Special‑shaped Polyurethane Parts
Composite‑molded with polyurethane and metal substrate, featuring strong adhesive‑layer bonding force, resistance to delamination and cracking under high‑frequency usage, and no workpiece scratching during wiping. Hardness, thickness and substrate material are customizable. It is widely applied for residual adhesive removal and surface wiping in coating and printing equipment.
核心优势
-
Strong Adhesion for Composite SubstratesHigh‑performance polyurethane‑aluminum alloy composite molding: uniform‑elasticity rubber layer, adjustable wiping force for scratch‑free workpieces. Sandblasting pretreatment improves bonding to resist degumming and cracking under long‑term high‑frequency use.Strong Adhesion for Composite Substrates -
Full‑dimensional flexible customizationAdhesive layer hardness, thickness and formula are adjustable for varied wiping force, solvent‑ and temperature‑resistance. Mounting interfaces and dimensions fit diverse coating, printing and web‑handling equipment; full‑spec custom development available.Full‑dimensional flexible customization
