Description

Prestressed plastic bellows is a new prestressed pore-forming material produced from HDPE and PP. It is mainly used in post-tensioned prestressed concrete structure Bridges, with good sealing performance, no bleeding, high ring stiffness, small friction parameters, aging resistance, corrosion resistance, large bending, not easy to be smashed by vibrator, easy to implement vacuum grouting to improve the service life of Bridges.
