Standard rubber sealing strip 

Vulcanization method can be divided into a continuous vulcanization method and continuous vulcanization method in two categories. Non continuous vulcanization: strip of the production in accordance with the certain length truncation, put a truncated respectively in the vulcanization vulcanizing tank, after forming the strip to be included in the corresponding mold vulcanization, to produce the final finished product; In the continuous vulcanization, rubber sealing strip standard production is made of softness to have, not too stiff, flat surface to smooth sleek, cannot appear word word abut. Continuous vulcanization, and the basic requirement of the continuous vulcanization production is the same, the only difference is in the process of production is not cut into section by section, is continuous, making fixed number of meters, the fixed number of meters are usually hundreds of meters; In continuous vulcanization, rubber sealing strip standard in addition to the flexibility to have, not too stiff, flat surface to smooth sleek, cannot appear word word abut place outside, also can't appear the trace of fracture. 

The characteristics of the rubber sealing strip 

1, product non-toxic, environmental protection, superior anti-aging, high and low temperature resistance and chemical medicine drug resistance performance, has good elasticity and compression deformation resistance, use for a long time not to crack or deformation, in - between 50 and 120 degrees can maintain its original high sealing performance, has been cars, Windows and doors, machinery, electronics, electrical cabinets and so on manufacturing a wide range of applications. 

2, to the different shapes, different materials, or cold resistant, heat resistant, foaming and has special performance requirements of products, all can meet the needs of the design and use. 

The rubber sealing strip maintenance of common sense 

1, vulcanized rubber sealing strip 

As a general rule, be epdm material. Comprehensive performance is excellent, with outstanding resistance to ozone, excellent weather resistance, good resistance to high temperature and low temperature performance, outstanding resistance to chemicals, can a variety of polar solute, relative density is small. The disadvantage is that large amount of expansion in the general mineral oil and lubricating oil, are generally dark products. Use temperature range - 60 ~ 150 ℃. With its applicability is wide and comprehensive performance is excellent, received the recognition from the industry enterprises at home and abroad. 

2, silicon rubber sealing strip 

With outstanding resistance to high and low temperature properties, resistance to ozone and weather resistance. Has excellent hydrophobic and appropriate permeability; Has the incomparable insulation performance; Can meet the food hygiene requirements of health level, can satisfy the requirement of all sorts of color. Faults is worst in mechanical strength in the rubber, oil resistant. Using temperature range 100 ~ 100 ℃. Can be applied to high temperature, strong cold, ultraviolet radiation area and the high-level architecture. 

3, neoprene sealing strip (CR) 

Compared with other special rubber, individual performance is poor, but the total balance of good performance. Have excellent weather resistance, ozone resistance, thermal aging and oil resistance, solvent resistance, good chemical resistance and excellent flame resistance, good adhesive properties. Storage stability is poor, hard phenomenon will occur in the process of storage, cold resistance is not good. Relative density is bigger. As a general rule, be black products. Used in oil resistant, heat resistant, resistant to acid and alkali environment. Use temperature range - 30 ~ 120 ℃. 

4, nitrile rubber sealing strip 

Main characteristic is oil resistant, solvent resistance, but not resistant to ketones, esters and chlorinated hydrocarbon medium, the elastic and mechanical performance is very good. Defect is the ozone oxidation and easy aging crack, cold resistance, low temperature resistance is poor. 

5, thermoplastic elastomer sealing strip 

Has good flexibility and excellent abrasion resistance, good oil resistance, wide range of hardness can be adjusted (shaw A hardness 65 ~ 65 degrees), superior mechanical properties (tensile strength, tensile elongation), excellent cold resistance and resistance to chemical corrosion performance, the higher the price of raw materials. As can be recycled material. Use temperature range - 60 ~ 80 ℃. Suitable for near earthquakes, railway or with the area of intense shaking, such as the workshop of high-power crane and ultraviolet irradiation strongly region. 

6, thermoplastic vulcanizates (TPV) sealing strip 

With rubber flexible and elastic and plastic processing methods for production are available, and no sulfide, waste recycling, and used again. Wide is the performance of materials, good heat resistance, cold resistance, relative density is small, oil resistance, solvent resistance and neoprene, compression permanent deformation resistance and good wear resistance, etc. Not so good. Use - 40 ~ 150 ℃ temperature range. Can be applied to cold, and the high-level architecture. 

7, plasticized PVC sealing strip (PPVC) 

Material was cheap, corrosion resistance, abrasion resistance, resistance to acid and alkali, and all kinds of chemical medium, combustion resistance, high mechanical strength. Defect is coordinate system plasticizer migration, over time become hard brittle, lose elasticity, ageing resistance, weather resistance and low temperature performance is poor. As a general rule, be dark products. Apply Yu Guangzhao is not strong, the temperature change is not big, climate condition is not bad. 

8, surface coating material 

Is in the surface of the sealing strip coating materials such as polyurethane, silicone, ptfe, to replace the traditional process on the surface of flocking. The sealing strip after coating has good wear resistance, smoothness, especially the coated silica gel sealing strip after the surface coatings, surface friction coefficient, is advantageous to the sliding door to door. Suitable for with sliding door, casement Windows and doors. Is a traditional range of alternatives.
