Electrically Conductive Flexible Polyurethane Adhesive Polytec PU 1000

Intertronics announced its Polytec PU 1000 electrically conductive flexible polyurethane adhesive. Polytec PU 1000 is a single part adhesive that cures quickly at room temperature to a flexible, electrically conductive polymer. It can replace traditional epoxies that are rigid and require thermal processing

Polytec PU 1000 is a single-component, silver filled, paste adhesive, which can be both stored at room temperature and cured quickly at room temperature. It is flexible and elastic, which makes it ideal for bonding of flex-circuits, temperature-sensitive substrates or substrates with highly dissimilar coefficients of thermal expansion.

The Polytec PU 1000 electrically conductive flexible polyurethane adhesive also is ideal for applications in die attach, bonding of components in hybrid circuit applications and surface mount technology (SMT). This adhesive can be an alternative to 2-part epoxies.

The simplicity of using a one-part application without mixing and an indefinite pot life with rapid cure at room temperature (10 minutes at 23°C) delivers manufacturing process advantages over 2-part epoxy solutions.

Performance of PU 1000 electrically conductive flexible polyurethane adhesive is considered excellent for the electrical contact of both active and passive components, especially when coupled with its ease of processing and high flexibility. The adhesive can be dispensed automatically or applied manually and has rheological properties which are suitable for the requirements of the jet type dispensers. It is suitable for electrically conductive bonding and coating applications on absorbing substrates like fabric, paper, leather, cork and non-absorbing substrates like glass, ceramics, PMMA, metals and most plastics.
