Low temperature performance
Test pieces cut from a dip moulding produced under normal conditions
were tested generally in accordance with BS 2782:1/104A (cold bend
test). Samples from 100 BS softness mouldings passed the test at -50°C
whilst those from 45 BS softness mouldings passed at -20°C.
Additives can be incorporated in all our plastisols, except food grades,
to improve their resistance to flame. The specialised grades listed
above include PDM 100 FR spec. UL.94-VO which has been tested positive
by the American Underwriters Laboratories Inc. who have issued the
coveted QMFZ2 yellow-card approval certification to Plastic Mouldings
and we believe we are the only dip moulding company in Europe to achieve
Gaiters and bellows are often produced by dip moulding and in order
to investigate the fatigue strength of such items a typical moulding
was fitted to a rig in which it performed more than one million reversals
without visible signs of fatigue. The amplitude of the reversals was
100mm and the frequency 115 per minute.
Most of our plastisols are classed as non toxic. It is not possible
to list the complete range of materials that can be manufactured,
please consult us for further information.
