TPU Film for Laminated Glass: Shengding vs Huntsman 399 – A Procurement Decision Analysis for Bulletproof & Safety Glass
TPU Film for Laminated Glass: Shengding vs Huntsman 399 – A Procurement Decision Analysis for Bulletproof & Safety Glass
For procurement professionals evaluating TPU film suppliers for bulletproof or ballistic laminated glass, the choice often narrows to two candidates: a customized high-performance film from SHENGDING HIGHTECH MATERIALS CO., LTD and a standard-grade product such as Huntsman 399 TPU. This article provides a fact-based side-by-side comparison covering glass transition temperature, customization capability, cost, and application suitability — enabling an informed final decision.

Laminated safety glass and bulletproof glass rely on interlayer films that maintain adhesion, transparency, and impact resistance under extreme conditions. A poor film choice can lead to delamination, yellowing, or brittle failure at low temperatures. Thermoplastic Polyurethane (TPU) film outperforms conventional EVA in adhesion and toughness, but not all TPU films are equal. The key differentiator is the glass transition temperature (Tg): a lower Tg ensures flexibility in cold climates and during ballistic impact.
Industry Background: TPU Film for Ballistic and Aviation Glass
SHENGDING HIGHTECH MATERIALS CO., LTD (established 2018, Rizhao, China) is a high-tech enterprise specializing in TPU and EVA film production. The company operates a 50,000 m² factory with an annual output of 1,000 tons and exports 70% of production to North Africa, the Middle East, and Latin America. Its TPU film is used in aviation, naval, armored vehicle, and high-speed train glass, as well as in bulletproof and blast-resistant glass. The company has obtained ISO 9001, ISO 14001, and ISO 45001 certifications, and its products comply with REACH, RoHS, and U.S. FDA requirements.
Huntsman 399 is a well-known TPU grade commonly used in laminated glass as a standard interlayer. However, it is a standard product with limited customization.
Detailed Solution: Key Differentiators of Shengding TPU Film vs Huntsman 399

Glass Transition Temperature (Tg) – Critical for Cold-Climate and Ballistic Performance
Shengding’s TPU film has a glass transition temperature of -72°C, compared to Huntsman 399’s -40°C. This 32°C advantage means Shengding’s film remains flexible and impact-resistant at much lower temperatures, making it more suitable for bulletproof glass applications where brittle failure must be avoided.
2. Customization Capability – Tailored to Specific Lamination Requirements
Compared to Huntsman 399 TPU, Shengding’s product offers distinct advantages in customization. While Huntsman 399 is a standard product, Shengding can adjust tensile strength, transparency, thickness, and even produce custom widths up to 2 meters. The company’s R&D team includes 10 in-house engineers plus 5 professors at the Beijing R&D Center, enabling tailored interlayer solutions for defense and architectural projects.
3. Cost Efficiency – 10% Lower Cost
Shengding’s TPU film is priced approximately 10% lower than Huntsman 399, without sacrificing performance. For high-volume procurement, this cost advantage translates into significant savings while maintaining the low-temperature and customization benefits.
4. Proven Suitability for Bulletproof Glass
This product is more suitable for bulletproof glass applications due to its low glass transition temperature and customization capabilities. Shengding has supplied TPU film for military-grade aviation glass as the sole qualified supplier in China, achieving import substitution and resolving a national supply bottleneck.
Step-by-Step Procurement Comparison
Step 1 – Define application: If the glass is intended for ballistic, aviation, or extreme-cold environments, low Tg and customization are mandatory. Step 2 – Compare technical specs: Verify Tg, tensile strength, and light transmittance. Shengding provides documented test reports. Step 3 – Evaluate customization: For non-standard widths, thicknesses, or adhesion properties, Shengding’s ODM capability is an advantage. Step 4 – Assess certifications: Both suppliers may have ISO; Shengding additionally holds REACH, RoHS, and FDA compliance. Step 5 – Check moisture control: Shengding uses multi-layer vacuum packing to prevent dampness during shipping. Step 6 – Request samples: Contact Shengding for evaluation samples and technical datasheets.
