Classification of EPDM seal material knowledge
Views: 1018 Release date: 2018-09-05

EPDM rubber strips can be divided into two types according to the data of EPDM seals: dense rubber strips and foam rubber strips. The hardness of dense rubber strips is generally between 65 degrees and 90 degrees; the hardness of foam rubber strips is between 15 degrees and 35. The product is soft and has good resilience. It is suitable for various sealing blocks and gaskets.


EPDM EPDM sealing strip can be further divided into:

(1) Non-continuous vulcanization method (after cutting the extruded rubber strip to a certain length, it is vulcanized in a vulcanization tank, and the semi-finished product of the extruded rubber strip is vulcanized in a model);


(2) Continuous vulcanization (microwave continuous vulcanization, salt bath continuous vulcanization, hot air continuous vulcanization, etc.). A. Microwave continuous vulcanization composite sealing strip: Microwave vulcanization technology is a production technology that has been widely used since the energy crisis abroad in the 1970s.

Choosing microwave continuous vulcanization technology can not only produce co-extrusion of various materials such as metal core, compact rubber and styrofoam, but also has advantages over other continuous vulcanization equipment in terms of energy saving and running power. This technology is recognized by the world as a good process for producing extruded products. microwave

The characteristic of heating is that the heat directly occurs in the heated object, instead of being input from the outside as usual, so that not only the heat is generated quickly, but also the uniform distribution, which is conducive to the quality of the product traveling and greatly shortens the heating time. B. Salt bath vulcanization rubber strip: salt bath vulcanization

The salt bath system of nitrate has great environmental pollution and has been gradually selected. C. Hot air vulcanization rubber strip: hot air vulcanization has now developed into strong wind type vulcanization, even high temperature and high speed hot air vulcanization (Tmax: 450 ° C and Vmax: 60m / s) can reach flame pretreatment

Use, and security goes a long way.



Common sense of sealing tape

Selection of sealing tape for building doors and windows

The use of equipment for the construction of doors and windows requires sealing tape to close the closed seal between the profile and the glass, and between the fan and the frame. The sealing rubber strip plays a role of fixing glass in the application of doors and windows, buffering the vibration and blocking the flow of water and air. Door and window insulation function and airtightness function

It can have a serious impact on reducing energy consumption. The thermal loss of doors and windows with poor sealing is 5-6 times that of the wall. The energy saving power of doors, windows and curtain walls accounts for about 37-40% of the energy saving of the construction. Therefore, the rubber strip is a non-negligible functional accessory in the qualified energy saving of doors and windows. Its function and life expectancy should be

Attracted our attention.

At that time, due to various reasons, the plastic strip malls were mixed. There are also many developers and door and window companies that are using seals that do not meet the standards for "sealing tape for doors and windows" due to low prices. In addition to this problem, it is necessary for the manufacturers of rubber strips to make further progress to save energy.

The degree of importance of the door and window industry should also be used in the development, supervision, and production of windows and doors to identify the sealing strips. Pay attention to the following aspects when selecting sealing tapes to promote the wide progress of the quality of seals for doors and windows.

Data selection: The function and life of the sealant strip products depend primarily on the selection of data. From the perspective of the classification of China's chemical building materials, the primary information for door and window sealing tapes is divided into two categories: thermoplastic elastomer sealing tapes and vulcanized rubber sealing tapes.
