| Abstract: | Cast PU elastomers were prepared from polycaprolactone diol, tetrahydrofuran - propylene oxide copolyether, TDI, MOCA, etc. The effects of polycaprolactone - copolyether proportion, NCO contents, plasticizer versus MOCA ratio on mechanical properties of PU elastomers were studied. The mechanical properties of PU elastomers prepared with optimum process are Shore hardness 57 - 58, 300% modulus 3. 8 - 3. 9 MPa, tensile strength 18. 5 - 19. 2MPa, elongation at break 450 - 460%, tearing strength 28 - 30 kN/m. |
