Pads and rollers for the printing industry
Besides mold-making, Silicone RTVs are extensively used for printing over plastic and metal surfaces. A wide range of rollers and pads can be made in a variety of hardnesses based on the shape and size of the object to be printed on. Ideally the printing pad or roller should last as long as possible so as to not disrupt the flow of the production process.
Our materials help achieve this due to their superior properties, such as:
Flexibility and high tear strength
Complicated object shapes require the pad to bend or stretch over the surface sufficiently so as to not distort the print job. We have RTVs with a flexibility upto 550% in order to fulfill every print job.
Pads tend to be static in nature due to constant contact with plastic surfaces. This tends to attract dust and other particulate matter to the pad surface which is undesirable as it affects print quality. We have antistatic materials which prevent this from happening.
Good ink transfer
The rubber needs to have the property to pick up ink from the ink cup and transfer it to the substrate completely without any residue. Pads that leech oil are undesirable and affect ink transfer. Our pad materials have a low oil content, eliminating this issue.
Due to the low oil content in our RTV, it gives a user the option of adding oil to modulate the hardness without the oil leeching to the surface while printing. Fortisil also has multiple grades in different hardnesses to avoid the need for adding oil, thus increasing pad life.
Our materials usually cure within 2 hours, thus allowing for faster production of pads.
High Print Output
Due to the presence of good fillers, pads from our RTVs are known to give 700,000 to 1 million prints per job.
