โฆ Synopsis
A ceramic suspension incorporating fine sinterable silicon carbide powder in a polycarbosilane vehicle has been modified by additions of paraffin wax to make it suitable for plastic forming operations. The diluent enables higher volume fractions of ceramic to be incorporated and lowers the softening point of the suspension. The danger of temperature-induced crosslinking in processing machinery is alleviated.

The use of recycled polymers is widespread for the injection moulding of many commodity plastic parts. Recycled polymers are usually blended with virgin polymers to obtain the best trade-off between cost and low melt viscosity. This last constraint is necessary to avoid short shots and to minimize t
