Tosaf's Extrusion Coating White Masterbatches for High-temperature Processes

Tosaf offers white MBs for different extrusion coating processes and applications.

• ME800047 – The PE-based white MB is the ideal option.
• MP800502 – Designed especially for outdoor protective PP films.
• VE800497 – A special combination white MB with UV stabilizer which offers superior quality in HDPE and PP tarpaulin production process.

Increased Heat Stability and Environmental Benefits

Extrusion coating white masterbatch offers superior heat stability. They significantly reduce both smoke and odor during high-temperature processing. This is a common challenge in extrusion coatings.

This advanced formulation addresses more sustainable and cleaner production processes. Its low-emission profile improves workplace safety and aligns with tightening environmental regulations worldwide.

Enhanced Production Efficiency

In addition to its environmental advantages, Tosaf's extrusion coating white masterbatches contribute to higher production efficiency compared to traditional alternatives. Its formulation ensures better process control, reducing downtime, and waste. These are the key factors for manufacturers aiming to optimize production in this competitive market.

Meeting the Challenges of Extrusion Coating

Extrusion coating remains one of the most demanding processes. It requires the application of a thin polymer layer to a substrate at processing temperatures close to the thermal degradation point of the polymer (approximately 300°C). Traditional challenges continue to be critical issues for manufacturers, including:

• necking,
• heavy smoke,
• strong odor,
• poor dispersion,
• gel formation, and
• die buildup

The white MBs were developed to overcome these extrusion coating challenges. With its exceptional heat resistance, the masterbatch maintains high dispersion quality even under extreme conditions. This results in a homogenous coating with fewer filter changes and significantly reduced gel formation. This further contributes to smoother, more consistent production.

Opportunities for Cost Savings

Tosaf's white MBs have high opacity. Hence, manufacturers can achieve the same visual effect with lower addition levels, even in very thin layers. This efficiency not only enhances production speeds but also reduces material costs. This makes it an attractive option for companies focused on profitability.

Corona Retention and Printability

The white MBs do not contain migrating additives. They ensure high corona retention and excellent printability. These are the two critical factors in the production of high-quality coated products. Moreover, reduced die buildup contributes to longer production runs. This in turn minimizes maintenance and further enhances overall efficiency.

Tosaf is committed to understanding your needs and delivering masterbatches that exceed industry standards. They ensure sustainable growth and innovation in extrusion coating processes worldwide.
