in dust prevention, insect prevention, waterproofing, fixation, sound insulation, shock absorption, and sealing.
Characteristics of rubber sealing strips
|
1. Non toxic and environmentally friendly: The rubber sealing strip is made of environmentally friendly materials, non-toxic and harmless, and meets environmental requirements.
2. Anti aging performance: the rubber sealing strip has excellent anti-aging performance, which can maintain its high sealing performance in the temperature range of -50 ºC to 120 ºC, and will not crack or deform after long-term use.
|
3. High and low temperature resistance: Rubber sealing strips can maintain good sealing performance at extremely low temperatures (-50 degrees) and extremely high temperatures (120 degrees), suitable for various harsh environments.
4. Chemical resistance: It has good chemical resistance and can maintain stability in various chemical environments.
5. Good elasticity: Rubber sealing strips have good elasticity and resistance to compression deformation, which can adapt to various shapes and materials of products and meet different design requirements.
6. Wide applicability: Rubber sealing strips are widely used in various fields such as automobiles, doors and windows, machinery, electronics, and electrical cabinets, and are suitable for various occasions that require sealing.
