Hollow Plastic Formwork (Shuttering) is though to conventional PP materials were modified by polymer additives, which improves the hardness of the template while ensuring its toughness. According to our experience and test report, our hollow plastic shuttering can be recycled up-to 50 times, the strength can reach to 3200MPa, the deformation rate is within 2mm and the diagonal line is within 0.5mm, which better meets the construction needs.It is a new type recycled construction build material.
