Self-adhe­si­ve films

Self-adhe­si­ve films or items fit­ted with self-adhe­si­ve backings are beco­ming incre­asing­ly popu­lar in many are­as, par­ti­cu­lar­ly in various engi­nee­ring fields. They enable clean and easy assem­bly of a wide varie­ty of com­pon­ents. Self-adhe­si­ve films usual­ly com­pri­se two com­pon­ents: the car­ri­er and the adhe­si­ve. Eit­her of the­se can con­sist of a wide ran­ge of mate­ri­als. Adhe­si­ves can eit­her con­tain sol­vents or be sol­vent-free. Celloflex always uses sol­vent-free adhe­si­ves. Self-adhe­si­ve films or dou­ble-sided adhe­si­ve tapes essen­ti­al­ly use two types of adhe­si­ves: rub­ber res­in or acrylic adhe­si­ves. The­se are water-based disper­si­on adhe­si­ves. Bet­ween 40 and 70% of the water eva­po­ra­tes when app­ly­ing the adhe­si­ve.

Car­ri­ers can con­sist of a wide varie­ty of mate­ri­als, inclu­ding fibres or non­wo­vens but also sili­co­ne-coa­ted sepa­ra­ti­on films. A distinc­tion should be made bet­ween com­pon­ents or items equip­ped with self-adhe­si­ve backings (with the aim to attach the com­po­nent to ano­ther item using an adhe­si­ve) and mate­ri­als that include a non­wo­ven or simi­lar lay­er. Celloflex offers both opti­ons to pro­vi­de addi­tio­nal fea­tures or to make assem­bly easier when cut­ting foam to size.
