Recycling Polymers MATSE 81 Materials In Todays World

Thermosetting polymers are much more difficult to recycle Some of them can be ground up and used as filler for other processes and on a casebycase basis some can be processed to be broken down into their underlying base units which can be reused Another approach to reducing the amount of plastic that ends up in our landfills is the

An Investigation of Siloxane Crosslinked Hydroxyapatite

Jan 01 2012 · Causes of bone deficiency are numerous but biomimetic alloplastic grafts provide an alternative to repair tissue naturally Previously a hydroxyapatitegelatin modified siloxane HApGemosil composite was prepared by crosslinking N N′bis3trimethoxysilylpropylethylene diamine enTMOS around the HApGel nanocomposite particles to mimic the natural composition and properties of bone
