At Electronica 2016, Rampf Polymer Solutions will debut a new portfolio of polyurethane (PU) electro casting resins with superior thermo-mechanical properties.
Thermal shock – shock-like temperature variations linked with the thermal expansion coefficient of materials – can lead to fractures in contacts and cables, cracks in the resin, and cause gaps to open up between the resin and plastic parts in sensitive and complex electronic and electrical components such as electronic control units and sensors.
To increase electrical/electronical components’ resistance to thermal shock, Rampf Polymer Solutions has developed RAKU-PUR, a portfolio of PU electro casting resins whose thermo-mechanic properties have been confirmed in dynamic-mechanical analyses (DMAs).
The resins ensure a long lasting resistance to temperature variations in an application temperature range of -40°C to +130°C.
Because of the use of non-abrasive fillers, the RoHS-compliant, RTI-listed PU systems can be processed on standard two-component mixing and dispensing systems. Systems are also available in a flame retardant version according to UL 94 V0.
Rampf will also be featuring extremely clear adhesives for the optical bonding of displays.
Optical bonding involves bonding two mostly transparent materials using extremely clear adhesives. The company has developed the so called Liquid Optically Clear Adhesives (LOCA), which is optimized for industrial-scale processing on mixing and dispensing systems.
These silicone-based adhesives cure at room temperature, are available in various hardnesses and viscosities (from liquid to thixotropic).
Electronica 2016 will take place in Munich, Germany from November 8-11.
