Coace ® W1L-B - ангидридно-модифицированный LLDPE с высокой скоростью прививки и высокой текучестью
Wood plastic composites are materials derived from wood fibers and thermoplastic polymers. The natural incompatibility of wood fibers with polymer matrices frequently leads in poor mechanical characteristics and processability. Coupling agents are added to WPC formulations to promote compatibility and adhesion, resulting in higher mechanical strength and durability.
High fluidity anhydride-modified LLDPE coupling agents are a significant development in the formulation of Wood Plastic Composites. Their capacity to improve interfacial adhesion, improve mechanical characteristics, and limit water absorption makes them an essential component in the development of long-lasting, high-performance WPCs.

- Chemical modification: The anhydride groups grafted onto the LLDPE backbone react with the hydroxyl groups found in wood fibers, generating strong covalent connections that improve interfacial adhesion.
- High Fluidity: This coupling agent’s high fluidity promotes homogeneous dispersion throughout the polymer matrix, allowing for more efficient processing and mixing.
- Compatibility: The modified LLDPE is intended to be compatible with a variety of thermoplastics used in WPCs, including polyethylene (PE), polypropylene (PP), and polyvinyl chloride.
- heat Stability: It retains its qualities under the typical heat conditions of WPC production, resulting in consistent performance.
- Enhanced Mechanical Properties: It increases the tensile strength, flexural strength, and impact resistance of WPCs, making the finished product more robust and long-lasting.
Преимущество
Improved Dispersion: The high fluidity guarantees that the coupling agent is widely dispersed throughout the polymer matrix, resulting in greater contact with wood fibers.
Enhanced Interfacial Adhesion: The chemical connection between the anhydride and hydroxyl groups in wood fibers creates a stronger interface, improving overall mechanical characteristics.
Reduced Water Absorption: The coupling agent improves the compatibility of wood fibers and polymer matrix, reducing water absorption in WPCs and increasing their dimensional stability and durability.
Process Efficiency: The high fluidity allows for easier processing, lowering the energy and time required for compounding and shaping.
Versatility: This coupling agent is compatible with a wide range of thermoplastic matrices, making it an excellent alternative for a variety of WPC compositions.

Типовое применение
Используется в качестве связующего агента для соединений на основе полиэтилена, таких как кабельные соединения LSZH, соединения WPC и т.д.
Используется в качестве связующего звена в процессах соэкструзии между полиэтиленом или сополимерами этилена и различными материалами, такими как полиамиды, EVOH и т.д.
Может быть разбавлен LLDPE или LDPE. Используется в качестве модификатора ударной вязкости для полиамидных условий
Индустрия применения
Construction and building materials: WPCs are commonly used in decking, siding, and fence. These materials are suited for outdoor applications requiring durability and weather resistance because to their increased mechanical qualities and reduced water absorption.
Automotive Industry: WPCs are used for interior components such as door panels, trim, and dashboards. The increased toughness and reduced weight help to improve fuel efficiency and the longevity of automobile parts.
Consumer Goods: WPCs with anhydride modified LLDPE coupling agents improve the mechanical qualities and visual appeal of products such as furniture, storage containers, and playground equipment.
WPCs are used in packing applications such as pallets and crates because they are strong and durable. The coupling agent allows these materials to tolerate heavy weights and severe handling.
