Actmix Pre-dispersed EPDM-bound Rubber Retarder CTP-80 PVI-80
Cyclohexylthiophthalimide: C14H1502SN
M.W.: 261.34
CAS: 17796-82-6
EINECS: 241-774-1
Properties
Activeingredient CTPi avulcanization retarderof nature rubber and diene rubbers, which can unnoticeably prolong total vulcanizing time. It can improve processing safety and not impact properties of vulcanizates combination with sulfenamides or thiazoles. This product can ignificantly improve the storage stability and high temperature processing safety performance ofunvulcanized rubber, fullyimprove equip-ments production capacity. It does not cause a contact stain.
Dosage
Usually 0.2-2.0phr, will be blooming if more than 5.0phr.
Applications
Nature and synthetic rubber compounds(tyre,conveyor belt,shoe soles,molded and extruded products).
Advantages
All the raw materials with a particle size of 150 µm are thoroughly sieved. After being processed into mother rubber particles, no dust will befly upwarded.
This avoids the unpleasant smell emitted by CTP and protects the health of the operators.
The mother rubber particles CTP-80 are effectively pre-dispersed using rubber carriers, ensuring the activity of CTP.
The mother rubber particles do not stick together at room temperature, making the ingredient mixing convenient and accurate.
At a lower temperature such as 50°C, it has a lower Mooney viscosity, improving the dispersion quality of CTP in the rubber compound.
During granulation, the mother rubber particles are filtered simultaneously, without impurities.
When making extruded products, it will not cause the filter screen to get clogged, reducing the waste rate and improving production efficiency.
It has excellent compatibility with different rubbers.
FAQ
Q: What is the main function of CTP-80?
A: Its core function is to prevent scorching and premature vulcanization of the rubber during processing, thus avoiding its premature destruction.
Q: How much is generally added?
A: The conventional dosage is 0.1 - 0.3 parts, which can be adjusted slightly according to the thickness of the rubber compound and the processing temperature.
Q: What should be noted when storing?
A: Store it in a sealed, cool place, avoiding high temperatures, moisture, and preventing the particles from sticking together.
