EPDM elevator handrail rubber seal

Product Features: Based on the use of electrical cabinets and 20 years of experience in the research and development of sealing strips, Yitong Company has developed electrical cabinet sealing strips with its own characteristics - it has good sealing, waterproof, fireproof, insect-proof, windproof and light-proofing Anti-collision and long service life.
The electrical cabinet sealing strip is made of foamed and dense composite EPDM rubber with good elasticity, resistance to compression deformation, aging resistance, ozone chemical action, and a wide operating temperature range (℃~+℃). Containing unique metal clamps and tongue-shaped buckles, it is sturdy and durable and plays a key role in various electrical cabinets.

Mechanical sealing strips play a very good role in sealing, prevention, control, wear resistance, sound insulation, and shock resistance. They are widely used in mechanical dynamic seals and static seals such as electric power, petrochemical industry, light industry, instrument pipes, pumps, valves, etc., and are an alternative to rubber. Ideal new sealing material for traditional seals such as fluorine plastics.
Product analysis:
1: At present, sealing strips (br r) have been applied to various industries such as automobile doors, windows, cabinets, refrigerators, and containers. According to the requirements of different industries, unique automobile sealing strip machinery has been developed. Sealing strips, door and window sealing strips and other products, so they are widely used in sealing industries such as electronics, electrical lamps, lighting, pharmaceuticals, chemical machinery, equipment, textiles, chemical fibers, automobiles, etc.

EPDM rubber sealing strip material sealing strip:
Ethylene-propylene rubber (\) A copolymer of ethylene and propylene, generally divided into two-dimensional ethylene-propylene rubber and three-dimensional ethylene-propylene rubber. It is characterized by excellent ozone resistance, ultraviolet resistance, weather resistance and aging resistance, ranking first among general rubbers. Electrical insulation, chemical impact resistance, good elasticity, acid and alkali resistance, small specific gravity, and high filling and matching. The heat resistance can reach ℃, and it is resistant to polar solvents, ketones, esters, etc., but it is not resistant to aliphatic hydrocarbons and aromatic hydrocarbons. Its other physical and mechanical properties are slightly inferior to natural rubber and better than styrene-butadiene rubber. The disadvantage is that the self-adhesion and mutual adhesion are very poor and it is not easy to bond. Operating temperature range: approximately ℃ ~ + ℃. It is mainly used as lining for chemical equipment, wire and cable sheathing, steam hose, heat-resistant conveyor belt, automotive rubber products and other industrial products.
Two: Silicone sealing strips Silicone products:
Silicone material has good sealing performance, high temperature and weather resistance, anti-aging and impact resistance, shockproof and waterproof, and can fit all kinds of smooth surface materials

It can be self-adhesive with adhesive tape and has better sealing performance. The high-temperature resistant adhesive will not fall off after long-term use. Environmental protection, safety, good insulation, high temperature resistance, small compression deformation, strong resilience, non-toxic

Foamed silicone rubber foams evenly, and the density can reach /, Shore hardness. Environmentally friendly, non-toxic, odorless, good resilience, good flexibility, no bubbles or pores on the surface. High strength, long service life, product insulation and environmental protection, high and low temperature resistance, compression resistance, acid and alkali resistance, aging resistance, and UV resistance.

Smooth surface, uniform foaming density
Good surface non-stickiness and good air permeability.

Made of % high-quality silica gel raw materials and passed strict testing to comply with environmental standards.

High temperature resistance: high temperature

Heat resistance: silicone rubber has much better heat resistance than ordinary rubber and can be used almost forever at high temperatures without performance changes. It can be used continuously at low temperatures, and can be used for a period of time at low temperatures.

Weather resistance: Ordinary rubber degrades rapidly under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. And its physical properties only change slightly when exposed to ultraviolet rays and other climatic conditions for a long time. Anti-aging, corrosion-resistant, silicone itself is very inert.

Three: Butadiene rubber (BR) is a copolymer of butadiene and acrylonitrile. It is characterized by particularly good resistance to gasoline and aliphatic hydrocarbon oils, second only to polysulfide rubber acrylate and fluororubber, and better than other general-purpose rubbers. It has good heat resistance, air tightness, wear resistance and water resistance, and strong adhesion. The disadvantages are poor cold resistance and ozone resistance, low strength and elasticity, poor acid resistance, poor electrical insulation, and poor resistance to polar solvents. Operating temperature range: approximately ℃ ~ + ℃. Mainly used to manufacture various oil-resistant products, such as hose sealing products, etc.
Four: Natural rubber (R) is mainly composed of rubber hydrocarbons (polyisoprene) and contains a small amount of protein, moisture, resin acids, sugars, and inorganic salts. It has high elasticity, high tensile strength, excellent tear resistance and electrical insulation, good wear resistance and drought resistance, good processability, easy to bond with other materials, and is superior to most synthetic rubbers in terms of overall performance. The disadvantages are poor oxygen and ozone resistance, easy aging and deterioration, poor oil and solvent resistance, low acid and alkali corrosion resistance, and low heat resistance. Operating temperature range: approximately ℃ ~ + ℃. Make tires, rubber shoes, hoses, tapes, insulation layers and sheaths for wires and cables, and other general products. It is especially suitable for manufacturing torsional vibration eliminators, engine shock absorbers, machine supports, rubber metal suspension components, diaphragm molded products.
