Trade name: Tarnoform® 
Chemical name: acetal copolymer 

Unit: Grupa Azoty S.A.

Product description 

Tarnoform® is the trade name of acetal copolymer, a high quality engineering thermoplastic resin produced by cationic polymerisation of trioxane used in manufacturing of products by injection moulding and extrusion.

Main product properties
  • negligible change of impact strength at temperatures between - 400C and 1100C, 
  • high stiffness and mechanical strength, 
  • high fatigue endurance, 
  • lack of influence of air humidity on mechanical properties, 
  • excellent dimensional stability, 
  • resistance to most organic solvents, bases and acids of pH > 4, 
  • high hardness and abrasion resistance, 
  • low friction coefficient in connections involving typical materials, 
  • high resistance to warping, even at high temperatures, 
  • outstanding electrical and dielectric properties, virtually unaffected by changes of ambient temperature and humidity,
  • high resistance to water, bacteria, fungi and insects (for applications requiring resistance to prolonged exposure).

Applications and uses

  • for production of semi-finished goods, like: plates, sheets, pipes,
  • gear-wheels, gears, plain and roll-bearings,
  • zips, snap-fits and buckles,
  • lighter housings,
  • vertical blind parts,
  • electric switch sliders,
  • automotive industry (cable fixtures, fuel system elements, window motion systems, electric switch sliders, impellers and casings of car blowers, door handles, switch levers, mirror housings and fixtures, speaker grills), 
  • hydraulic and pneumatic fittings (pipe connectors, valves, taps, bodies and impellers of pumps for corrosive media and sewage), 
  • potable water pipeline elements (valves, couplings),
  • medical instrument parts,
  • conveyor belt elements.

Packing and transport

Tarnoform® may be packed into:
  • ALU/PE welded bags, with the net weight of 25 kg, which are formed on pallets with weight up to 1000 kg and wrapped with stretch foil, 
  • into octabins with net mass up to 1000 kg , 
  • other kind of packaging agreed with customer.

Loading units on pallets are wrapped in stretch foil. Changes in packaging and marking is allowed if agreed with customer.

Tarnoform® should be transported in covered means of transport 
Transport conditions should protect the bags from damage, moisture and impurities. The piling of pallets is not allowed. 

Tarnoform® is not a hazardous product according to ADR, RID and IMDG regulations. 


Tarnoform® should be stored in closed original packaging of the producer acc. to pt. 3 in dry rooms with temperature 10-30 0C, and at least 1 m away from heating devices. 
The bags with granulate should be transferred from the cold storage room into the warm workshop about 24 hrs before the material is to be used, to balance the temperatures and prevent moisture condensation.
