METHOD OF MANUFACTURING ELASTIC FOAMED MATERIAL Russian patent published in 2003 - IPC

FIELD: polymer materials. SUBSTANCE: manufacture of elastic foamed material suited to be used in motorcar construction, furniture industry, and in sports equipment production consists in foaming isocyanate-containing product (urethane prepolymer) in presence of latex with at least 20% solids at weight ratio (80-20): (20-80) using vulcanization group including sulfur, thiuram, Captax and/or Altax so that indicated components are present in following amounts, wt parts: prepolymer 80-20, latex 20-80, sulfur 0.03-0.24, thiuram 0.005-0,017, and Captax and/or Altax 0.005-0.05. EFFECT: improved physicochemical characteristics due to strengthened base polymer. 2 tbl, 12 ex
