Introduction

C5 Hydrocarbon Resin is a low-molecular-weight thermoplastic resin derived from the polymerization of C5 fraction, primarily consisting of aliphatic dienes and olefins from petroleum cracking. It appears as light-yellow to amber granules and is widely used as a tackifier due to its excellent compatibility with natural and synthetic rubbers, EVA, SIS, and other polymers. This resin is especially valued for its ability to enhance adhesion, cohesion, and processability in road marking paints, hot-melt adhesives, pressure-sensitive adhesives, coatings, and inks.

With a softening point range between 87°C and 165°C, C5 hydrocarbon resin provides optimal viscosity for road marking paints, ensuring quick drying and strong performance under various environmental conditions. However, for customers purchasing during summer months or those who plan to store the resin for extended periods, it’s important to consider that prolonged shipping times or long-term storage without use may lead to clumping. To prevent this, we recommend fast delivery and prompt usage of the resin to maintain its ideal quality and functionality.

Origin & Composition

C5 hydrocarbon resin is derived from the C5 fraction of petroleum cracking (mainly piperylene, isoprene, and other aliphatic olefins/dienes). It is a low-molecular-weight, non-polar thermoplastic resin.

Appearance

Typically light yellow to amber granules. Some grades (e.g., hydrogenated C5 resin) can be water-white.
Molecular Properties
Molecular weight: ~300–3000 g/mol (low-molecular-weight resin).
Non-reactive, stable structure.
Softening point usually between 80–120 °C (depending on grade).
Performance Characteristics
Good adhesion and tackifying performance.
Excellent compatibility with polymers like NR, SIS, SEBS, EVA, SBS, and PE.
Enhances tensile strength, hardness, brightness, and gloss of finished products.
Resistance to aging, UV, chemicals, and water.
