  DP-Poly is a highly purified form of natural rubber (NR) from which most of the proteins and ash have been removed. The polymer is produced under very closely defined and
controlled conditions and contains c.a 96% rubber hydrocarbon compared to c.a 93% for normal natural rubber gradas. The removal of these materials confers special attributes to DP-Poly which enhances its value in certain specialised application.
 
  There ara basically two types of DP-Poly, made solely from high quality natural rubber latex.

DP-Poly (CV) : Viscosity stabilised type where the initial mooney is stabilised at between 60-70 mooney units.

DP-Poly (S) : Standard grade which does not have viscosity stabilisation feature. The initial viscosity is round 75-85 mooney units but because of the reduction in the non-rubber content, the rate of viscosity increases due to stieage hardening, typical of any natural, is relatively low.

 The main characteristics are :
Vary low protein content
Low volatile matter
Light colour
Very low dirt and ash content
Free from nitosamines
Free from malodour
 The aboveraw raw rubber characteristics are reflected in the following valuable attributes of
 DP-Poly vulcanisate :
Lower rate of creep and stress relaxation than normal natural rubber, especially in soluble EV-system
Lower water absorption-low volume swell
Transparent vulcanisates
Low chemical reactivity
Insensitivity to adventitious and absorbed water resulting in greater consistency in cure behavior and
  vulcanised modulus under conditions of variable humidity
 
Engineering applications such as seals, bearings, joint rings, hydro-mounts, building mounts, anti-
  vibration parts, shock absorbers.
Low Water Absorption
  Electrical insulation, sluice gate and marine rubber parts, pump stators, tank linings, oil-rig rubber parts etc.
Low protein/Low Antigen Content
  Medical healthcare and pharmaceutical applications such as adhesives, baby diapers, teats, dummies, garments, syringes, stoppers etc.
Low Dirt/Light Colour
  Moulded and extruded clean products such as tubings, hoses, toys, etc.
 
 The technology and know-how in the production of DP-Poly is covered under the UK Patent 8427736.
