Abrisa Technologies and its divisions have the engineering, manufacturing and customer service teams needed to service your optical requirements. Our vast knowledge base and years of industry experience allow us to deliver high quality optics for a one-off requirement or for large scale OEM production quantities. Abrisa Technologies' High Ion Exchange or HIE glass is chemically strengthened glass that has increased strength as a result of a post-product chemical process. Abrisa's Chemical Strengthening process toughens soda lime through a sodium and potassium ion exchange in a salt bath. Glass can be strengthened from 8 to 16 hours and is often requested for toughened thin display applications. Heat Tempering toughens soda lime through the controlled heating and cooling of the glass to maintain a temperature differential between the core and outer surfaces. The stresses induced compress the outer surfaces, forming a substrate substantially tougher than standard soda lime.
