 · Fichier PDF

mechanical polishing (CMP) of PC and PMMA substrates was investigated. Four types of slurry were tested on CMP of the polymers under the same process conditions. The slurry suitable for polishing PC and PMMA was then chosen, and further CMP experiments were carried out under different process conditions. Experimental results showed that increasing table speed or head load increased the ...

Acrylic glass plates - HEKO

Traduire cette page

High-quality optical elements (lenses, mirrors, prisms) are made from acrylic glass through casting and mechanical processing (turning, grinding). Acrylic glass (PMMA) has no harmful effect on human organism. PMMA has many bio-medical applications due to its low immune response in vivo. This, almost anecdote-like, biocompatibility of PMMA with human body was confirmed during the Second World ...

Bone cements have been used very successfully to anchor artificial joints (hip joints, knee joints, shoulder and elbow joints) for more than half a century.Artificial joints (referred to as prostheses) are anchored with bone cement. The bone cement fills the free space between the prosthesis and the bone and plays the important role of an elastic zone.

In addition, the CPM-PMMA had higher flexural properties than the orthoplast samples. CONCLUSIONS: Although the CPM-PMMA powder presented a compromised particle morphology and narrow particle size distribution, when mixed with orthocryl liquid, the cured resin produced acceptable mechanical properties due to the large amount of cross-linking agent.
