R-50D is a high-activity resorcinol-phenol-formaldehyde resin that combines the advantages of phenolic and resorcinol-formaldehyde resins. Compared to phenolic resins, the resin has a lower curing temperature and a shorter curing time. At the same time, it has excellent water and weather resistance and high bonding strength. The low content of free resorcinol can avoid problems such as the operating environment, the operator's health, and the "spraying" phenomenon of resorcinol on the surface of the rubber compound due to high temperature sublimation during the mixing process.

Product advantages
The reinforcing effect is direct. A small amount of addition can significantly improve the hardness, rigidity and wear resistance of the rubber, reducing the wear and cracking of the products; the fluidity is moderate, the mixing and dispersion are fast, and there will be no agglomeration or clumping; the heat resistance is good, the size remains stable after vulcanization, and it is not prone to deformation due to heat; it does not flake or migrate, and does not affect the appearance of the rubber surface; it is suitable for tires, industrial rubber rollers, conveyor belts, and wear-resistant seals. The processing is simple and the cost performance is outstanding.
Precautions
This product is a liquid resin that prevents splashing;
Please wear related protective equipment during use to avoid direct contact with the skin.
Packaging
It is 200kg plastic barrel packaging or 1 tons of barrel packaging.
Storage
It should be stored in a cool, dry, ventilated place, beware of broken barrels, and should be used immediately after damage.
It can store up to 3 months at 15°C.
FAQ
Q: What are the differences between R-50D and previous models like 3102?
A: It is a thermoplastic resin, specifically used for reinforcing rubber, and does not require long-term high-temperature curing. It is more suitable for the rubber vulcanization system.
Q: What is the normal addition amount?
A: Generally 5-15 parts, adjusted according to the hardness requirements of the rubber.
Q: What are the storage requirements?
A: Store it sealed in a cool and dry place, away from heat sources, to prevent softening and adhesion.
