Application of Recycled Rubber in Sponge Foam Sealing Strip

Application of Recycled Rubber in Sponge Foam Sealing Strip Sponge foam sealing strip has low density, good elasticity, good sealing effect and good cushioning performance. It is usually made of continuous extrusion vulcanization of foam rubber and is used for sealing in various occasions. The common raw materials for sponge foam sealing strips are EPDM, nitrile rubber, neoprene and butyl rubber, but the price of raw rubber on the market has been very high, which is a big test for manufacturers; the price of rubber recovered from waste rubber products is much lower than that of raw rubber. Can it be used to produce sponge seals to reduce raw material costs?

What are the functions and characteristics of sponge foam sealing strip?

What are the functions and characteristics of sponge foam sealing strip? Sponge foam sealing strips are usually divided into two types: EPDM rubber foam sealing strips and silicone rubber low temperature resistant foam rubber sealing strips. The price difference between the two types of foam seals is also large. There are some differences between these two types of foam seals, which are better than EPDM foam seals in terms of black color, low temperature resistance and 120°C aging resistance. The advantages of tear resistance and corrosion resistance Many customers choose this rubber foam sealing strip, especially the price is relatively suitable. The other is sponge foam sealing strip, which has the advantage of strong low temperature resistance and can reach a low temperature of 280 degrees.

Manufacturing method of sponge foam sealing strip

Although the investment of sponge foam sealing strip is small, its role can not be ignored. Therefore, there is no need to choose those counterfeit products in order to reduce costs. Next, let's introduce the use of sponge foam sealing strip and the purchase skills of window seal. The identification method is very simple. 1. If there is a peculiar smell, smell it with your nose. Ordinary PVC material will have a little mellow, almost too little smell. 2. Wrap the sponge foam sealing strip around the profile as tightly as possible and place it at high temperature for a period of time. Observe whether there is any stain or discoloration on the contact surface between the profile surface and the sealing strip, and whether there is dust on the surface of the sponge foaming sealing strip.

How about the performance of sponge foam sealing strip

What is a sponge foam sealing strip? Sponge foam sealing strip is a kind of sealing strip that uses the characteristics of certain materials to produce pores in it through processing. How is its performance? In response to this problem, Dongsheng will give you a brief explanation. The sponge foam sealing strip is formed by microwave vulcanization process at one time, and the surface is light and beautiful, and there is no contact trace. It has good elasticity, compression deformation resistance and good aging resistance. Good flame retardancy, low smoke, low toxicity; product performance is stable, high dimensional accuracy. Sponge foam sealing strip has low heat insulation and thermal conductivity, and has good heat insulation; light weight, strong toughness, light weight, strong

What is the function of sponge foam sealing strip

With the development of traffic, buildings and modern facilities, noise pollution is becoming more and more serious. Long-term overload noise can cause damage to the central nervous system. Accordingly, the demand for acoustic foam sealing strips is also increasing. What is the function of sponge foam sealing strip? 1, the so-called sponge foam sealing strip, of course, is sound insulation. Sponge foam sealing strip can effectively inhibit the transmission of dynamic and static, so as to play the role of sound insulation. 2. The second is to reduce heat conduction. The thermal conductivity of the sponge foam sealing strip is much lower than that of the general sealing strip, which effectively reduces the heat conduction through the door and window gap.

Function and characteristics of sponge foam sealing strip

Sponge foam sealing strip is usually divided into two kinds, EPDM rubber hollow sealing strip and silicone rubber low temperature resistant hollow rubber sealing strip. The price difference between the two types of hollow object sealing strip is also very large. There are some differences between these two types of hollow sealing strips, which are better than EPDM hollow sealing strips in black, low temperature resistance and 120 ℃ aging resistance. The advantages of tear resistance and corrosion resistance Many customers choose this rubber hollow sealing strip, especially the price is relatively appropriate. Another kind of sponge foam sealing strip is sponge hollow sealing strip, which has the advantage of strong low temperature resistance and can reach the low temperature requirement of 280 degrees.
