Type RE for Wet Application

Rubber Quality

MH 300

Physical Properties
Temperature Hardness Wear resistance Elasticity Tear resistance pH-range Colour	: 95-110°C   (120°C max) : 70+/- 5 ShA : good : good : good : 3 - 9 : blue

MH 300 may be applied to spreader rolls as a standard cover quality in a number of positions in the machine.

Resistance

Excellent resistance against all types of oil, grease, kerosene, and petrol. Good resistance against most chemicals, acids, alcohol and corroding agents in moderate concentration.

MH 300 is not resistant against ozone, ketone, ester or hydrocarbons.

Applications

Standard quality for paper machines, size presses, slitter winders and re-winders.

Options

• HR (high release) additive in order to improve release properties.
• MH 300 black with improved wear resistance.
• Grooving to prevent "air-floating" at high web speeds.
• 1 or 2 wire layers according to speed range.

MH 211

Physical Properties
Temperature Hardness Wear resistance Elasticity Tear resistance pH-range Colour	: 95-110°C   (120°C max) : 85 +/- 5 ShA : very good : good : good : 2,5 - 11 : black

MH 211 is more dense in structure and therefore more wear resistant than our standard quality MH 300. Due to its higher water resistance it is well suited to wet application in all kinds of machines.

Resistance

Excellent resistance against all kinds of oil, grease, kerosene and petrol. Good resistance against most chemicals, acids, alcohol and corroding agents in moderate concentrations.

MH 211 is not resistant against ozone and all kinds of ketone, ester and hydrocarbon.

Applications

Due to its special waterproof property, this compound is highly suitable for wet service installation in wires and felts. This cover quality has also proved itself in the steel and aluminum industry.

Options

• MH 211 XL with improved wear resistance and release property.
• Wire reinforcement according to speed range.
• Steel or stainless steel end tubes.

MH 201

Physical Properties
Temperature Hardness Wear resistance Elasticity Tear resistance pH-range Colour	: 95-110°C   (120°C max) : 65 +/- 5 ShA : very good : very good : very good : 3 - 9 : beige

MH 201 is an especially wear resistant compound for application mainly in dry positions with abrasive media.

Resistance

Excellent resistance against all kinds of oil, grease, kerosene and petrol. Good resistance against most chemicals, acids, alcohol and corroding agents in moderate concentrations.

MH 201 is not resistant against ozone ketone, ester or hydrocarbon.

Applications

Due to its extremely high wear resistance, good results are being obtained in dry applications on slitter winders.

Options

• Grooving to prevent "airfloating" at high web speeds.
• 1 or 2 wire layers as reinforcement according to speed range.

TEMPWEAR

Physical Properties
Temperature Hardness Wear resistance Elasticity Tear resistance pH-range Colour	: 180°C-200°C max : 70 +/- 5 ShA : excellent : good : very good : 3 - 9 : brown

TEMPWEAR is a specially designed sleeve for high temperatures, with very high wear resistance.

Resistance

Excellent resistance against all kinds of oil, grease, kerosene and petrol. Good resistance against most chemicals, acids, alcohol and corroding agents in moderate concentrations.

TEMPWEAR is not resistant against ozone, ketone, ester or hydrocarbon.

Applications

Due to its special resistance against high temperatures, this compound is suitable for application in extremely high temperatures, for instance, near infrared or in dryer parts of paper machines.

Its extreme wear resistance makes it an excellent choice for application with abrasive media such as slitter winders.

Options

• HR (high release) additive in order to improve release properties.
• Grooving to prevent "airfloating" at high web speeds.
• 1 or 2 wire layers as reinforcement according to speed range.

BECALON

Physical Properties
Temperature Hardness Wear resistance Elasticity Tear resistance pH-range Colour	: 120°C-140°C max : 65 +/- 5 ShA : good : good : good : 2 - 12 : light blue

BECALON is our special quality for size press application because of its excellent release properties.

Resistance

Excellent resistance against most chemicals, acids, ozone, oil, grease, petrol and solvents in moderate concentrations.

BECALON is not resistant against ketone, ester, heavy oxidizing acids or chlorinated aromatic and aliphatic hydrocarbons.

Applications

Due to its excellent high release properties, this compound is applied, with very good results, in size presses, coaters and foil processing industries.

Options

• BECALON 200 HR (high release) as an alternative to PTFE sleeves.
• Wire reinforcement according to speed range.
