PLENSETTM
Drop impact resistance type
What is the PLENSETTM Drop impact resistance type?
Generally, epoxy resins are hard and brittle, but with our proprietary compounding technology, we have succeeded in creating a flexible composition. This results in improved impact resistance, stress alleviation, and stronger, more flexible joints.
Have you experienced these issues?
Here is the product that resolves these issues.
PLENSETTM Drop impact resistance type
Application
Adhesion to parts subject to shock and vibration
Adhesion to dissimilar materials and those that are difficult to bond (engineering plastics such as LCP and PA9T, metals such as gold and nickel)
Adhesion and bonding to flexible substrates, displays, and other components that require flexibility
Adhesion and encapsulation of thin-film components without warping or deformation
It can be used in a variety of situations.
Drop impact resistance through stress relaxation
It can be cured at a low temperature of 80degC, unparalleled for a one-component epoxy resin.
Vibration suppression and damping
Once cured, it gains a rubber-like elasticity, providing flexibility that is effective for stress alleviation as well as shock and vibration absorption.
Flexural resistance, low warpage
Due to its low elasticity, it has high peel strength and is effective for bonding dissimilar materials with large differences in linear expansion coefficients.
Product details
Flexibility test method for cured materials: JIS K7161 compliant
The drop impact resistance type exhibits a rubber-like flexibility.
Warpage in molding wafers
Wafer: 12 inches, 0.8 mm thick Mold: 0.4 mm thick
Warpage does not occur with the drop impact resistance type even when molding on one side of the wafer.
