Description: Tall oil modified thermoplastic phenol-formaldehyde resin without hexamethylenetetramine (HMT)

Characteristics

Property

1. This product is a high performance reinforcing resin. This product should be used along with another methylene donor, such as hexamethylenetetramine (HMT) or hexamethoxymethylmelamine (HMMM), in the rubber compounding applications. After the cross linking reaction with methylene donor compounds, this product could improve the hardness, tear resistance, wear resistance and tensile strength properties of rubber compounds. In uncured rubber stock, this product could increase the scorch time and lower the Mooney viscosity properties.

2. When this product is incorporated into rubber compounds, it could improve the compound’s filler dispersion and plasticity properties.

3. In order to achieve an optimum reinforcement in rubber compounds, the methylene donor should be used at a level of 10 % based on the amount of this product to obtain the proper cross-linking network structures.

4. This product should be added during the first stage of mixing in order to achieve good scorching and plasticity properties in rubber compounds. The methylene donor should be added with an accelerator and sulfur at the final mixing stage.

5. This product could function as a tackifier, plasticizer and softening agent to rubber compounds prior to vulcanization, and performs as a reinforcing agent after the cross-linking.

Application

This product can be used in the manufacture of tires, rubber coated rollers, window sealants of automobiles, etc. The recommended dosage should be 5-15 phr.

Packaging

25kg, kraft bag inner PE coated.

Storage

This material can be stable for 12 months under the normal storage conditions. However, precautions must be taken to avoid exposure to sunlight and always, store this material in a sealed container under the dry and cool conditions.
