Mode of action
H654, with its reduced solubility, migrates to the surface of the vulcan izates 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 vulcan izate 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
20kg/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.
FAQ
Q: What is the main difference between H654 and H3241?
A: H654 has a higher melting point and provides more durable protection, suitable for high-temperature processing and long-term outdoor use. H3241, on the other hand, focuses more on general-purpose regular protection.
Q: For which scenarios are they applicable?
A: Outdoor rubber products, high-temperature processing tires, heavy-duty conveyor belts, outdoor seals, etc., which require long-term anti-aging protection.
Q: What are the storage and usage precautions?
A: Store in a sealed manner in a cool and dry place, away from high temperatures; the addition amount is generally 2%-4%, and can be adjusted according to the usage scenario of the product.
