In industrial and consumer applications, hoses and tubing must withstand demanding conditions, including mechanical stress, chemical exposure, and varying temperatures. Chlorinated Polyethylene (CPE) is a highly adaptable polymer additive that significantly improves the performance characteristics of hoses and tubing. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of specialized chemical raw materials, details the key advantages of using CPE in these critical applications.

CPE: A Solution for Enhanced Hose and Tubing Performance

CPE, supplied as a fine white powder, is a saturated elastomer formed by the chlorination of polyethylene. This modification imbues it with a robust set of properties that make it ideal for use in flexible polymer products:

  • Excellent Low-Temperature Flexibility: CPE remains flexible even at very low temperatures, which is crucial for hoses and tubing used in cold environments or applications involving fluids that can freeze. This property ensures the product does not become brittle or crack under stress.
  • Good Oil and Chemical Resistance: CPE exhibits resistance to a wide range of oils, greases, fuels, and chemicals. This makes it an excellent choice for fluid transfer applications where exposure to such substances is common, such as in automotive fluid lines or industrial chemical transfer hoses.
  • Abrasion and Tear Resistance: CPE offers good mechanical properties, including resistance to abrasion and tearing. This durability is essential for hoses and tubing that may be dragged, flexed, or exposed to physical wear.
  • Weatherability and Ozone Resistance: For hoses and tubing used outdoors or in environments with high ozone concentrations, CPE’s inherent resistance to UV radiation and ozone degradation ensures a longer service life and maintained performance.
  • Flame Retardancy: The chlorine content in CPE provides a degree of flame retardancy, which can be beneficial in specific applications where fire safety is a consideration.
  • Compatibility: CPE demonstrates good compatibility with various base polymers, including PVC, NBR (Nitrile Butadiene Rubber), and EPDM, allowing formulators to create compounds with tailored properties.

Applications of CPE in Hoses and Tubing

The superior properties of CPE make it a preferred additive for a variety of hose and tubing applications:

  • Automotive Hoses: Used in fuel lines, oil cooler hoses, and power steering hoses due to its oil and fuel resistance and good low-temperature flexibility.
  • Industrial Hoses: Suitable for transferring chemicals, air, water, and hydraulic fluids in various industrial settings, benefiting from its chemical resistance and durability.
  • Consumer Tubing: Employed in garden hoses, appliance tubing, and other general-purpose flexible tubing requiring durability and flexibility.
  • Wire and Cable: While also used in jacketing, CPE's flexibility and resistance properties are beneficial for certain types of wire and cable insulation as well.
