Application of High-Quality Vulkollan Polyurethane Printing Rollers

In the printing industry, precision, durability, and surface performance are key factors that determine the efficiency and quality of the production process. The Vulkollan polyurethane printing roller stands out as a premium solution, offering exceptional mechanical and chemical performance. Widely adopted in flexographic, gravure, and offset printing systems, Vulkollan rollers deliver a unique blend of resilience and accuracy, making them an ideal choice for high-end printing applications.

What is Vulkollan?

Vulkollan is a high-performance elastomer made from a specific formulation of polyurethane (desmodur 15 and polyols). It is known for its outstanding combination of:

• High mechanical strength

• Excellent tear and abrasion resistance

• Superior dynamic load-bearing capacity

• Chemical and oil resistance

These properties make vulkollan a premium material for demanding industrial applications, especially where conventional rubber or lower-grade polyurethane fail.

Key features of Vulkollan printing rollers

• Superior surface hardness & elasticity

Vulkollan rollers provide a uniform hardness range from 65–95 shore A, ensuring optimal ink transfer and even pressure distribution on various substrates.

• High resistance to wear and tear

The rollers exhibit exceptional resistance to abrasion, ensuring a long service life even under continuous high-speed operation and harsh solvents used in printing.

• Excellent rebound and compression set

These properties reduce deformation and ensure consistent performance, especially in high-cycle printing environments.

• Stable performance across temperatures

Vulkollan rollers maintain flexibility and durability across a wide temperature range, from -20°c to +80°c, making them suitable for diverse printing environments.

• Precision machinability

The material can be precisely ground and machined to tight tolerances, ensuring high dimensional accuracy crucial for fine printing results.

Applications in the printing industry

Vulkollan printing rollers are used in various printing systems, including:

• Flexographic printing machines

Where consistent ink metering and pressure are crucial for high-speed packaging prints.

• Gravure printing systems

Offering durability and solvent resistance for large-volume printing of films, foils, and labels.

• Offset printing presses

Providing stable performance for paper and board printing with minimal roller swelling.

• Digital and industrial printing equipment

Supporting precision movement and high-resolution printing applications.

The high quality Vulkollan polyurethane printing roller is engineered for demanding industrial environments where reliability and precision are non-negotiable. With its outstanding physical properties, long service life, and adaptability to various printing techniques, vulkollan rollers offer a significant advantage to manufacturers seeking consistent print quality, reduced downtime, and optimized production efficiency.

Whether for flexible packaging, labels, or high-volume publications, investing in vulkollan printing rollers ensures that your printing process stays ahead of the curve in both quality and performance.
