Shenhua Printing Plate Knife Pad: Long-term continuous production anti-UV and anti-aging long-lasting solution

The production line operates continuously for 24 hours without interruption, with ample natural lighting and close proximity to windows and lighting for long-term exposure. The shock pads will be constantly subjected to the combined effects of light, oxygen, and heat. Regular shock pads are prone to surface cracking, hardening and brittleness, elastic degradation, and yellowing of color, resulting in decreased cutting accuracy in the middle and later stages and edge debris falling off. Deephua Printing Materials has developed long-lasting shock pads resistant to light and oxygen aging to extend the continuous service life and reduce the need for material replacement and downtime.

The material formula includes composite light stabilizers, antioxidants, and ultraviolet absorbers to form molecular-level protection, inhibiting the breakage of rubber chains caused by light and heat oxygen, delaying hardening, yellowing, and cracking; the base material uses weather-resistant synthetic rubber and elastomers mixed together, maintaining high mechanical performance after long-term exposure to light and heat, with an elastic attenuation rate controlled within 5% after continuous use for more than 30 days, far superior to regular shock pads. Anti-UV protective coatings can be added to the surface to further prevent damage to the internal gel by light.

The structure uses high tear-resistant and anti-frosting base materials, which do not shed debris or powderize over time and do not contaminate packaging products and the workshop environment; combined with a high fatigue-resistant formula, it is suitable for three-shift continuous cutting, with stable compression rebound performance, and does not require premature replacement due to aging. After being applied to a 24-hour production line of a large packaging printing enterprise, the continuous service period of the shock pads was extended from 7 days to 28 days. The defective rate caused by aging cracking and debris falling off was reduced to below 0.2%, and the annual downtime and material replacement time for a single production line was reduced by 70%, with significant reductions in overall material costs and downtime costs.
