BALL PEN INKS

GENERAL INFORMATION ON BALL PEN INKS

Our Ball Pen Inks under normal condition are compatible with refill tubes made of polyethylene, polypropylene, brass stainless steel and tips made of brass, brass nickel plated, nickel silver, stainless steel, german silver with stainless steel or tungsten carbide balls.

In order to get the optimum performance results we request our customers to supply us a certain quantity of tips, tubes, & unassembled pen bodies; before recommending best suitability of Inks.

Our inks have rubber elastic properties. The rubber effect avoids accumulation of ink around the tip lips.

The intensity of ball pen writing is controlled by

Dye content
Lay - down

2a. Ink viscosity
2b. Tip construction
2c. Ball size & ball surface

So even a best quality ink will write pale if lay - down is low & cheap Ink will write intense if lay - down is high.

Ink Handling, Tip Selection & Shelf Life.

In Ink filling machine, the filling station should be cleaned carefully, every time Ink is changed to avoid contamination of the Inks, otherwise if may lead to mismatch of a required refill colour & even defective refill.
All Ball pen inks should be stored in temp., range of 0 °C to 30 °C to avoid reduction in shelf life of bulk Inks.
We check all Inks in standard tip lot, but it is advisable to carry out pilot studies of tip & ink for required Ink lay down.
We check static leakage test in standard tip / tips supplied by customer, under laboratory conditions but we advice pilot study for static leakage when tips lot is changed.
Shelf life

All the shelf life tests are done with standard tips at our laboratory. (For any specific test we can do testing in customers standard tips : Testing time is 14 weeks.)

This technical information is based on our actual state of knowledge. A guarantee for certain characteristics or suitability for special application can not be deduced from this. It does not release the user of our products from his own tests and examinations. The storage, handling and application of our products take place in responsibility of our customers in accordance with the local and legal regulations.
