    • The present invention relates to blowing agent compositions comprising at least one hydrochlorofluoroolefin (HCFO) used in the preparation of foamable thermoplastic compositions. The HCFOs of the present invention include, but are not limited to, 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), particularly the trans-isomer, 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), dichloro-fluorinated propenes, and mixtures thereof. The blowing agent compositions of the present invention are used with coblowing agents including carbon dioxide, atmospheric gases, hydrofluorocarbons (HFC), hydrofluoroolefins (HFO), alkanes, hydrofluoroethers (HFE), and mixtures thereof. Preferred HFCs used as coblowing agents in the present invention include, but are not limited too, 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), pentafluorethane (HFC-125), difluoromethane (HFC-32). The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor.
    • 本发明涉及包含用于制备可发泡热塑性组合物的至少一种氢氯氟烯烃(HCFO)的发泡剂组合物。 本发明的HCFO包括但不限于1-氯-3,3,3-三氟丙烯(HCFO-1233zd),特别是反式异构体2-氯-3,3,3-三氟丙烯(HCFO -1233xf),二氯氟化丙烯及其混合物。 本发明的发泡剂组合物与包括二氧化碳,大气,氢氟烃(HFC),氢氟烯烃(HFO),烷烃,氢氟醚(HFE)及其混合物的助熔剂一起使用。 在本发明中用作起泡剂的优选的HFCs包括但不限于1,1,1,2-四氟乙烷(HFC-134a),1,1-二氟乙烷(HFC-152a),1,1,1-三氟乙烷 三氟乙烷(HFC-143a),五氟乙烷(HFC-125),二氟甲烷(HFC-32)。 发泡剂组合物可用于生产具有改进的k因子的低密度绝缘泡沫。
