Hotmelt TPU, Fast-Crystallization, Low-Temp Lamination Grade For Adhesive Films, Fabric Lamination And Fire Hose Co-Extrusion

Product Description

DHMA-98A-3 is a high-performance hotmelt TPU of Dingzhi’s DHMA series, adaptable for solvent processing, injection molding, extrusion and calendering. It features fast crystallization, excellent solvent solubility and reliable low-temperature lamination performance, paired with superior mechanical properties like high tear strength and ultra-flexible breaking elongation. This material delivers strong initial adhesion and stable physical performance, making it an ideal choice for producing hotmelt adhesive films, fabric lamination products, low-temperature chemical sheets and fire hose co-extrusion components, meeting the rigorous processing and application demands of industrial bonding and extrusion fields.

Core Property Ranking

Dingzhi’s DHMA series hot-melt TPU is a top-tier TPU variant for fast crystallization, low-temperature lamination and solvent solubility, with industry-leading ring and ball softening point control and initial adhesion strength. It also excels in versatile process ability (solvent processing, injection molding, extrusion, calendering) and robust mechanical performance, integrating core hot-melt functionality and superior physical properties.

Working Principle

Based on TPU’s thermoplastic characteristics, our hot-melt TPU is engineered via molecular structure optimization and functional modifier blending. It works through thermoplastic melting and rapid crystallization: melting into a fluid at the matching processing temperature, wetting and spreading on substrates to form adhesion, then crystallizing fast at room or low temperature for high initial and permanent bonding strength. Its optimized molecular chain also ensures excellent solvent solubility for multi-scenario solvent-based bonding.

Guidance to Maximize Product Advantages

(1)Model Selection by Scenarios And Processes

· Fabric lamination or adhesive films: DHMA-98A-3,fast crystallization, high bonding strength, anti-delamination for textiles or composites.

· Fire hose co-extrusion or low-temp chemical sheets: DHMA-98A-4, excellent low-temp lamination and extrudability for continuous pipe or sheet production.

· Solvent-based bonding: DHMA-98A-5,superior solvent solubility, ensures uniform mixing and stable coating or adhesive effects.

(2)Optimize Processing Parameters

· Control temperature per softening point to avoid degradation and ensure optimal substrate wetting fluidity.

· Stabilize cooling rate for extrusion or calendering: accelerate crystallization, shorten curing time and boost production efficiency.

· Follow recommended solvent ratio for solvent processing: maximize solubility for even, bubble-free adhesive coating.

(3) Cut Production Costs with Multi-performance Merits

· One-material multi-process adaptability: universal for injection molding, extrusion and calendering, reducing inventory and material management costs.

· Low-temperature lamination: stable bonding without thermal damage to heat-sensitive substrates (thin chemical sheets, delicate fabrics), eliminating post-repair and shortening production cycles.

· Compatible with conventional TPU processing equipment, no special modification needed for fast production line switching.

(4) Boost Product Competitiveness

· Highlight strong initial And permanent bonding: unlike conventional hot-melt adhesives, it retains excellent adhesion and toughness post-bonding, meeting high durability demands for fire hoses, fabric composites and industrial adhesive films.

· Emphasize integrated bonding And functionality: combines hot-melt adhesion with TPU’s inherent wear resistance, flexibility and tear resistance, realizing one-step bonding and performance enhancement for end products.

· Leverage eco-friendly formula: free of harmful volatile substances, compliant with EU or North American environmental standards, helping customers pass international certifications and expand overseas markets.
