PAPER INDUSTRY

Introduction:

An extensive range of rubber covered rolls are used throughout the paper making process.  These rolls are primarily used in the de-watering, sizing, drying and calendaring processes, requiring a range of rubber compounds to provide chemical, temperature, abrasion & co-efficient of friction resistance properties along with hardness stability, dynamic properties, heat stability & low co-efficient of thermal expansion characteristics.

Press Section:

MARROCK (0-2 P & J)

• Can be used for hard press rolls

MARROCK II (0-2 P & J)

• Can be used for hard press rolls

MARPRESS I (12-45 P & J)

• For Press rolls and Suction Press rolls
• Temperatures, up to 140C
• Good chemical resistance, resistant to bleaching agents

MARPRESS II (12-45 P & J)

• For Press rolls and Suction Press rolls
• Temperatures, up to 120C
• Good abrasion & chemical resistance for moderate loads

MARPRESS III

• For Press rolls and Suction Press rolls
• Temperatures, up to 150C
• Excellent heat and chemical resistance combined with excellent abrasion resistance

Wet End Applications

Wire/Felt Guide Rolls

• MARROCK (0-2 P & J)
• Excellent abrasion resistance, low hysteresis and superior chemical resistance; the hardness stability enables is to outperform typical ebonite compounds even at higher operating temperature

Couch Rolls

• MARCOUCH I(30 – 40 P & J)
• Specially formulated for softer roll positions with excellent abrasion resistance, low hysteresis and superior chemical

Lumpbreaker

• MARBRAKE I (150 – 200 P & J)

• MARBRAKE II (150 – 200 P & J)
• Good resilience, non-stick and self-cleaning properties

Wet Lap Rollers

• MARLAP (8 – 10 P & J)

Breast Rollers

• MARBRUST I (5 – 99 P & J)
• Temperature Resistance 275C
• Excellent abrasion resistance, low hysteresis & superior chemical resistance enables them to outperform typical Nitrile compounds

• MARBRUST II (5 – 15 P & J)
• Temperature Resistance 325C
• Superior abrasion resistance, low hysteresis & superior chemical resistance; the compounds outstanding heat and chemical resistance allows it to outperform typical hard rubber compounds especially at higher operating temperatures.

Coating Rolls

MARCOATE I (15 – 90 P & J)

• Suitable for roller or blade applications
• Good all-round properties

      MARCOAT II(15 – 90 P & J)

• To be used where traces of bleaching agents are likely to be present
• Excellent abrasion and chemical resistance
• Used for roller and blade applications

      MARCOAT III (15 – 90 P & J)

• Outstanding mechanical and chemical properties
• Outstanding abrasion properties
• Used for roller and blade applications and other costing systems such as Symsizers
