Sealing Tape Category

. EPDM rubber sealing tape

EPDM material, excellent overall performance, with outstanding ozone resistance, excellent weather resistance, very good resistance to high and low temperature performance, outstanding chemical resistance, resistance to a variety of polar solutes, relative density is small. The disadvantage is that it expands a lot in general mineral oil and lubricating oil, and it is generally a dark-colored product. Temperature range -60~+150℃. With its wide range of application and excellent comprehensive performance, it is recognized by domestic and foreign industry enterprises.

.  Silicone rubber sealing tape

It has outstanding high and low temperature resistance, ozone resistance and weather resistance; excellent hydrophobicity and proper air permeability; unparalleled insulating properties; it can reach the hygienic level of food hygiene requirements, and can meet the requirements of various colors. The disadvantage is that the mechanical strength is the worst among the rubber materials and it is not oil resistant. Use temperature range -100~+300℃. It can be applied to high temperature, cold, ultraviolet irradiation strong area as well as middle and high rise buildings.

.  Neoprene Sealant(CR)

Compared with other special rubber, the individual performance is poorer, but the total performance balance is good. Excellent weather resistance, ozone resistance, heat aging resistance and oil solvent resistance, good chemical resistance and excellent flame resistance, good adhesion. Poor storage stability, hardening occurs during storage, bad cold resistance. Relative density is large. Generally black products. Used in the environment of oil resistance, heat resistance, acid and alkali resistance requirements. Temperature range -30~+120℃.

.  Nitrile Rubber Seal

The main features are oil resistance, solvent resistance, but not resistant to ketone, ester and chlorinated hydrocarbons and other media, elasticity and mechanical properties are very good. The disadvantages are easy to aging and cracking in ozone and oxidation, poor cold resistance and low temperature resistance.

.  Thermoplastic elastomer sealing tape

With good elasticity and excellent abrasion resistance, good oil resistance, hardness can be adjusted in a wide range (Shore A hardness of 65 ~ 80 degrees), mechanical properties (tensile strength, elongation) is superior, excellent cold resistance and resistance to chemicals intertwined with corrosion resistance, the price of raw materials is higher. For recyclable materials. Temperature range -60~+80℃. Suitable for use in earthquake-prone areas, areas subject to strong vibration such as near railroads or plants with powerful cranes, and areas subject to strong ultraviolet radiation.

.  Thermoplastic Vulcanized Rubber (TPV) Sealing Tape

With the flexibility and elasticity of rubber, TPV seals can be produced by plastic processing methods without the need for vulcanization, and the waste material can be recycled and reused. Is a wider range of performance materials, heat resistance, cold resistance, good, small relative density, oil resistance, solvent resistance and chloroprene rubber performance is similar to the compression permanent deformation and abrasion resistance and other not so good. Temperature range -40~+150℃. Can be applied to cold, as well as medium and high-rise buildings.

.  Plasticized polyvinyl chloride (PPVC) sealing tape

Material is cheap and easy to get, with corrosion resistance, wear resistance, acid and alkali and all kinds of chemical media, combustion resistance, high mechanical strength; the disadvantage is that with the migration of plasticizers within the system, with the prolongation of time to become hard and brittle, loss of elasticity, not aging resistance, weather resistance and low temperature performance is poor. Generally dark-colored products. Suitable for light is not strong, the temperature change is not big, the climate conditions are not bad occasions.

.  Surface coating material

The surface of the sealing strip is coated with polyurethane, silicone, PTFE and other substances to replace the traditional process of surface flocking. The coated sealing strip has good abrasion resistance and smoothness, especially the sealing strip coated with silicone surface coating, the surface friction coefficient is small, which is conducive to the sliding of doors and windows. It is suitable for use on doors and windows with sliding doors and window fans. It is a substitute for traditional siliconized wool strips.
