Engineered for heavy, slow-moving equipment where no deflection is wanted or needed. Maximum stability and rigidity — the safety-first formula for cranes, military, and mission-critical operations.
Poly-Fil® HP is a two-component polyurethane flatproofing system consisting of a prepolymer Side-A (ISO) and a polyol blend Side-B (CAT). It is specifically engineered for heavy, slow-moving equipment where no deflection is wanted or needed — prioritizing safety and structural integrity above all.
For stratocranes, high-reach equipment, and other applications where tire deflection poses safety risks, Poly-Fil® HP provides the firm, stable foundation that operators and safety managers require. No movement. No give. No compromise.
Poly-Fil® HP is formulated to provide maximum rigidity with no tire deflection under load — the critical requirement for cranes and high-reach equipment where stability determines safety.
In applications like man lifts and stratocranes, tire deflection can directly impact equipment stability and operator safety. HP eliminates that variable entirely.
Engineered specifically for the loads and operating conditions of heavy industrial equipment — HP handles the demands of mining, port, and steel mill environments.
Applied using a Poly-Fil® Maverick or Hulk II application system, HP's ISO prepolymer and polyol blend combine to form a firm, stable solid fill that never requires inflation.
