1100 Series

P- Tert-Octyl Phenol-Formaldehyde

White to light yellow pieces/particles

85~135

-

≤4.0

30~54

@600℃ <0.5


The alkyl of the p-teroctyl phenol formaldehyde viscosifying resin is in the counterpoint of the phenolic hydroxyl group, and no chemical reaction at the curing temperature, with non-thermal reactivity.

1200 Series

Para-Tert-Butyl Phenol-Formaldehyde

White to light yellow pieces/particles

125~133

-

<3.5


@600℃ <0.5

≤0.5

The resin with viscosification of tert-butyl formaldehyde will not have chemical reaction under curing temperature, which has non-thermal reactivity, excellent viscosification, and good compatibility with all kinds of rubber. It is an excellent viscosifying accelerator for all kinds of rubber.

<3.0

25~60

@600℃ <0.5

≤0.5

Used as synthetic rubber and natural rubber adhesion promoter, especially for butyl benzene, nitrile, neoprene, suitable for high viscosity requirements of tire and rubber products, and easy to dissolve, no dust.

Reinforcing Resin

Tall oil modified Phenol- Formaldehyde

Brown pieces/particles

92~103

@130℃,10%HEXA

5.5~7.5

≤2.5


@800℃

≤0.5


Used together with methylene donor, such as HMT or HMMM, the hot curing reaction can improve the hardness, tear strength, wear resistance, strength and elongation of the adhesive.

4.0~7.0

≤2.0


@800℃

≤0.5


Reduce viscosity during rubber compound processing and is conducive to the dispersion of fillers, and prolong the role of coke burning time, mainly applied in the bead.

Bonding Resin

3100 Series

Resorcinol- Formaldehyde

Bronzing granule/ particles

98~110

@120℃,10%HEXA

2.0~3.5

1.5~4.0



≤0.5

Resorcinol -formaldehyde and methylene vulcanize rapidly under vulcanizing temperature. Stress at definite elongation of vulcanized rubber decrease. Tensile and adhesive strength increase. Good bonding performance makes the adhesive strength between the material and fiber or wire much higher. Thus it can improve durability of the tire.

Curing Resin

4000 Series

Alkylphenol formaldehyde resin with methylol group

Yellowish block(flake)

100~125






The main component is to the tert-butyl phenolic thermal reaction resin, is an adhesive,.

mainly used for neoprene adhesive, suitable for contact adhesive formnula system, with 

highviscosity, high temperature stability, low elongation and other excellent performnance.
