Printing Rubber Roll

Black Zest

Application

Ink roll for sheet-feed printing process (for oil-based ink )

Characteristics

① Swelling and extracting is low against chemical effect of ink and cleaning agent, and can maintain the stable nip width for a long time.
② Rubber heat generation is low and keeping the nip width to be stable because it is very insignificant thermal expansion in the longtime running.
③ Mechanical strength is high so the damage of forming and transferring rollers will hardly occur. ( Cracking or abrasion occurs rarely )
④ Can use either aroma-free ink or soybean oil-based ink.

Hardness	２５，３０，３５
Color	Black

Ink resistant property

Experiment Method：Sink the test piece (25 x 25 x 2mm) in the soybean oil and measure at scheduled day.

Heat generation data

Experiment Method：Temperature indicates heat generated by our roller heat generation test machine.(Nip Width: 5mm / Roller Revolution: 3000rpm)
