What Are You Looking For?
There are many categories of rubber strips, as follows:
1. Silicone rubber sealing strip
It has outstanding high and low temperature resistance, ozone resistance and weather resistance; it has excellent hydrophobicity and appropriate breathability; it has unparalleled insulation properties; it can meet the hygiene level required by food hygiene and can meet the requirements of various colors. The disadvantage is that the mechanical strength is the worst among rubber materials and it is not resistant to oil. Operating temperature range -100～300℃. It can be used in areas with high temperature, cold, strong ultraviolet radiation and medium and high-rise buildings.
2. Neoprene sealing strip (CR)
Compared with other special rubbers, individual properties are worse, but the overall performance balance is good. It has excellent weather resistance, ozone resistance, heat aging resistance, oil resistance and solvent resistance, good chemical resistance, excellent flame resistance, and good adhesion. The storage stability is poor, hardening will occur during storage, and the cold resistance is not good. The relative density is large. Generally black products. Used in environments that require oil resistance, heat resistance, acid and alkali resistance. Operating temperature range -30～120℃.
3. Nitrile rubber sealing strip
The main feature is that it is resistant to oil and solvents, but is not resistant to media such as ketones, esters and chlorinated hydrocarbons. It has good elasticity and mechanical properties. The disadvantage is that it is prone to aging and cracking in ozone and oxidation, and has poor cold resistance and low temperature resistance.
4. Thermoplastic elastomer sealing strip
It has good elasticity and excellent wear resistance, good oil resistance, wide adjustable hardness range (Shore A hardness 65~80 degrees), superior mechanical properties (tensile strength, elongation at break), excellent The cold resistance and chemical corrosion resistance are intertwined, and the price of raw materials is relatively high. For recyclable materials. The operating temperature range is -60～80℃. It is suitable for areas with strong vibrations such as earthquake-prone areas, near railways or factories with high-power cranes, as well as areas with strong ultraviolet radiation.
5. Thermoplastic vulcanizate (TPV) sealing strip
It has the flexibility and elasticity of rubber and can be produced using plastic processing methods without vulcanization. The waste materials can be recycled and reused. It is a material with a wide performance range, good heat resistance and cold resistance, low relative density, oil resistance and solvent resistance similar to chloroprene rubber, but not very good in resistance to compression permanent deformation and abrasion. The operating temperature range is -40～150℃. Suitable for cold and medium- and high-rise buildings.
