        詳情
        There are too many places where seals are installed today. For example, seals are used on windows in the home where we live, on our cars, and on engineering equipment. So let's talk about the reason why the seal is used? Rubber seals have appeared in our daily life a long time ago, but there were too few places to use seals in that era. Not the same as now. Sometimes we will use rubber seals as waterproof seals in places we do n’t expect. This also reminds us that the development and progress of our country are moving forward day by day. So what are the benefits of installing a sealing strip?
        One: The sealing strip will make the windows we live in play a role of sealing and waterproofing, and a quiet life at home will bring a peaceful life to our family.
        Two: The sealing strip will give us the engineering equipment and environmental protection equipment to play the role of shock absorption, pressure resistance and oil resistance, and it will also have the effect of sealing and dustproof.
        Three: The sealing strip brings a quiet and comfortable environment in the car to our car, and prevents the sand and rain in the car from entering. In short, there are so many places where seals are used. We will not forget to produce perfect and qualified rubber seals for every manufacturer.
