Chlorinated polyethylene is an amorphous polymer that is produced by chlorinating polyethylene (plastic bags, packaging etc.) to a chlorine content of 25% to 42%.
CPE displays great resistance to chemicals and oils as well as temperature resistance, weather resistance and good mechanical properties. CPE is soft and rubbery so is often combined with other polymers, such as polyvinyl chloride (PVC) to increase their impact resistance. CPE is also combustion resistant.
CPE displays low warp and shrinkage as well as good Z-axis adhesion. Whilst CPE displays low ultrafine particle emission and low odour when printing, it can release irritant emissions , such as hydrogen chloride, if it is being processed above its usual melt temperature. Always check the Safety Data Sheet before printing.
CPE has a print temperature range of 235°C to 260°C and usually requires a heated bed at or around 70°C. This will vary between brands so always check the Technical Data Sheet. A small brim will probably be needed to ensure good build plate adhesion.
CPE is a great filament to use for strong prototypes or final products that need good chemical resistance. Here at Filaments.directory you can select the right CPE filament using our constantly updated list of suppliers and our comprehensive search tool!
