HC5100 Aliphatic Hydrocarbon Resin C5（Rubber Grade）

HC5100 is a light-colored C5 hydrocarbon resin with a softening point around 100 °C; it exhibits excellent compatibility with NR, SBR and BR. Adding 3–8 phr during rubber compounding markedly improves tack, green strength and elongation without affecting cure rate, making it a highly efficient, eco-friendly tackifier for tires, shoe soles and conveyor belts.
