High Density Shoe Shaping Foam Sheet

This high‑density closed‑cell shaping foam sheet features dense uniform closed‑cell foaming structure with excellent three‑dimensional supporting rigidity, delivering stable shaping effect after thermal‑press compounding with hot‑melt adhesive film to effectively prevent toe‑box collapse, heel shrinkage and shoe‑collar deformation during long‑term shoe wear.

Combining great toughness and compression resistance, it leaves no permanent indentation after repeated squeezing and bending of uppers, and avoids cracking, powdering and thickness attenuation even after thousands of walking‑flexing cycles so as to extend the service life of finished shoes, its foam pores are evenly distributed with smooth flat surfaces free of dents, bulges and uneven‑thickness defects, generating neat clean edges after die‑cutting without shedding foam debris during cutting, hot‑pressing and sewing in workshops and reducing secondary cleaning workload, meanwhile it boasts excellent hot‑melt lamination compatibility and can closely bond with low‑temperature TPU hot‑melt adhesive film under standard hot‑press temperature without blistering or delamination, achieving stable adhesion with fly‑knit fabric, microfiber, PU leather and other upper materials.

Manufactured with low‑odor eco‑friendly foaming formula without pungent volatile substances and formaldehyde, it satisfies international footwear low‑VOC safety standards for export‑order production, serving as dedicated supporting consumable for sports‑shoe factories, casual‑shoe plants, safety‑work‑shoe workshops and shoe‑material wholesalers, it can be cut into arbitrary shapes as toe‑puff, heel‑counter support pad and shoe‑collar lining reinforcement, which is thermally compounded with TPU hot‑melt film and attached to inner uppers to provide rigid support and maintain shoe silhouette for running shoes, dad shoes, skate shoes, casual footwear and industrial safety shoes.

During processing, lay foam sheets flat on cutting tables and rest 10‑15 minutes to release internal stress from warehouse compression before layout and die‑cutting to avoid dimensional deviation, conduct small‑sample hot‑press tests with matched low‑temperature TPU hot‑melt film before mass production and fine‑tune temperature, pressure and holding time to ensure tight bubble‑free lamination, do not over‑stretch foam sheets to prevent uneven local density and shaping failure of finished shoes, stack cut blanks flat and avoid long‑term vertical heavy compression against permanent indentation and reduced supporting rigidity; seal residual full‑size sheets with waterproof dust‑proof film after daily processing to avoid dust contamination affecting hot‑melt bonding, store sheets horizontally on flat shelves in cool dry well‑ventilated warehouse below 35 ℃ away from high‑heat sources, direct sunlight, oil stains and corrosive solvents to prevent pore aging, hardness drop and discoloration, never stack heavy steel plates or cartons on foam sheets to avoid permanent damage to inner pore structure, and wrap unused sheets with dust‑proof PE film to protect bonding performance.

Material maintenance includes daily pre‑production inspection of flatness, thickness uniformity and debris‑shedding condition, weekly sampling tests on density, compression resistance, flexural toughness and hot‑melt compatibility for new batches, as well as monthly classified check for long‑stocked sheets with discolored or deformed ones prioritized for production, properly control hot‑press temperature to avoid foam surface melting and structural damage caused by overheating.

Cutting trimmings can be centrally recycled and reprocessed into industrial foam pellets for low‑carbon circular production, this PU‑EVA composite closed‑cell foam supports customizable density from 180 kg/m³ to 350 kg/m³, mainly used for toe‑box, heel and shoe‑collar reinforcement of sports shoes, its closed‑cell structure balances compression performance and toughness without permanent deformation or supporting‑force loss after repeated bending, features perfect adaptability to low‑temperature TPU hot‑melt film for seamless blister‑free lamination, adopts low‑odor formaldehyde‑free low‑VOC formula complying with global export‑shoe‑material environmental requirements, comes in standard sheet size 1000 mm×2000 mm for automatic die‑cut layout with 20 pieces per standard export carton.
