Applications     5 or 6 2 amino 1, 3, 2 hydrocarbon replacing uracil as PVC stabilizer has good effect, stable to absorb release of hydrogen chloride gas, PVC degradation process can replace PVC molecular chain unstable chlorine atoms and inhibit the degradation of PVC, and can replace unstable chlorine atom, slow down the ageing process of polyvinyl chloride (PVC) speed, thus improve the thermal stability of PVC, improve the processing properties of PVC.
When 5,6 diamino1,3 dihydrocarbon substituted uracil is used together with zinc stearate and calcium stearate, it can produce synergistic effect, significantly improve the thermal stability of PVC, and make PVC have better stability effect.
