TPUとTPUの対比. TPHと比較. PVC製PaTPUと比較. TPHと比較. PVC塗料保護フィルム (PPF)

塗装保護フィルム (PPF) can be used to protect car paint against rock chips, 傷, 紫外線, and normal wear. Even though all the types of PPF have the same basic functionality, their material of manufacture radically varies in terms of performance, 柔軟性, 耐久性, およびコスト. The three key materials in the PPF, which are TPU, TPH, and PVC, are divided into this 2026 比較.

1. TPU PPF (熱可塑性ポリウレタン)

熱可塑性ポリウレタン (TPU) is the most widely used and highest-performing PPF material. It is valued for its flexibility, 光学的鮮明さ, 耐久性, and advanced protection features.

主な特徴:

• Superior flexibility and ease of installation on curved surfaces

• Excellent resistance to UV, 化学薬品, and environmental wear

• 自己治癒: minor surface scratches can disappear with heat

• Long life span with minimal yellowing or degradation over time

TPU films offer the best balance of protection, 様子, そして寿命, making them the premium choice for car owners and enthusiasts.

2. TPH PPF (熱可塑性ハイブリッド)

熱可塑性ハイブリッド (TPH) is a mid-range PPF material designed to combine features of both TPU and traditional plastics like PVC. It’s often chosen by those who want better performance than PVC at a lower price than pure TPU.

Key Characteristics:

• More impact-resistant than PVC, yet more affordable than TPU

• Good basic protection against scratches and wear

• Less flexible and no self-healing compared to TPU

• Suitable for moderate protection needs without premium cost

TPH film is ideal if you want a balance of durability and cost-effectiveness, though it doesn’t offer TPU’s advanced features.

3. PVC PPF (ポリ塩化ビニル)

ポリ塩化ビニル (PVCです) is the most basic and budget-friendly PPF material. It provides fundamental protection but lacks the performance enhancements of the other two materials.

Strengths and Limitations:

• 低コスト, accessible for budget-conscious buyers

• Protects against minor scratches and contaminants

• Rigid and less flexible — can be hard to install on complex curves

• More prone to yellowing and cracking over time due to environmental exposure

PVC films are a low-cost option but tend to wear out sooner and offer less advanced protection compared to TPU or TPH.

Which PPF Material Is Best for You?

• Choose TPU if you want premium performance, maximum durability, and long-term protection.

• Choose TPH if you want a balance of performance and price with decent everyday protection.

• Choose PVC only if you are on a tight budget and need basic coverage.

Wrap-Up

The choice of PPF material can huge difference on the extent at which the paint on your vehicle will be preserved through the years. Although all three solutions, TPU, TPH and PVC, provide a certain degree of paint protection, TPU is the best in terms of performance and durability, TPH is the solution with a middle-price range and PVC is the one with the simplest and the least expensive protection.
