C5 aliphatic hydrocarbon resin for hot melt adhesives
C5 Hydrocarbon resin is playing gradually more and more important role as tackifier in the adhesive and sealant industry, especially in the application of hot melt adhesive and pressure sensitive adhesive. The series of petroleum resins product are a category of C5 aliphatic hydrocarbon resins applicable for hot melt adhesive and pressure sensitive adhesive. These products have an excellent compatibility with a wide variety of elastomers including natural rubber (NR), synthetic rubber, Ethylene Vinyl Acetate (EVA) and styrenic block copolymer such as SIS, SBS, SEBS, SEPS. Additionally, they also have a good compatibility with the natural tackfying resins such as terpene, rosin and thereof derivatives. At the same time, all the properties of adhesive can be improved in various degrees by the application of these C5 petroleum resins. In recent years, C5 petroleum resins are gradually replacing the natural resin tackfier(such as terpene and rosin) due to its advantages of high deep strength, fast tack, stable adhesion performance, moderate melting viscosity, high thermal resistance, good compatibility with polymer basis, economic price.
Good fluidity which can improve the wetting property of master material.
Excellent initial adhesion performance
Super aging resistance performance
Light color material
Transparent, little smell and low volatility material
Application field: hot melt adhesives, solvent base adhesives, adhesives, sealants, glue etc
C5/C9 copolymer resin is a kind of thermoplastic resin produced by pretreatment, polymerization, distillation and other processes of C5 and C9 fractions produced by petroleum cracking. It is not a high polymer, but a low molecular weight between 300-3000. Polymer. It has the advantages of C5 petroleum resin and C9 petroleum resin. It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance. It is chemically stable to acid and alkali, and has the characteristics of good viscosity adjustment and thermal stability. Since the structure does not contain polar groups, it has good water resistance, acid and alkali resistance, weather resistance and light aging resistance. It has good solubility in organic solvents, especially in petroleum solvents, similar to other resins. The compatibility is very good, and it also has brittleness, viscosity increasing, cohesiveness and plasticity. It is generally not used alone, but as an accelerator, regulator, modifier and other resins.ã??
Product application areas:
C5/C9 copolymerized petroleum resin is used in hot melt adhesives, synthetic rubber, adhesives, paints, rubber soles, tires, etc., and is suitable for high-demand rubber products such as radial tires. It can not only increase the adhesion between the rubber particles, but also It can improve the adhesion between the rubber particles and the cord. In the field of hot melt adhesives, adhesives, and adhesives, C5/C9 copolymerized petroleum resin can not only provide better initial viscosity, but also can be used like rosin resin. To adjust the durability and bonding strength of the glue and resin mixture. It can be used as a substitute for terpene resin, rosin glyceride, etc.
Resins characters:
Light colored and transparent granule
Make the initial adhesion performance; cohesive strength and peel strength reach the best balance
Super aging resistance performance
Good fluidity which can improve the wetting property of master material.
Narrow molecular weight distribution
Low volatility and no odor
Excellent compatibility with cinnamene copolymers (such as sis, sbs, sebs and seps), nr, sbr, eva and natural sticky resins(such as terpene, gum resin and its ramification).
Application:
Hot melt adhesive, solventborne adhesive, pressure sensitive adhesive, rubber compounding, tyre.
Alkyd resin is a resin synthesized from alkyd and polyacid. Due to the side effects such as internal esterification and etherification that occur during the esterification reaction between multivalent alcohols and polyacids, a resin formation reaction with extremely complex structure occurs. The specific gravity of alkyd resin is 2.16-2.24, with a heat resistance temperature of 210. It is opaque and has excellent chemical corrosion resistance. Its main use is as a seasoning and adhesive for coatings.
C5 Hydrocarbon Resin PZX-J Series

Application fields recommended
Label adhesive, Adhesive sticker, Sanitary adhesive, instruction adhesive, Hot melt adhesive, Hot melt pressure-sensitive adhesive, Sealant, Mixing of rubber, Rubber products etc.
As a modifier for polymers, tackifying resins are rarely used alone. In most cases, they are used as compounding agents to enhance the adhesion of polymers, improve initial tackiness, and reduce viscosity during operation or processing. Its application fields include hot melt adhesives, pressure-sensitive adhesives, coatings, inks, rubber complexes, and hydrocarbon modifiers, etc. It can be seen that most of the applications of tackifying resins are combined with rubber, so tackifying resins can also be discussed as tackifying agents for rubber. The only slight difference is that in the rubber products or tire industry, the usage of tackifying resins as compounding agents is much lower than that in industries such as adhesives.
C5 petroleum resin is an aliphatic petroleum resin widely used in tire rubber mixing. It has good compatibility with natural rubber (NR), synthetic rubber, polyethylene, SIS, SEBS, EVA, etc., and is tackified with natural Resins (such as terpenes, rosin and their derivatives) are also compatible.In rubber mixing, it can be used as tackifier, reinforcing agent, softener, filler, etc.
In rubber mixing 1. It has excellent viscosity increasing 2. It can play a role of softening and strengthening during processing, improving tretchability and peeling resistance 3. Significantly improving the stickiness, but does not affect the vulcanization time and after vulcanization The physical perties of 4. Avoid adhesion to processing machinery 5. Help the filling material to be evenly distributed 6. The color is moderate
Application areas:
Other rubber products, such as tires, shoe soles, heels, floors, belts, rubber tubes, inner tubes, light-colored rubber daily necessities, etc.
