DESCRIPTION
EMS Griltex produces speciality copolymer adhesives for use in the composites sector. EMS products are ideal for the production of thermoplastic composites via the RTM process and for the reinforcement of woven carbon, glass, basalt and aramids. They offer great toughening properties in finished epoxy composites and improved CAI, delamination and peel strength performance.

Properties
Stabilising of unidirectional filaments
multiply, woven and knitted fabrics
nonwovens
⇒ Better and easier handling
⇒ Antifray
⇒ Gluing of multiple layers to one component
⇒ Production of preforms without additional auxiliaries

Mechanical Benefits Peeling Force
Polymers are insoluble in Epoxi resin
⇒ Maintain the Tg of Epoxi-matrix
High peeling forces between Griltex High Performance Polymers and epoxi-resins
⇒ Maintain adhesion from Epoximatrix to fibers.
