C5 petroleum resin's characteristics and application fields are as follows:
Characteristics:
Chemical Structure: Derived from C5 fractions abundant in hydrocarbons with 5 carbon atoms, such as isoprene and piperylene, C5 resins are classified as aliphatic or alicyclic resins, devoid of aromatic structures.
Physical Properties:
- Low to medium molecular weight, typically ranging between 1,000 and 3,000, categorizing them as low molecular weight thermoplastic resins.
- Color varies from yellow to light brown, demonstrating good clarity.
- Softening points fall within the range of 80 to 160°C, signifying moderate hardness and favorable melt-processing properties.
- High solubility in solvents like benzene, toluene, xylene, and compatible with various polymers including EVA and polyethylene.
Properties: C5 resins are characterized by low odor, low volatility, strong adhesive properties, heat resistance, stability, water resistance, alkali-acid resistance, and a relatively low environmental impact.
Environmental Friendliness: Compared to some traditional resins, C5 resins offer reduced environmental impact during production and use.
Application Fields:
Adhesives: Employed as tackifiers in hot-melt adhesives, pressure-sensitive adhesives, construction adhesives, automotive component assembly, tire manufacturing, woodworking, packaging materials, bookbinding, personal hygiene products, and footwear, enhancing bonding strength and weather resistance.
Coatings and Inks: Added to improve coating flow, adhesion, weatherability, and chemical resistance, and to boost ink viscosity, gloss, and printability.
Sealants: Enhances sealing properties in sealant formulations used in construction, automotive, and electronics for leak prevention and surface protection.
Modifying Agent: Blended with rubber (e.g., natural rubber, styrene-butadiene rubber SBR, polybutadiene) to reinforce physical properties and processing capabilities.
Road Marking Paints: Used in thermoplastic road marking paints for excellent adhesion, wear resistance, and clear visibility.
In conclusion, C5 petroleum resin, with its distinct characteristics, finds broad application and potential across sectors such as adhesives, coatings, inks, sealants, and as a modifier, highlighting its versatility and value in various industries.
