Luterra Advanced Materials recently announced that its two core cylinder release agent products-Water Cylinder Release Agent (PR-07) and Mineral Oil Release Agent (PR-08)-have achieved significant results in production applications across multiple tissue mills in Southeast Asia and China. Targeting common pain points faced by high-speed paper machines producing tissue, facial tissue, and other lightweight papers-such as Yankee dryer sticking, dusting, and sheet breaks-these two products, with their differentiated technical approaches, have successfully helped customers reduce downtime, improve paper surface quality, and extend doctor blade service life.
Customer Challenge: Persistent "Sticking" and "Paper Defect" Issues on High-Speed Machines
During the production of tissue and printing/writing papers, residual ink, resins, stickies, and cationic starch added for strength tend to form deposits on the high-temperature Yankee dryer surface, leading to sticking and cylinder buildup. This not only causes sheet breaks and surface defects such as oil spots or pinholes but also accelerates dryer doctor blade wear, severely constraining production efficiency and yield.
Solution: Dual Product Line Precisely Matched to Different Process Needs
Luterra Advanced Materials offers two release agent products based on different chemical principles, enabling customers to select the optimal match based on their grade positioning and cost structure.
1. Water Cylinder Release Agent (PR-07): The Clean Choice for Premium Grades
PR-07 is a new-generation water-based release agent synthesized from premium organosiliconematerials. Its core technical value includes:
Clean Release, No Oil Stain Risk: This non-ionic, milky white liquid is readily dispersible in cold water. It forms a high-temperature-resistant lubricating film on the dryer surface, delivering triple effects of lubrication, release, and gloss enhancement. The water-based formulation fundamentally avoids oil stain issues associated with traditional oily products, making it particularly suitable for premium tissue, facial tissue, food wrapping paper, and other grades with stringent surface cleanliness requirements.
Strong Process Adaptability: Technical specifications indicate a solid content of 20% ± 2% and pH range of 6.0–9.0, ensuring stability across wide pH ranges and high-temperature conditions. Recommended dosage is 0.3–1.0 kg per metric ton of dry pulp, applicable via spray method(diluted and sprayed onto the dryer) or pulp addition.
2. Mineral Oil Release Agent (PR-08): The Cost-Effective Choice
PR-08 is a high-performance release agent formulated with mineral oil, fatty acid esters, and various imported raw materials. Its competitive edge lies in:
Strong Release and Equipment Protection: This product is an oil-based liquid (available from colorless to amber) with 100% active ingredient content. It forms a highly effective lubricating layer between the dryer and doctor blades, significantly reducing sheet breaks, linting, and dusting, while substantially extending doctor blade service life.
High Cost-Effectiveness and Versatility: Due to its high active content, the recommended dosage is only 0.2–1.0 kg per ton of paper. Customer feedback confirms its cost-performance advantage over similar imported products, making it suitable for a wide range of paper grades including writing paper, duplex paper, corrugating medium, and fruit wrap paper.
Customer Value: Comprehensive Benefits
On-site application data confirms that customers adopting the Luterra Advanced Materials release agent program have achieved the following key benefits:
Improved Operational Stability: Effective resolution of sticking issues leads to reduced sheet break frequency and minimized unscheduled downtime.
Enhanced Product Quality: Improved paper smoothness and gloss, with paper surfaces free from oil spots and pinholes, significantly increasing the finished product yield.
Optimized Overall Costs: While enabling higher machine speeds, the program effectively controls per-ton chemical costs thanks to low dosage requirements and also extends the replacement cycle of doctor blades and other consumables.
Beyond high-quality release agent products, Luterra Advanced Materials can also customize Yankee dryer spray equipment and provide professional installation and commissioning guidancebased on customer requirements, offering one-stop service from chemical supply to application process support.
