Form made from recycled resin

Abstract

Provided is a form for use in placing concrete, which is made from a recycled resin composition including a recycled polyester resin, a lactone polymer, an epoxidized diene based block copolymer, and optionally a polyolefin resin. The form can be made extremely advantageously from the view point of production cost since it utilizes a recycled resin such as waste PET. Further, the form is easy to set up and to remove after the placement of concrete when a support is used for setting. The form for use in placing concrete according to the present invention is improved in formability and has excellent mechanical strength.
