The product "High Quality Polyethylene, Chlorinated Cas 63231-66-3 / 64754-90-1 With Best Price" is a type of chlorinated polyethylene. Chlorinated polyethylene (CPE) is a synthetic rubber produced by the chlorination of high density polyethylene (HDPE). The CAS numbers 63231 - 66 - 3 and 64754 - 90 - 1 are important identifiers for this chemical substance in the chemical industry.
Physically, it is usually in the form of a white powder. It has good chemical stability and excellent resistance to weather, ozone, and heat. The degree of chlorination can vary, which affects its properties. Generally, the chlorination level can range from 25% to 48%, and different chlorination levels are suitable for different applications.
Chlorinated polyethylene has a wide range of applications in various industries.
In the plastics industry, it is used as a modifier for polyvinyl chloride (PVC). When blended with PVC, it can improve the impact resistance, weatherability, and processing performance of PVC products. This makes it suitable for manufacturing PVC profiles for windows and doors, pipes, and cables.
In the rubber industry, it can be used as a substitute or a blending component for various rubbers. Its good oil - resistance and weatherability make it suitable for manufacturing rubber products such as hoses, seals, and gaskets.
It is also used in the coatings industry. Chlorinated polyethylene - based coatings have excellent adhesion, corrosion resistance, and weatherability, which are suitable for protecting metal surfaces, concrete structures, and other substrates.
When using chlorinated polyethylene, it is important to follow proper procedures. In the blending process with other polymers, it is necessary to ensure uniform mixing. For example, when blending with PVC, a twin - screw extruder can be used. The temperature and speed of the extruder should be adjusted according to the specific properties of the materials and the requirements of the final products.
When using it in the rubber industry, it needs to be compounded with other rubber additives such as vulcanizing agents, accelerators, and fillers. The compounding process should be carried out in a mixer with appropriate temperature and time control.
In the coatings industry, it should be dissolved in appropriate solvents to form a coating solution. The concentration of the solution, the method of application (such as spraying, brushing), and the curing conditions need to be carefully determined according to the specific coating requirements.
Case 1: PVC Window Profiles
A PVC profile manufacturing company used our chlorinated polyethylene as a modifier for their PVC window profiles. Before using our product, their profiles had relatively poor impact resistance, especially in cold weather. After adding our chlorinated polyethylene with an appropriate chlorination level, the impact strength of the profiles increased significantly. The profiles passed the strict impact tests in cold regions, and the company's market share in the cold - climate areas expanded.
Case 2: Rubber Hoses
A rubber hose manufacturer incorporated our chlorinated polyethylene into their hose production. They found that the hoses had better oil - resistance and weatherability compared to the previous products. The hoses were used in automotive engine compartments, where they were exposed to oil and harsh environmental conditions. The improved performance of the hoses led to longer service life and fewer replacement requirements, which was well - received by automotive manufacturers.
Case 3: Anti - Corrosion Coatings
A company specializing in anti - corrosion coatings used our chlorinated polyethylene as a main component of their coatings. They applied the coatings on metal structures in a coastal area. After several years of exposure to the salty and humid coastal environment, the coatings still showed excellent corrosion resistance, protecting the metal structures from rusting and damage.
