Firstly, the sealing industry faces pressure to innovate and adopt environmentally friendly practices to align with China's carbon reduction targets. This pressure catalyzes research and development efforts towards eco-friendly materials, energy-efficient production processes, and sustainable manufacturing practices. Investments in research aimed at reducing the carbon footprint of sealing products are likely to increase as China pushes for greener industries.

- Quality Standards Opt for oil seal kits that meet industry standards and specifications. High-quality seals are essential for ensuring the reliability of the hydraulic system.

Maintenance protocols should include regular checks during equipment servicing, especially in high-demand applications. Operators should monitor lubricant levels, look for any signs of leakage, and ensure that seals remain free from debris that could compromise their effectiveness.

The majority of the available studies have been performed in rats, just few of them in rabbits and dogs. Among those meeting the current criteria for toxicological testing, the no observed adverse effect level (NOAEL) values for the different modified celluloses were identified most often corresponding to the highest tested level or changes in body or organ weights. For microcrystalline cellulose (E 460) the identified NOAELs in rats ranged from 3,769 mg/kg body weight (bw) per day to 9,000 mg/kg bw per day and in all cases corresponded to the highest levels of the test substance. For methyl cellulose (E 461), the dose level of 3% in rats (equivalent to 2,700 mg/kw bw per day) was selected as the NOAEL based on a decrease in body and organ weight displayed in male rats administered with the top additive level (10%, equivalent to 9,000 mg/kg bw per day and day).
