Low Heat-Generation Bio-based Silica

Core Features

1. Core Advantage of Low Heat Generation

   The special particle size distribution and porous structure design effectively reduce stress concentration and intermolecular friction loss inside the material. In dynamic service environments (such as tire treads and transmission belt rubber products), it can reduce the heat accumulation rate and peak temperature, improve the thermal aging resistance and service life of products, and reduce energy consumption.
2. Environmental Sustainability

   Derived from renewable biomass, it replaces the production path of traditional petrochemical-based silica, reducing carbon emissions by more than 30% during production (typical value). The product can achieve natural circular degradation, complying with EU REACH, RoHS and domestic green material-related standards, and meeting the low-carbon development needs of downstream industries.
3. Excellent Reinforcement and Compatibility

   After surface modification with organosilane, the interfacial bonding force with rubber, resin and other substrates is significantly improved, which can effectively enhance the tensile strength, tear strength and wear resistance of materials. It also has good dispersibility, is not easy to agglomerate, and is suitable for various systems such as water-based and oil-based systems.
4. Multifunctional Additional Value

   In addition to low heat generation and reinforcement functions, it also has certain heat insulation and insulation properties. It can be used as a battery separator coating material to improve thermal stability, or as a coating additive to enhance the weather resistance and scratch resistance of coatings.

Technical Parameters (Typical Values)

Application Fields

1. Rubber Industry: As a reinforcing agent for tire treads, shock-absorbing rubber, and transmission belts, it reduces heat generation in rubber products during high-speed operation or high-frequency vibration, improves the explosion resistance and cruising range of tires, and is suitable for high-end products such as new energy vehicle tires.
2. Coatings and Adhesives: Used in high-temperature resistant coatings and low-energy consumption curing adhesives, it reduces heat release during processing, avoids substrate deformation due to high temperature, and enhances the mechanical properties of coatings.
3. New Energy Field: As a battery separator coating material, it improves the thermal stability and safety of batteries by virtue of its low heat generation and heat insulation properties; it can also be used for the modification of fuel cell proton exchange membranes.
4. Plastic Modification: Added to engineering plastics, it reduces heat accumulation during high-speed processing, improves processing fluidity, and enhances the heat resistance and mechanical strength of plastics.

Usage Recommendations

1. Addition Level in Rubber Systems: The recommended mass fraction is 5%-20%, which can be adjusted according to the substrate type and performance requirements. It can be used in combination with carbon black and other reinforcing agents.
2. Dispersion Method: Use high-speed shear dispersion or internal mixer mixing, and control the mixing temperature at 80-120℃ to avoid decomposition of modifiers due to high temperature, which affects dispersion effect and low heat generation performance.
3. Storage Conditions: Seal and store in a cool and dry place to avoid moisture and caking. The shelf life is 18 months.
