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.
