CSM(Hypalon)

Description

Product name: Chlorosulfonated Polyethylene Rubber

Product abbreviation: CSM

Hypalon® is a registered trademark of DuPont Performance Elastomers.

Hypalon Rubber, previously a registered trademark of DuPont Elastomers, are a a group of peroxide and sulfur curable elastomers based on chlorosulfonated and chlorinated polyethylene. As a result of the manufacturing process, these polymers produce an elastomer with a completely saturated backbone as well as pendant groups suitable for varied vulcanization approaches. Due to its unique backbone configuration, Hypalon rubber vulcanizates are extremely resistant to attack by ozone, weather and oxygen.


Product function: The chemical structure bond of Chlorosulfonated Polyethylene is complete saturation. So vulcanization has excellent ozone resistance, atmospheric aging resistance, chemical resistance, ionizing radiation resistance and color stability function, good physical mechanical function, thermal aging resistance, low temperature resistance, flame resistance, abrasion resistance, electrical insulation function and etc.

Color and form: light yellow and irregularly-shaped chips

Molecular formula:{[(CH2)n1CHCl(CH2)n2]n3CHSO2Cl}n


Product Application

Auto parts


CSM is mainly used in air conditioning, hydraulic system, exhaust control, fuel pipeline, automobile steering power pipe, brake hose and rubber hose of vacuum regulating system. It can also be used as spark plug cap and ignition line, automobile sealing strip, driving wheel primer, etc.


Mixed compound


CSM can be modified with other rubbers. The processing properties of blends can be improved by blending CSM with fluorine rubber; the physical and mechanical properties and thermophysical properties of vulcanizates can be improved by blending CSM with ethylene propylene rubber; the blending of CSM with isoprene rubber in EVA polymer can produce a blend with skid resistance, wear resistance and oil resistance; and the vulcanization of CSM with PVC and PU in extruder can be improved by blending CSM with PVC and PU. Oil-resistant, ozone-resistant vulcanizates and so on, CSM can be blended with a variety of other rubber modification, not only to make up for the shortcomings of other rubber, but also its excellent performance incisively and vividly. This is reflected in tires, conveyor belts, shoes, cables, plywood, hoses and other high-demand rubber products.


Wire and cable


Chlorosulfonated polyethylene (CSPE) has excellent wear resistance and heat resistance, and is often used in the caterpillar materials of wires and cables. Secondly, because of its low water absorption, oil resistance, fire resistance, weather resistance, sunshine resistance, ozone resistance, corona resistance and other characteristics, CSPE has the characteristics of color and safety, and can make different color cable jackets to distinguish functions, even if it is not black. Products, but the UV resistance is also very good. Moreover, the cable of CSM sheath can meet the requirements of the standard of IEEE (International Association of Electronics and Electrical Engineers), and has been used in nuclear power plants.


Hose


When the hose industry has special needs, CSM hose will be preferred. Because of its excellent chemical resistance and low permeability to water and fluorinated refrigerants, it is often designated as a variety of air conditioning hose materials.


Waterproof rubber cloth


Chlorosulfonated polyethylene (CSPE) has the characteristics of natural vulcanization and anti-microbial growth, so it is often made into reinforced waterproofing adhesive for reservoir water storage, River embankment, roof waterproofing and so on. At the same time, because of its good chemical resistance, it is more widely designed in the chemical industry water treatment tank waterproof layer.


coating


The special properties of chlorosulfonated polyethylene (CSPE) and its anticorrosive coatings have been widely used because of their special properties. The characteristics of chlorosulfonated polyethylene anticorrosive coating are excellent shielding property, smooth surface, no chromogenic gene, strong adhesion, rapid drying at room temperature, thick film formation at one time, which can reduce construction times, less solvent volatilization, light environmental pollution, anti-ozone, ultraviolet radiation, excellent oxidation resistance and anti-nuclear radiation. Radiation performance, with very significant weather resistance and aging resistance; excellent acid, alkali, salt and chemical gas corrosion resistance; excellent flexibility and cold resistance, good water resistance, moisture resistance, mildew resistance, grease, solvent performance, and maintain bright color. Application fields of chlorosulfonated polyethylene anticorrosive coating: It can be widely used on the surface of light and heavy metals and cement structures indoors and outdoors, playing the role of anti-rust and anti-corrosion, and can be applied on railways, bridges, high-voltage transmission towers, containers, offshore drilling and oil production equipment, various vehicle chassis, heavy machinery, etc. Ship equipment and pipelines, gas cabinets, sewage tanks, nuclear power plant equipment, chemical equipment and pipelines and ground, storage tanks, ports and wharfs and other fields.


Architecture


CSM is used as sealant, PU foaming surface, insulating material, additives, foaming products and so on, and a large number of CSM waterproof rolls or waterproof and heat-insulating tapes are used, because CSM waterproof and heat-insulating tapes have excellent waterproof, heat-insulating and ultraviolet-resistant particularities. At the same time, in the process of roof construction, it still maintains heat. Plasticity can be bonded to each other by heating and bulk bonding, and no other synthetic rubber can have this excellent mixing.


All kinds of rubber color products


In order to maintain weatherability, especially ultraviolet resistance, the color of this product is almost black if it is manufactured with SBR, NBR or EPDM, but if it is manufactured with chlorosulfonated polyethylene, it can produce bright color products without affecting the excellent properties of sunscreen, weather resistance and ultraviolet resistance.


Rubber roller


Chlorosulfonated polyethylene cots have good properties of aging resistance, ozone resistance, chemical corrosion resistance and high temperature resistance, and have been widely used in special fields.


Waterproofing membrane


Chlorosulfonated polyethylene waterproofing membrane is an elastomeric waterproofing material made of chlorosulfonated polyethylene rubber as the main raw material and mixed with appropriate additives. Its main characteristics are as follows: 1. Because the molecular structure of chlorosulfonated polyethylene does not contain double bonds and has high saturation, the waterproofing material made of chlorosulfonated polyethylene as the main material is ozone-resistant. It is an incomparable new waterproof material for any rubber or plastic products with double bond structure. 2, high elongation and good elasticity. It can meet the needs of expansion or change or cracking and deformation of the base. Non combustible characteristics. The chlorine content of rubber itself is as high as 23%~45%. During the combustion process, when the flame leaves, the flame of waterproof membrane itself can extinguish itself, so it has good flame retardant performance. 3, high and low temperature performance is good. The coil can be used for a long time in the range of - 29 ~90 ~C, and can maintain good flexibility and corrosion resistance. The coil has excellent properties of acid, alkali, salt and other chemicals. 4. Good coloring properties. According to the user's requirements, different pigments can be selected to make waterproof rolls which are not easy to fade. The rolls can be laid by single-layer exposure method. The color is gorgeous and the rolls can be cold-constructed with little pollution and simple technology.

Chlorosulfonated polyethylene (CSPE) is not only suitable for the above fields, but also for Trailer tarpaulins, heat conveyor belts, raincoats, ship covers, aircraft roofs and jet structures such as military rubber boats. I will not enumerate all of them here. Of course, there are other unknown areas, which need to be explored and developed by you and me.
