The polyurethane foam pig's length typically ranges from 1.75 to 2 times the pipe size, with a disturbance of around 25 mm or 5% to 10% of the pipe diameter. This design ensures high elasticity, strength, and notable wear resistance, with deformation capabilities exceeding 50%.

Foam Pig for Drying is made of low-density foam. Its main material is low-density polyurethane through mold foaming. The product density can also be customized. The product has the characteristics of tear resistance and good wear resistance. Also good resilience, and no blocking.
