VERBESSERTE ELASTOMERE AUTOSCHLÄUCHE

摘要

Elastomeric vehicle hoses based on ethylene, alpha-olefin, vinyl norbornene elastomeric polymers will exhibit improved cure state and improved long term heat aging. Long term heat aging is an important consideration, as vehicle lives get longer and under the hood temperatures get higher. Also, such elastomeric based hoses will have improved compression set under a wide range of service temperatures. Such excellent compression set values lead to improved sealability over a wide temperature range. Additionally, these elastomeric polymers exhibit lower compound viscosity leading generally to improved processability.
