Blowing Agents, OBSH & Microspheres
Blowing agents are substances which produce a cellular structure through a foaming process in many materials (i.e. polymers, plastics and metals) which undergo hardening or phase transition. Microspheres are small spherical particles which are available in a variety of materials such as glass, ceramics, polymers and metals. These are generally used in the preparation of biodegradable polymers.
