Hotmelt TPU, Fast Crystallization, Strong Initial Adhesion, For Adhesive Films

Hotmelt TPU, Fast Crystallization, Strong Initial Adhesion, For Adhesive Films

Product Description

DHMA-98A-3 is a high-performance hotmelt TPU engineered for versatile processing methods including solvent processing, injection molding, extrusion, and calendering. It features excellent physical properties, fast crystallization, strong initial strength, and superior solvent solubility, enabling low-temperature lamination. Perfect for low-temperature chemical sheets, fire hose co-extrusion, hotmelt adhesive films, and fabrics lamination, it meets industrial demands for reliability and adaptability.

Its outstanding performance in low - temperature environments allows for efficient production processes. The fast crystallization rate ensures quick setting during manufacturing, reducing production time and costs. The strong initial strength provides immediate structural integrity, which is crucial for applications like fire hose co - extrusion where early stability is essential.

Moreover, its superior solvent solubility makes it an ideal choice for solvent - based processing methods. This property allows for easy integration into various production setups, enhancing the versatility of the material. In the production of hotmelt adhesive films, the excellent physical properties contribute to the film's durability and performance.

When used for fabrics lamination, DHMA - 98A - 3 ensures a strong bond between different fabric layers, even at low temperatures. This not only improves the quality of the laminated fabrics but also expands the range of possible fabric combinations. Overall, its ability to meet industrial demands for reliability and adaptability makes it a highly sought - after material in the market.

Relationship with Polyurethane​
DHMA-98A-3 is a specialized hotmelt thermoplastic polyurethane (TPU) variant, inherently belonging to the polyurethane (PU) material family . Polyurethanes are a broad class of polymers formed by reacting diisocyanates with polyols, and TPU represents their thermoplastic subclass,distinguished by a segmented molecular structure of hard and soft chains .​
DHMA-98A-3 inherits polyurethane’s core advantages. Its hard segments provide tensile strength and heat resistance via intermolecular hydrogen bonds, while soft segments (polyether/polyester) deliver rubber-like elasticity . However, it is engineered with hotmelt-specific modifications: components added to enhance solvent solubility and accelerate crystallization, while preserving the base PU’s mechanical robustness . This makes it an optimized PU solution that bridges standard TPU versatility and the efficient bonding demands of hotmelt applications.​

Product Applications​
Leveraging its balanced performance,fast crystallization, low-temperature lamination, and high tear strength, DHMA-98A-3 serves diverse industrial needs.
1.Low-Temperature Chemical Sheets.Bonds delicate substrates without thermal damage, ideal for sensitive composite materials .​
2.Fire Hose Co-Extrusion. Reinforces structural integrity and water resistance through reliable interlayer adhesion, critical for high-pressure utility.​
3.Hotmelt Adhesive Films. Acts as a core bonding material for plastics, fabrics, and metals, enabling durable, flexible joins in packaging or electronics.​
4.Fabric Lamination. Creates composite textiles,such as, outdoor clothing, with strong adhesion and flexibility, suitable for sportswear or automotive interiors.​
Its compatibility with processes like extrusion, injection molding, and calendering further expands its utility across manufacturing sectors.​
