Impregnated Chopped Fiber

Short Description:


Product Overview: 

Impregnated chopped fiber is a high-performance fiber reinforcement material that undergoes precision surface coating treatment. This product, through a unique gumming process applied to synthetic fibers of specific lengths and linear densities, significantly enhances their dispersion and interfacial bonding within various matrices (such as rubber, plastics, asphalt, etc.). It is the ideal choice for optimizing the physical and mechanical properties of composite materials.

Principle & Core Advantages: 

1. Enhanced Interfacial Bonding: The specialized gumming layer acts as a "bridge" between the fiber and the matrix, effectively transferring stress and preventing interface debonding, thereby substantially improving the integrity of the composite material.

2. Improved Processing Dispersion: The gumming treatment effectively reduces static electricity between fibers, preventing clumping and enabling rapid, uniform dispersion during mixing, ensuring consistent performance in the final product.

3. Superior Comprehensive Performance: By leveraging the reinforcing effect of the fibers, it significantly improves the tensile strength, impact resistance, wear resistance, fatigue resistance, and dimensional stability of the composite material.


Primary Application Fields: 

1. Friction & Sealing Materials: Used in brake pads, clutch facings, brake blocks, gaskets, etc., to improve wear resistance, thermal stability, and reduce noise.

2. Rubber Product Reinforcement: Widely used in tires, hoses, conveyor belts, sealing strips, etc., to significantly enhance product strength, tear resistance, and durability.

3. Engineering Plastics Modification: Used to reinforce Nylon (PA), Polypropylene (PP), Polyester (PBT), etc., improving the mechanical strength, stiffness, and heat deflection temperature of plastic components.

4. Building Materials: Used in asphalt modification (SMA), waterproof membranes, composites, etc., to enhance the tensile strength, crack resistance, and fatigue resistance of the materials.


Usage Guidelines: 

1. Storage Conditions: Store in a cool, dry place away from moisture and direct sunlight. Use within 6 months for optimal performance.

2. Mixing Process: It is recommended to add at the initial stage of mixing, along with powders or pellets, to ensure uniform dispersion.

3. Safe Handling: Appropriate dust masks are recommended during handling to minimize inhalation risk.
