In this study,the main components of the basic formula of hard PVC pipe and both the domestic and foreign fomula of it were investigated mainly through referring to lots of documents. the performance and specifications of PVC resin were presented ,main varieties and development trends of plastics additives ,such as thermal stabilizers, plasticizers, lubricants, fillers, Colorants were stated,focusing on the study the important role of plastic additives in the formula of PVC pipe . Based on this, through the design of experiments,the effects of different stabilizer on the performance such as thermal stability, rheological properties, Weathering resistance were studied, Thereby the optimizing of formula, improving of product properties, reducing of production costs were possible. My ability to analysis and sovle difficult problems may be improved through the current study of the formula.

The main method of study in this part is referring to the literature research,through which we acquaint ourself with the formular for Hard

PVC Pipe, and the main fundamental formular at Home and Abroad.
