High-Performance Hotmelt TPU DHMA Series For Multi-Process Applications

High-Performance Hotmelt TPU DHMA Series For Multi-Process Applications

Product Introduction
DHMA-98A-3 is a high-performance hotmelt TPU product under the DHMA series, developed by Dingzhi Polymer—a professional raw material manufacturer established in 2008 in Dongguan, China, specializing in TPU modification and high-quality TPU production. As a key model in the hotmelt TPU lineup, it integrates excellent mechanical properties and versatile processability, addressing the demand for reliable bonding and lamination in diverse industries.
In terms of performance, DHMA-98A-3 stands out with well-balanced characteristics. Mechanically, it delivers strong resistance to cracking and stretching. Additionally, it features fast crystallization, good solvent solubility, and low-temperature lamination capability—key advantages for efficient production.Processability is another highlight of DHMA-98A-3. It supports multiple processing methods, including solvent processing, injection molding, extrusion molding, and calendering, adapting to different manufacturing needs of downstream enterprises.

Applications

DHMA-98A-3 is widely used in:
Low-temperature chemical sheets: Leveraging its low-temperature lamination property to bond sheets without damaging sensitive substrates;
Fire hose co-extrusion: Enhancing the hose’s structural integrity and water resistance via reliable bonding;
Hotmelt adhesive films: Serving as a core material for adhesive films to bond plastics, fabrics, and metals;
Fabrics lamination: Creating composite fabrics (e.g., outdoor clothing, upholstery) with strong adhesion and flexibility.

The Relationship between Hot Melt Products and Polyurethane TPU Materials

DHMA-98A-3 is inherently a variant of thermoplastic polyurethane (TPU) material. It inherits the core advantages of polyurethane TPU, such as excellent flexibility, high impact resistance, and good chemical compatibility—traits that ensure it performs reliably in dynamic or harsh environments. Unlike ordinary TPU, Dingzhi Polymer optimizes DHMA-98A-3 with hotmelt-specific modifications: adding components to improve solvent solubility and accelerate crystallization, while maintaining the base polyurethane TPU’s mechanical strength. This makes DHMA-98A-3 not just a “hotmelt material” but a enhanced polyurethane TPU solution, bridging the gap between TPU’s inherent versatility and hotmelt’s efficient bonding needs.
