ODOUR IS BLOWN FVC BOTTLSS
OB.nCT;
Tc assess the effect of stabiliser +ype on the odour nr blown FVC bottles.
CCHCIUSIORSt
1. Stanclere 176 caused most residual odour in P7C bottles. 2. llellite 625 caused least residual odour in FVC bottles. 5. Stanclere 80 and Mellite 825 stabilised bottles were
discoloured orange. 4. Stanclere 176 anl llellite 8 51 stabilised bottles had good colour. 5- Addition of c* phenyl indole to Stanclere 90 gave aone improvement
ir. bottle colour.
IIJTRODPCTIOK:
At a re^j.t trial r,r; a Lesieur DS15 blow moulder at Kingston Moullings, attention was drawn to the excessive fuming and objectionable smell of tne bottles. Work has been done to rwduce the level of odour, oy stabiliser variations.
