This paper covers the experimental investigation on creep for polypropylene material with constant and varying load conditions. In first condition with the help of load hanger a constant load was applied till the specimen breaks and in second condition using tensile helical spring and turnbuckle arrangement, a constant reducing load with respect to time was applied till the specimen breaks. The specimen was subjected to a load of 30 Kg at 700c and 50Kg at 750c. The result shows that the creep behavior is significantly a time dependent phenomenon. The result also shows that using tension helical spring and turnbuckle arrangement the specimen deflection itself reduces the applied load with respect to time.
