Product Description
CPE resin, also known as chlorinated polyethylene resin, is a thermoplastic elastomer made by chlorinating polyethylene. It has excellent weather resistance, chemical resistance and flame retardancy, making it a popular material for a wide range of applications such as wire and cable insulation, automotive parts and roofing membranes. CPE resin is also known for its good impact strength and flexibility, which makes it an ideal material for products that require durability and toughness.
CPE is divided into two series depending on the final application, the IM-HT series is designed for plastic impact modification, and the CM series is designed for rubber applications. In thermoplastics, the IM-HT series is used as an impact modifier for PVC-based window profiles, pipes and other interior profiles. When used in thermoset materials, the CM series provides a good balance of oil resistance, chemical resistance and heat resistance as well as good flame retardancy in automotive, wire and cable and general rubber applications.
Plastic product modification: CPE, as an impact modifier for polyvinyl chloride (PVC) plastics, can improve the toughness of PVC products and is suitable for manufacturing pipes, plates, wire insulation layers, profiles, films and shrink films, etc.
In addition, CPE is also suitable for the modification of plastics such as polyethylene (PE) and polypropylene (PP) to enhance their flame retardant and printing properties
Rubber products: In the rubber industry, CPE is used to manufacture high-performance, high-quality special rubber products such as wires and cables, highly flame-retardant conveyor belts, etc. Its heat resistance, flame retardancy and aging resistance make it an ideal choice for these fields
Wires and cables: CPE's flame retardancy and aging resistance make it widely used in the manufacture of coal mine cables, wires that meet UL and VDE standards, and other products
Pipes and tapes: CPE is used to manufacture hydraulic hoses, automotive hoses and various tapes. These products have important applications in machinery, automobile manufacturing, construction and other fields
Waterproof materials: The blend of CPE and PVC performs well in the field of waterproof materials, and the waterproof rolls made of it are mid-range
Features
1. CPE is a saturated rubber with excellent resistance to heat and oxygen aging, ozone aging, acid and alkali, and chemicals.
2. CPE has average oil resistance, among which the resistance to ASTM No. 1 oil and ASTM No. 2 oil is excellent, which is equivalent to NBR; the resistance to ASTM No. 3 oil is excellent, better than CR, and equivalent to CSM.
3. CPE contains chlorine, has excellent flame retardant properties, and has burning and dripping properties. It can be matched with antimony flame retardants, chlorinated paraffin, and Al(OH)3 in appropriate proportions to obtain flame retardant materials with excellent flame retardant properties and low cost.
4. CPE is non-toxic, does not contain heavy metals and PAHs, and fully meets environmental protection requirements.
5. CPE has high filling performance and can be made into products that meet various performance requirements. CPE has good processing performance, and a variety of grades are available with Mooney viscosity between 50-100.
Uses
In the late 1990s, the domestic demand for high-performance flame-retardant rubber was increasing, especially the development of the wire and cable industry and the automotive parts manufacturing industry, which led to the consumer demand for rubber-type CPE. Rubber-type CPE is a special synthetic rubber with excellent comprehensive performance, heat resistance and flame retardancy.
Chlorinated polyethylene resin is a new type of synthetic material with a series of excellent properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame-retardant conveyor belts, waterproof rolls, films and various special-shaped products. CPE can also be blended with polypropylene, high and low pressure polyethylene, ABS, etc. to improve the flame retardant properties, aging resistance and printing properties of these plastics. CPE can be regarded as a random copolymer of ethylene, polyethylene and 1,2-dichloroethylene. Its molecular chain is saturated and the polar chlorine atoms are randomly distributed. Because of its excellent physical and chemical properties, it is widely used in machinery, electricity, chemicals, building materials and mining industries. CPE is better than most rubbers in heat resistance, ozone resistance, weather resistance and aging resistance, better than nitrile rubber (NBR) and chloroprene rubber (CR) in oil resistance, and better than chlorosulfonated polyethylene (CSM) in aging resistance; it is resistant to acid, alkali, salt and other corrosive properties, non-toxic, flame retardant and explosion-proof.
Mainly used in: wires and cables (cables for coal mines, wires specified in standards such as UL and VDE), hydraulic hoses, automotive hoses, tapes, rubber sheets, PVC profile pipe modification, magnetic materials, ABS modification, etc
.
Storage and transportation conditions
Keep the storage container sealed, put it in a tight storage container, and store it in a cool and dry place.
Application coordination
Reinforcement and filling system
CPE is a non-self-reinforcing rubber that requires a reinforcement system to achieve better strength. Its reinforcement and filling system is similar to that of general rubber. The reinforcing agent is mainly carbon black and white carbon black. White carbon black can improve the tear resistance of CPE and can form a meta-white system to improve the adhesion between CPE and the skeleton. CPE has high filling properties, and the filling system mainly includes calcium carbonate, talcum powder, clay, etc.
Plasticizer system
Ester plasticizers and aromatic hydrocarbon plasticizers are the most commonly used plasticizers for CPE, such as dioctyl terephthalate (DOTP), dioctyl adipate (DOA), aromatic oil, etc. Their solubility parameters are close to CM and their compatibility is good. Dioctyl phthalate (DOP) has been discontinued due to environmental issues. DOA and DOS can be used in rubber to give the rubber excellent cold resistance. DOS is very suitable for situations where both heat resistance and low temperature resistance are required.
Stable protection system
CPE will release hydrogen chloride when heated or vulcanized (non-peroxide vulcanization system), so a stabilizer with acid absorption effect should be used in the formula, such as calcium stearate, barium stearate, tribasic lead sulfate or magnesium oxide.
Vulcanization system
CPE is a saturated rubber, and the general ordinary sulfur vulcanization system cannot effectively vulcanize it.
The vulcanization system is divided into four major vulcanization systems: 1. Thiourea system, 2. Peroxide system, 3. Thiadiazole system, 4. Triazole dithioamine salt system.
1. The thiourea system was used relatively early in the CPE vulcanization system, among which Na-22 is the most effective. However, Na-22 has a slow vulcanization speed, poor aging performance, and high compression permanent deformation. Moreover, Na-22 is a serious carcinogen and produces an unpleasant odor during vulcanization. Its use has been restricted abroad.
2. At present, the most mature CM vulcanization system is the peroxide vulcanization system, which has a faster vulcanization speed, good product physical properties, and small compression permanent deformation. The peroxide system can be used in the production of tapes, and the products have good physical properties, heat resistance, and oil resistance. When the system is combined, adding co-crosslinking agents such as TAIC, TAC, TMPTM, and HVA-2 can significantly improve its physical and mechanical properties and heat resistance. Since peroxides are crosslinked by free radical reactions, some acidic fillers will affect the generation of free radicals, so such fillers should not be used. However, peroxide is not suitable for moldless vulcanization under low pressure, and has high process requirements, making it difficult to apply to most rubber product processes.
3. EataMix TCHC is a compounded CPE-specific vulcanizer, which is non-toxic. TCHC can use cheap aromatic oil as a plasticizer, and the vulcanized rubber has excellent performance. The activity of MgO has little effect on the physical properties and aging properties of TCHC system vulcanized rubber. Ultrafine Mg(OH)2 as an acid absorber is equivalent to high-activity magnesium oxide with an iodine absorption value of 150, which can replace expensive imported high-activity magnesium oxide and greatly reduce manufacturing costs.
The application cost is much lower than that of foreign thiadiazole systems, and it can be applied to various vulcanization processes, including low temperature, moldless, pressureless and low-pressure vulcanization. This system has a faster vulcanization speed, excellent physical properties of the vulcanized rubber, low compression permanent deformation, good resistance to heat oxygen, ozone aging, and oil resistance. It is also an effective co-crosslinking system for CPE and diene rubber, and has been successfully applied in the hose industry. TCHC vulcanization speed is slower than peroxide, but it can be vulcanized at lower temperature, without pressure and mold, and the vulcanized rubber has excellent performance.
The thiadiazole system is mainly composed of crosslinking agent and accelerator. The main crosslinking agents are ECHO.A, ECHO, TDD, PT75, TDDS. The main accelerators are Vanax 808, EataAccelDH, NC, Accel 903, BF. It is a class of additives with great development prospects.
4. Triazole dimercaptoamine salt system.Triazole dimercaptoamine salt vulcanizer is a single substance that integrates the effective groups of thiadiazole vulcanizer and accelerator (n-butyraldehyde and aniline condensate), which overcomes the irregular distribution of bonds after thiadiazole and accelerator crosslinking rubber, making the rubber crosslinked body a stable structure. Compared with the thiadiazole system, the salt also changes the pH value of the system due to the introduction of special groups, from strong acid to neutral, changing the adverse effects of acidic fillers on the system, making the rubber more chemically active during crosslinking. Therefore, the physical and chemical properties of the cross-linked CPE rubber of this system have been qualitatively improved. Aromatic oil, magnesium oxide and magnesium hydroxide can be used as raw materials, which are suitable for low-temperature pressureless and low-pressure vulcanization process conditions. The vulcanization speed is fast, which is faster than that of thiadiazole. The addition amount is small (2 parts), the unit price is favorable, it does not decompose within the vulcanization temperature, does not produce odor, and is environmentally friendly and non-toxic.
