The Energy of Break or Deformation in Some Semi- Crystalline Polymers
energy to break
extension rates
polypropylene (PP)
high density polyethylene(HDPE) and low density polyethylene (LDPE).
The aim of the current study is the investigation of tensile behavior of the semi - crystalline polymers : polypropylene (PP ) , high density polyethylene(HDPE) and low density polyethylene (LDPE) . The energy to break or deformation was determined as a function of extension rates , ( PP) was break at extension rate (5) mm/min but (HDPE) break at higher extension rates (25) mm/min while( LDPE) not break even at very high extension rates but it is deformation or failure .
