From Adchem Corporation

TPO materials, with their low surface energy characteristics, present unique bonding challenges for manufacturers of pressure sensitive adhesives. Add into the equation a second substrate, such as, a foam, vinyl, other low energy surface finish or material and the bonding challenge increases. Adhesive tape construction and the adhesive used play a role in a successfully engineered bonding solution. TPO's engineered for specific applications will require the bonding system also satisfy the requirements of the application. Emerging interest in Low VOC adhesive systems further complicates bonding choices. Automotive interior and other industrial specifications will be impacted by Low VOC adhesive technology. Adchem will explore available adhesive chemistries, the challenges and solutions they provide for the TPO user.
