| Resistance degree limit, heat - NEOPRENE has a practical high temperature, continuous use of 80 ~ 95 ℃, in this range, it shows good physical properties, dragon's between the use of words, special formula can be reached 120 ℃, more than the limit will not make NEOPRENE softening or melting, but may cause hardening or loss of elasticity. Cold - in - 20 ℃ to 25 ℃ below zero use, performance only slight change, lower than the temperature is in brittle temperature, (40 ℃) gradually before hardening, special formula is allowed to use low temperature up to 55 ℃ below zero. |
