Power cord manufacturers to produce power cords used in the production of PVC plug material formula composition ratio and the quality of the power cord plug has a very strong relationship.

First of all, let's take a look at the ordinary PVC sheathed power cord rubber, plasticizer dosage of 50-60 kg, calcium-zinc stabilizer 4-6 kg, lubricant 0.5-1.0 kg, filler 50-65 kg.Now in order to reduce costs will be appropriate to participate in other plasticizers 6-10 kg; filler dosage is large, plasticizer, lubricant dosage can be larger; the use of inactive filler, plasticizer, lubricant dosage should be larger;

For ordinary power cord plug material, the amount of plasticizer is 35-60 kg, stabilizer 6-8 kg, lubricant 0.8-1.8 kg. 8 kg, filler 25-50 kg; plasticizer, lubricant dosage refer to the sheath level plug material. If the need for flame retardant PVC plug material, should be selected composite flame retardant system is appropriate not to use antimony trioxide will affect the fluidity, the amount of 3-6 kg; high-temperature PVC plug material in addition to the selection of high-temperature plasticizers should also increase the amount of stabilizers, and then add 0.6 kg of antioxidant, and appropriately reduce the filler in order to increase the fluidity.

For high insulation requirements of the power cord plug material, you have to use calcined clay filler; the development of a high degree of polymerization of power cord PVC plug material formulations, should be selected to use composite processing modifiers to improve its processing performance.
