1.MaterialPP Hollow plastic formwork: New PP (polypropylene)
PVC Formwork: PVC (Polyvinyl chloride)
PVC material viscosity is too low, plus the middle foam or wood powder filled, the middle part is easy to damage. The pp hollow plastic formwork is a kind of material with high viscosity, good toughness and no local damage.
2.StructuralPP Formwork: Hollow
PVC Formwork:Solid shape
In the process of concrete solidification, a lot of heat will be given off. The solid plate conducts heat through the material, and the plate will release heat variation at high temperature.Only one side of the pp hollow plastic formwork is heated, and air flows through it. The other side of the board is not affected by concrete solidification and heating
3.Minimum construction temperature
PP Formwork:-20℃
PVC Formwork:0℃
4.Vicat softening point
PP Formwork:115℃
PVC Formwork:65℃,will become soft and wavy
5.Reuse Time
PP Formwork: more than 60times
PVC Formwork:20-30 times.
6.Water absorption expansion ratePP Formwork: 0.4%
PVC Formwork:1%
PP Formwork will be more warerproof than PVC
7.Although PVC building formwork is harder than PP formwork, it is more fragile and can be easily damaged during construction
Summary
PP Hollow Plastic Formwork is the fifth generation of plastic building formwork,pvc is the third.
The quality is pp hollow plastic formwork better than PVC formwork, of course the price is also higher than PVC formwork.
