2、 Apply
Compared with other brands, yh-604 has excellent compression permanent deformation resistance, balanced mechanical properties and melt flow performance of elastomer under high filling, and maintains good flexibility and hardness in the temperature range of - 50 ~ 90 ℃. It can process parts with various complex structures and is suitable for producing sealing strips for buildings, automobiles and electrical appliances.
The typical properties of the elastomer obtained by blending 100 phr yh-604, 120 phr 26# white oil and 40 phr polypropylene are as follows:
Tensile strength at break: 9.0MPa
Shore a hardness: 60
Elongation at break: 700%
300% constant extension stress: 3.0MPa
70℃ × 24-hour compression set: < 35%
200 ℃, 2.25kg yard (die 2.06mm), melt flow rate G / 10min, 0.6
