Function： 

Anti-check wax to protect rubber articles against caused by ozone and
weathering influences.

Product description ：Composition: Mixture of fully refined paraffine wax and microwax with                                                                medium wide MWD
                                      Appearance:  white to yellowish flakes
                                      Density, 20 °C: approx. 0,92 g/cm3
                                      Congealing point: 61 - 67°C
                                      Physiological properties: see safety data sheet

Use Mode of action:

H654, with its reduced solubility, migrates to the surface of the vulcanizates
and forms there a complete protective film which remains stable at
temperatures from -10°C to about 50 °C. The formation of the protective film
takes place at a medium-fast rate. The protective film shows an excellent
stability against dynamic stress. Antiozonants and antioxidants are carried to
the surface of the vulcanizate by the migration of Microwax H654.

Processing:

The flake form provides easier weighing and mixing. To ensure a good
dispersion it is recommended to add Microwax H654 right at the beginning of
the mixing cycle. The mixing temperature should exceed the melting point of
the anti-cacking wax.

Dosage:

for tyres 1 - 4 phr; in other rubber up to 10 phr depending on the type of
compound

Application:

Tyres, conveyor belts, cable coverings as well as technical moulded and extruded articles (profiles) which are used at higher service temperatures.
Microwax H654 meets test specifications at ozone chamber temperatures of
about 45 °C. The protection may be extended by means of blending with lower
melting Microwax grades.

Packing ：20 kg PE bags

Storage stability：

3 years, if stored at temperatures not exceeding 35°C; at higher temperatures
caking may occur. This, however, has no effect on the performance.
