Aggression Polyurethane Liners

Polyurethane wear plates are steel backed, the steel is bonded with polyurethane to prevent fines penetrating behind the liner plate, thus preventing bulging of the liner which can otherwise cause liner dislodgement. These liners are a harder material compared to rubber but softer than plastic, therefore providing an excellent degree of abrasion resistance together with flow ability.

Poly liners perform very well in wet applications with fine particles and sliding wear.

Polyurethane liners are a synthesis of polyols and isocyanides chains extended or cross linked into giant molecular complexes. This material has the combined properties of rubber and plastic.

Aggression UHMWPE

Ultra-High Molecular Weight Polyethylene (UHMWPE) is a resin-based product having molecular weight greater than 4million gm. /mol. It is important that we do not confuse UHMWPE with High-Density Polymer (HDPE) because HDPE does not exhibit superior wear characteristics as UHMWPE due to its lower molecular weight.

As the molecular weight of polyethylene increases, its abrasion resistance and non-stick characteristics are enhanced. These liners are extensively used all over the world as ideal flow promotion liners.

UHMWPE Application areas include:

  • Chutes
  • Silos
  • Bins
  • Launders

Available in custom sizing.
