The main characteristics of asbestos free gaskets are:
1.100% asbestos free, new environmentally friendly material, can be exported to major developed countries and regions such as Europe and America.
2. Good temperature resistance, pressure resistance, and compression resilience
3. Wide applicability, oil resistance, medium resistance, and airtightness.
4. Materials with higher mechanical strength are easy to cut and shape.
Definition of asbestos free gasket:
Non asbestos gaskets refer to synthetic fiber rubber gaskets that replace asbestos rubber gaskets. Some expand the meaning to include all asbestos free gaskets, such as polytetrafluoroethylene gaskets, rubber flat gaskets, expanded PTFE gaskets, flexible graphite composite gaskets, etc. The former is a narrow definition, while the latter is a broad definition. At present, the engineering community generally agrees with the broad definition, which refers to the narrow definition of asbestos free gaskets. The production of asbestos free materials in China is mixed, and there are not many manufacturers that can truly compare with foreign asbestos free materials. The quality difference is large, and the key for customers to choose is to use high-quality gaskets. Of course, there are many factors that affect sealing. In engineering projects, the reasonable selection of asbestos free gasket sealing materials requires comprehensive consideration and evaluation of the performance, usage conditions, service life requirements, and overall compatibility of various gaskets. A comprehensive analysis of the factors that may cause sealing failure in engineering is necessary to select asbestos free gasket materials of different categories and performance in order to save costs and achieve ideal sealing effects, and fully play the role of asbestos free gaskets.
Difference between asbestos free gaskets and non asbestos gaskets：
The term ASBESTOS FREE GASKET or NON ASBESTOS GASKET commonly used in European and American countries refers to gaskets that are 100% asbestos free. It can be translated into Chinese as "asbestos free gasket" or "non asbestos gasket", but currently in the domestic market, we generally refer to gaskets containing a certain amount of rock wool (5-20%) as non asbestos gaskets or non asbestos gaskets. Therefore, customers need to provide detailed instructions when ordering. In order to meet customers' demand for high-quality gaskets, we have sufficient inventory of some well-known foreign brands of asbestos free boards, such as Klinger, Garlock, Valqua, Gore, Frenzelit, etc.
Classification of asbestos free gaskets:
1. Non asbestos gaskets can be divided into two types based on the production process of the material: roller pressing plates produced by CAF (compressed asbestos rubber sheet production) method and copying plates produced by papermaking method, both of which belong to new environmentally friendly sealing products. Roller press plates are generally used for sealing pipeline flanges, and ZD-G1500 belongs to a type of roller press plate. The copying plate is mainly used for sealing components used in motor vehicles, such as engine gaskets, internal combustion engine cylinder gaskets, exhaust pipe gaskets, etc.
2. According to the classification of physical performance levels, it can be divided into three different levels: low pressure, medium pressure, and high pressure, as well as special asbestos free gaskets such as oil resistant, acid resistant, pressure resistant, high temperature resistant, refrigeration refrigerant plates, airtight plates, and marine sealing plates. Metal wires can also be added to reinforce the above materials, and graphite can be coated to increase temperature resistance. Graphite containing asbestos free graphite plates can also be customized with other performance asbestos free plates and various gaskets according to customers' special needs.
Specification of asbestos free gasket material:
Roller press board width x length (mm): 1500 × 4500 1500 × 4000 1270 * 3810, can be cut; Thickness (mm): 0.4-5.0
Copy board width of 1500; A multiple of 50000 in length; Thickness (mm): 0.3-1.2
Special specifications can be negotiated with customers
All products with a thickness of 0.8mm or more can be reinforced with steel wire mesh, coated with graphite, and treated with double-sided anti sticking.The color can be customized according to customer requirements.
