rubber and synthetic rubber. The use of this peptizer can improve the plasticity and efficiency of
rubber mastication, shorten the mastication time by about one-third, save energy and improve labor
production efficiency. It is an ideal high-efficiency and energy-saving rubber processing aid.
1. Product performance:
It is suitable for mastication at higher and lower temperatures. It can be used on open mills and
internal mixers. The low-temperature mastication temperature is 50-80, and the high-temperature
mastication temperature is 130-160. The physical machinery for rubber after plasticization There is no
adverse effect on performance and performance after aging.
This product is non-toxic, partially melted, almost insoluble in water and most organic solvents. At
room temperature, dry, moisture-proof and dark conditions, sealed storage for 10 months will have no
effect on product performance.
