Many different chemical elements are used in the production of rubber pulp.One of these elements is Colophon resins(Gum Rosins) obtained from pine trees and are important components that increase the homogeneity of the dough they enter. In the production of rubber pulp, colophon resin (Gum Rosin), as a binder to provide a homogeneous mixture of rubber, fillers and other additives, allows the rubber pulp to combine permanently with its adhesive property and take the desired shape.
Colophon resin(Gum Rosin) provides elasticity and flexibility to rubber pulp and thus ensures that rubber products can withstand mechanical stresses such as bending, stretching and deformation in various applications.In addition, Colophon Resin (Gum Rosin) provides temperature stability in the rubber pulp, allowing the rubber to maintain its adhesive properties even when exposed to high temperatures

Resins are used for different purposes in the rubber and tire sectors as reinforcing, curing, adhesive and adhesive.
Reinforcing Resins: Colophon Resins (Gum Rosin) provide better hardness, reduced compression and better durability, heat, oil and solvent resistance in the products by increasing the tear resistance, initial tear resistance and wear resistance properties of the rubber used.
Curative (Curing) Resins: Curative resins designed to show thermal reactivity are used to improve the curing performance, especially in the vulcanization process of butyl rubber pulp. In addition, it can also be used in blends of butyl rubber and nitrile, natural rubber and polychloroprene rubbers.

The most widely used, cheapest and oldest rubber curing/vulcanization method today is the use of sulfur-containing chemicals. The use of phenolic resins as a curing agent provides advantages over other methods. Carbon-sulfur bonds are formed in rubber when curing in the presence of sulfur, while carbon-carbon bonds are formed when curing with phenolic resin. Carbon-carbon bonds are much more resistant to hydrolysis than carbon-sulfur bonds, especially when exposed to moisture at high temperatures. In rubber cured with sulfur curing technology, the disintegration reaction of carbon-sulfur bonds is observed after the crosslink density increases to the maximum level. On the other hand, in rubbers cured with phenolic resin, the reverse reaction occurs much slower and is gaining importance in some special applications with this feature.
Resins in this group are used together with halogen-containing elastomers and metal chloride catalysts. With the use of these resins, vulcanized butyl rubbers become products that are resistant to drying, high heat and pressure, do not bloom, do not stain and have high modulus values.

Adhesive (Tackifying) Resins:
Resins developed for use as interlayer adhesive during the Decaleration production of automotive tires and mechanical rubber products requiring high adhesion levels are compatible with synthetic rubber and natural rubber blends.
With today's technology, increasing synthetic rubber performances are replacing natural rubber. However, the ability to hold the layers together, which is the greatest feature of natural rubber, is not as strong in synthetic rubbers as in natural rubber. Dec. Adhesive resins are used in rubber pulps used in the production of various products such as automotive tires, conveyor belts, rubber-based hoses, liners, mats, sheets, fabric-lined rubber and rubber adhesives.
Adhesive Resins:
Adhesive resins are formulated to be thermally activated and synthesized in accordance with neoprene, chloroprene and other elastomer-based adhesives. These resins give rubber-based adhesives low initial viscosity and viscosity stability. These adhesive resins are produced by taking into account parameters such as green bonding, opening time and bonding force.
These resins, soluble in solvents such as aromatic hydrocarbons, esters and ketones, are used in areas such as rubber-based adhesives, upholstery, footwear, leather, automotive adhesives, wire enamel, coating and lacquering.
