Safety in injection techniques

The materials used in injection moulding processes come in a variety of forms:

• powdered state, for thermosetting resins such as phenoplasts (bakelite, formophenolic resin), for certain thermoplastics (polyvinyl chloride, for example) and for silicones;

• granules, for thermoplastics ;

• pasty state, for fiber-reinforced unsaturated polyester resins used in the BMC (Bulk Molding Compound) process.
