DELRIN (POM) BALLS


Very light homopolimeric thermoplastic resin balls, they provide good mechanical characteristics, corrosion resistance, wear and abrasion resistance.

They are even good electric insulators and auto lubricant materials.

 

Applications

Spray agitators, light safety valves, low load bearings. Special pumps and valves, sliding rails for furniture, fluids flow check devices, medical instruments.

They are used in foodstuff, chemical, electronic, pharmaceutical industry.

Corrosion Resistance

Delrin is resisting in contact with basic, neutral and average acid compounds, sea water, petroleum products, mineral oils and greases, inorganic salt solutions, aliphatic, aromatic and chlorine hydrocarbons, low gradation alcools, ether. It's not resisting in contact with strong acids (hydrochloric, phosphoric, nitric and sulphuric), mineral acids, chlorides, alkalis.
