Effects of Vulcanization System on Hardness of Elastomeric Materials under Various Temperatures |
초록 |
The effects of vulcanization system on the hardness of elastomer compounds were investigated as a function of temperature. Elastomres were compounded with various sulfur and peroxide content. In the sulfur-cured system S-S linkages are formed, and in the peroxide-cured system C-C linkages are formed. A newly designed IRHD-type hardness tester was used to investigate the hardness of elastomers. The crosslink density was calculated using the Flory-Rehner equation by the swelling method. The increase in the modulus of elastomer with increase in temperature above Tg is related to an increase in entropy. The results show that the hardness increased with increasing the crosslink density and temperature. |
