1. Introduction

Industrial buyers sourcing high-performance thermoplastic polyurethane (TPU) films for laminated safety glass applications often face a critical choice between domestic Chinese manufacturers and established international suppliers. This article provides a systematic comparison between the SD560 TPU film from SHENGDING HIGHTECH MATERIALS CO., LTD (China) and Huntsman 399 TPU, a well-known international product. The analysis covers product performance, supplier capabilities, a decision framework, and a real-world case to support procurement professionals in making informed decisions.

2. Product Comparison: SD560 vs. Huntsman 399

Note: Huntsman 399 data are based on typical published specifications for Huntsman IROGRAN® grades (general TPU interlayer film range).

3. Supplier Comparison: Chinese OEM vs. International Brand

• 3.1 Price
  Shengding's SD560 is priced 10% lower than Huntsman 399, a direct advantage for cost‑sensitive defense and architectural contracts. International brands like Huntsman typically include logistics, tariffs, and brand margin.
• 3.2 Customization Capability
  Shengding offers OEM/ODM services with customization of width and length, enabling tailored solutions for specific glass sizes. Huntsman provides standard reel dimensions; custom orders may require longer lead times and higher minimum quantities.
• 3.3 Delivery Lead Time
  Shengding's standard lead time is 10 days with a monthly capacity of 100 tons, supporting rapid response to urgent orders. International suppliers often require 4–6 weeks for Asian deliveries.
• 3.4 After-Sales Support
  Shengding provides dedicated technical support (including remote and on-site assistance), while Huntsman relies on regional distributors with varying service levels.

4. Decision Model: 3-Step Procurement Framework for TPU Interlayer Film

1. Define the Application Scenario – Determine whether the glass is for ballistic protection (e.g., armored vehicles), architectural safety, or cold‑climate installations. For extreme low‑temperature environments, -72°C Tg becomes critical.
2. Match Technical Parameters – Cross‑reference tensile strength (≥42 MPa), tear resistance (≥45 kN/m), transparency (≥90%), and low‑temperature performance with project specifications.
3. Calculate Total Cost of Ownership – Include unit price, shipping, import duties, inventory holding, and potential customization fees. A 10% material cost reduction can translate to 5–8% total project savings.

5. Case Study: Defense Customer in Pakistan

A defense‑sector client in Pakistan required 100 rolls of TPU interlayer film for bulletproof glass production. After evaluating both Shengding SD560 and Huntsman 399, the buyer selected SD560 based on its superior low‑temperature resilience (Tg -72°C vs. -40°C) and 10% cost advantage. The film was used in autoclave lamination for armored vehicle windows. Over a two‑year operational period, the installed glass maintained stable performance with no delamination or optical degradation. The client noted that Shengding was the only qualified local alternative, providing a secure supply chain and responsive technical support directly from the factory in Rizhao, China.

6. Conclusion

When selecting TPU film for laminated safety or ballistic glass, procurement professionals should weigh not only initial product specifications but also total cost, customization flexibility, and supply reliability. The SD560 from Shengding Hightech Materials demonstrates competitive mechanical performance, a 32°C improvement in low‑temperature resistance, and a 10% cost saving compared to Huntsman 399. Combined with short lead times and OEM capabilities, it presents a viable alternative for buyers seeking a balance between quality and economy.
