Phlex Tek provides fiber sizing chemistry expertise in the following categories:
Waterborne phenoxy resins are the backbone of high performance sizes for chopped carbon fiber as it provides superior adhesion between the carbon fiber, which has a high polar surface, and the matrix resin of the composite – thermoset or thermoplastic. End-use applications such as polycarbonate and nylon molded components benefit from phenoxy-sized fiber with resultant superior physical properties.
Glass & Basalt Fiber
Phlex Tek offers neutralized, stabile waterborne polyesters for glass and basalt fiber production.
The phenoxy resin is an excellent adhesive/tie layer between multi-layer composites such as automotive headliners, food packaging films, graphic art substrates, laminated non-wovens, and other laminated substrates. Structural adhesives are enhanced and strengthened by the Phenoxy resin as it acts as both an adhesion promotor and flexibilizer in rigid epoxy and epoxy-urethane systems. The presence of phenoxy reduces stress cracks and increases bond strength between substrates.
