Natural rubber mixing mill plasticate, roller temperature for 30 to 40 ℃, time of about 15 to 20 min; The mixer plasticate when the temperature is above 120 ℃,Custom Mold Rubber Parts time of about 3-5 min.

　　The viscosity of butadiene rubber is between 35 and 60. Therefore,Rubber O-Ring the styrene butadiene rubber can not be used as a plasticizer, but it can improve the dispersibility of the machine after the plasticizer

　　Shunding rubber has cold flow and lacks the effect of plasticities. The viscosity of shunding gum is lower, Rubber Gasket but it is not plastic-smelting.

　　Neoprene large plastic, can be BoTong 3-5 times before plastication, BoTong temperature in 30 to 40 ℃.

　　The molecular main chain of ethylene-propylene rubber is a saturated structure, Rubber Seal and the plasticized process is difficult to induce the cracking of the molecules. Therefore, it is important to choose the varieties with low viscosity and not plasticized.

　　The butyronitrile rubber can be small in plasticity, large in toughness and large in plastication. Low temperature 40 ℃, the following should be used when mixing small roller distance,Rubber Parts low capacity, and segmented plasticate, so that you can receive better effect.
