  • What are chlorinated polyethylene elastomers (CPE)?
  • Chlorinated polyethylene elastomers (CPE) are produced from high density polyethylene (HDPE) that is randomly chlorinated in an aqueous slurry. Polymers are differentiated by chlorine content, molecular weight and crystallinity. Chlorine contents generally range from 25 to 42 percent.
  • Are ester plasticizers compatible with eco?
  • Ester plasticizers are compatible with ECO where the plasticizer has a similar polarity to that of the polymer. DOP, DIDP, and, TOTM are common choices. Most ester plasticizers cannot withstand the post-cure cycles and temperatures typically sued with FKM.
  • Which plasticizer is best for eco?
  • For example, if low temperature flexibility is required an ester plasticizer such as DOS or DUP might be considered. TOTM might be a good choice is both low temperature properties and high heat applications are desired. Plasticizers can be used to improve properties in ECO.
  • What types of plasticizers are used in CPE?
  • The amount and type of plasticizers used in CPE formulations are similar to that of PVC, including adipates, phthalates, and trimellitates. Common choices include general plasticizers such as DINP, DOP, and DOTP. Specialty plasticizers such as DOA, DINA, DBS, DOS, TOTM, and TINTM can be used as well.
  • Which plasticizers are used in elastomer compounds?
  • Common plasticizers used in elastomer compounds are mineral oils and esters such as phthalates, sebacates, and adipates. However, plasticizer selection is largely dependent on which elastomer (s) is used and what the desired outcome is.
  • Are standard polymeric elastomers suitable for low temperature performance?
  • Standard polymeric esters are well known for their permanence in these elastomers, but are insufficient at im-proving low temperature performance. The esters tested in this study are lower molecular weight esters that have high heat resistance, but provide much needed low temperature flexibility, both before and after high heat-aging.
