TPU Particle Brands Used by TECPPF and Their Impact on PPF Performance

1. Lubrizol

Brand Characteristics: Lubrizol is one of the leading global suppliers of TPU, known for its high-performance materials. Their TPU particles are renowned for their superior weather resistance and durability, making them ideal for high-end PPF markets.

PPF Performance Impact:

• Yellowing Resistance: Lubrizol TPU particles offer excellent UV resistance, ensuring that PPF remains clear and transparent over time with minimal yellowing, even with prolonged sun exposure.
• Self-Healing Ability: These TPU particles have exceptional flexibility and elasticity, allowing PPF to self-heal minor scratches at ambient or heated conditions, prolonging the product's lifespan.
• Chemical and Abrasion Resistance: Lubrizol TPU provides excellent resistance to acid rain, bird droppings, and other corrosive substances, while its smooth surface improves abrasion resistance, effectively protecting vehicle surfaces.

Typical Application: Primarily used in high-end transparent PPF products, especially in luxury and premium automotive markets where superior performance is essential.

2. Covestro (formerly Bayer MaterialScience)

Brand Characteristics: Covestro is known for its innovative materials and advanced TPU solutions, particularly in the area of sustainability and environmental friendliness.

PPF Performance Impact:

• Weather Resistance: Covestro TPU particles exhibit excellent UV and oxidation resistance, ensuring that PPF performs well in extreme climates, suitable for global applications.
• Environmental Performance: Covestro leads in eco-friendly materials, with TPU particles that meet strict environmental standards. PPF made from Covestro TPU has lower VOC emissions during production and use, aligning with modern green market demands.
• Impact and Scratch Resistance: Covestro TPU offers strong mechanical properties, providing PPF with robust protection against external impacts and scratches, making it ideal for harsh environmental conditions.

Typical Application: Ideal for markets with a focus on sustainability, particularly those concerned with eco-friendliness and long-term durability in high-end automotive protective films.

3. WanHua Chemical

Brand Characteristics: WanHua is the largest TPU producer in China, offering products with a significant cost advantage. Some of their TPU particles can closely match or reach international performance standards.

PPF Performance Impact:

• Cost-Effectiveness: WanHua TPU particles are highly cost-effective, making them suitable for mid-range or budget-friendly PPF products. While not as high-performing as Lubrizol, they provide adequate tensile strength and abrasion resistance for most customers' needs.
• Yellowing Resistance: WanHua's TPU, such as the imitation Lubrizol TPU used in TECPPF’s TK Series, can achieve around 85% of Lubrizol TPU’s performance. It meets most markets' requirements for durability and clarity.
• Mechanical Properties: WanHua TPU performs well in terms of impact resistance and abrasion protection, making it suitable for cost-sensitive markets that do not require top-tier durability or self-healing performance.

Typical Application: Best suited for mid-range markets or customers with budget constraints, especially in applications where high-end performance is not a priority but reliable protection is still necessary.

4. Huntsman

Brand Characteristics: Huntsman is known for producing high-performance polyurethane materials, with its TPU offering superior durability and chemical stability, widely used in high-end manufacturing and automotive sectors.

PPF Performance Impact:

• Chemical Resistance: Huntsman TPU particles offer outstanding chemical stability and corrosion resistance, ensuring PPF effectively protects against harmful substances like acid rain, tree sap, and oil stains.
• High Gloss and Clarity: Huntsman TPU imparts a high gloss and clarity to PPF, enhancing vehicle aesthetics by maintaining a brilliant, glossy finish over time.
• Self-Healing Performance: Similar to Lubrizol, Huntsman TPU particles provide excellent self-healing capabilities, allowing PPF to repair minor scratches quickly, especially under heat.

Typical Application: Primarily used in high-end markets and luxury car protection films, with products that are known for their high performance and durability.

5. BASF

Brand Characteristics: BASF is a global leader in chemicals, with its TPU materials widely praised for their high mechanical performance and long-lasting durability.

PPF Performance Impact:

• UV Resistance: BASF TPU particles are modified for strong UV resistance, ensuring that PPF does not yellow or discolor over time, even with prolonged exposure to sunlight.
• Mechanical Strength: BASF TPU imparts exceptional tear and tensile strength to PPF, allowing it to withstand significant physical impact and wear, making it suitable for high-durability applications.
• Weather and Self-Healing Performance: In harsh environments, BASF TPU maintains stable performance, particularly in UV resistance and moisture protection. Its self-healing properties are on par with other top brands.

Typical Application: Used in high-durability industrial and automotive applications, especially in regions with extreme weather conditions where the film must endure intense wear and UV exposure.

Conclusion:

• Lubrizol and Huntsman provide the highest level of self-healing ability, yellowing resistance, and mechanical performance, making them ideal for premium markets.
• Covestro emphasizes eco-friendliness and weather resistance, making it suitable for markets focused on sustainability and long-term use.
• WanHua stands out for its cost-effectiveness, serving mid-range markets where high-end performance is not necessary but reliable protection is still essential.
• BASF excels in extreme weather conditions and high-durability applications, providing superior UV resistance and mechanical strength.
