Polyolefin polymers have been an important part of daily life for variety of applications since the reported lab-scale process by Carothers in the 1930s1 and commercial process introduction by ICI in the 1940s.
Solvents have traditionally been derived from petroleum. These petroleum-based solvents are now being replaced by bio-based solvents, derived from renewable feedstocks such as corn, soybeans and orange peels.
Meter/mix systems vary immensely from application to application. Adhesive or sealant resin formulations can vary as well—by chemistry, viscosity, filler content, handling time, and moisture sensitivity, as well as other critical performance factors engineered by the material supplier.
As a response to the multiple definitions of hazard—and multiple ways of communicating these hazards—the United Nations adopted the Globally Harmonized System for Classification and Labeling of Chemicals (GHS) in 2003.
Ultraviolet (UV) light-emitting diode (LED) curing offers many benefits for bonding and coating applications in the touchscreen manufacturing segment. It provides a more consistent and reliable process without damaging or discoloring heat-sensitive components.
