Mold foaming, rotary cutting, uniform thickness. Rotary cutting seamless technology standardized fully automatic process production, precise control of product thickness (thickness error is only ±0.1mm).
◎Mold foaming, rotary cutting, uniform thickness. Rotary cutting seamless technology standardized fully automatic process production, precise control of product thickness (thickness error is only ±0.1mm).
◎Factory prefabrication ensures flatness and seamless integration! The material does not deform, warp, arch, or crack.
◎High-density polymer products have excellent elasticity and shock-absorbing functions. It is resistant to compression deformation, bending and friction.
◎Good durability, no displacement cracking due to thermal expansion and contraction; high and low temperature resistance, the material can adapt to ambient temperatures of -40℃ to 80℃ after curing.
◎Excellent mechanical properties, elongation at break reaches 2 times the standard of GB36246-2018, and tensile strength reaches 1.5 times the standard of the new national standard.
◎100% of on-site sampling passes the new national standard.
◎Factory prefabricated products do not require any auxiliary materials to be added during construction, greatly shortening the construction period.
