Why Leading Rubber Manufacturers Choose HA-40

In the competitive rubber industry, consistency, efficiency, and product performance define success. That’s why leading rubber manufacturers around the world trust HA-40, our premium pre-dispersed masterbatch designed to simplify rubber compounding while improving production stability and end-product quality. With advanced formulation technology and proven industrial performance, HA-40 helps manufacturers achieve higher output, smoother processing, and more uniform rubber properties.

Product Function and Application

HA-40 is a pre-dispersed masterbatch used to deliver active rubber chemicals in a carrier that allows faster and more uniform dispersion into various rubber compounds. It functions as both a processing aid and curing accelerator, enabling precise control of curing rates and improving compatibility with multiple elastomer systems such as NR, SBR, NBR, EPDM, and CR.

By integrating HA-40 into your rubber formulations, you can significantly reduce mixing time, enhance dispersion uniformity, and minimize compound scorching risks. It is widely used in tire production, rubber seals, hoses, belts, industrial gaskets, and molded rubber parts where durability and dimensional stability are essential.

Product Features

HA-40 is engineered with precision to meet the needs of modern high-volume rubber manufacturing. Its key features include:

• Excellent Dispersion Performance: The active ingredients are uniformly distributed in a polymeric carrier, ensuring fast and complete incorporation during mixing.
• Stable Chemical Activity: The product retains consistent reactivity under high-temperature conditions, ensuring reliable curing performance.
• Improved Processing Efficiency: HA-40 simplifies compounding steps by eliminating the need for manual dosing of raw accelerators or additives.
• Dust-Free and Cleaner Production: The pre-dispersed form minimizes airborne particles, creating a safer, cleaner working environment.
• Enhanced Product Quality: Using HA-40 results in smoother surface finishes, fewer defects, and better mechanical properties in finished rubber goods.

These advantages make HA-40 an indispensable choice for manufacturers seeking both performance and productivity in their rubber production lines.

Product Specifications and Parameters

Each batch of HA-40 undergoes strict quality control to ensure consistent dispersion performance, uniform particle size, and thermal stability.

Product Usage Instructions

For optimal performance, HA-40 should be added during the final mixing stage of rubber compounding. Ensure uniform blending for 3–5 minutes to achieve complete dispersion. It can be used alone or in combination with other pre-dispersed agents or accelerators, depending on the desired cure rate and compound formulation.

Avoid overheating during mixing to prevent premature curing. Store the product in a cool, dry place, away from direct sunlight and heat sources. Before use, make sure the packaging is sealed properly to avoid moisture absorption.

Applicable Industries

HA-40 has been successfully adopted in a wide range of rubber-related industries, including:

1. Tire Manufacturing: For tread, sidewall, and inner liner compounds, improving uniformity and curing balance.
2. Automotive Components: Used in rubber seals, mounts, bushings, and hoses to enhance durability and heat resistance.
3. Industrial Rubber Goods: Ideal for belts, gaskets, vibration isolators, and conveyor systems.
4. Consumer and Footwear Products: Ensures color consistency and elasticity in shoe soles and molded rubber items.
5. Electrical Insulation Materials: Provides stable performance in high-voltage rubber components and protective coatings.

Its versatility allows manufacturers across different segments to streamline their production processes while maintaining superior product quality.
