• Dual-layer structure: The upper layer is a highly elastic grid (Ping-Pong structure), and the lower layer is a dense TPU thick plate, forming a "soft-hard" composite.
• Adjustable hardness: The hardness range can be achieved through the formulation (ratio of hard segments/soft segments) and thickness, ranging from 60 to 95 Shore A.
• Lightweight: Typical density: 1.10 - 1.20 g/cm³, thickness 0.5 - 2 mm, single piece weight < 2 g (size 42).
• High elasticity and rebound: The composite elastic modulus is 12 - 30 MPa, the rebound rate is > 85%, providing foot sole impact absorption and elastic rebound.
• Wear-resistant and oil-resistant: Surface hardness can reach 95 Shore A, resistant to oil and chemical corrosion (acid, alkali, gasoline).
• Anti-slip texture: The Ping-Pong grid naturally forms micropores, combined with sandblasting or laser engraving, can achieve a friction coefficient of more than 0.45 µm.
• Environmentally friendly and recyclable: TPU: It is a renewable thermoplastic material, compliant with REACH and RoHS, and waste can be melted and reprocessed.
• Processing-friendly: Various processes such as hot pressing, hot forming, laser cutting, CNC milling, and stamping can be adopted, with a forming temperature of 150 - 200 °C.
• Hardness: 60 - 95 Shore A (adjustable according to the formula).
• Tensile strength: 30 - 45 MPa (depending on the content of the hard segment).
• Break elongation: 400 - 650% (high elasticity).
• Tear strength: 12 - 20 kN/m (suitable for high-impact areas).
• Wear index: 4 - 5 grades (equivalent to traditional PU materials).
• Oil/Chemical resistance: No deformation after 24 hours exposure to 1% H₂SO₄, 1% NaOH, and gasoline (suitable for outdoor/work shoes).
• Temperature range: -30 °C - +120 °C (not brittle at low temperatures, not soft at high temperatures).
• Absorption rate: < 0.2% (24 hours, moisture-proof and mold-proof).
• Thermal deformation temperature: 80 °C (0.45 MPa, suitable for hot pressing molding).
• Rebound rate: 85 - 92% (commonly used indicator in sports shoes).

• Color/Transparency: Colorable, printable, semi-transparent to opaque (meeting fashion requirements).
• Lightweight + High Elasticity: Reduces the overall shoe weight by 10-15%, enhances energy recovery during running/jumping.
• Combination of rigidity and flexibility: The Ping-Pong grid provides a soft feel, while the underlying TPU offers support and puncture resistance.
• Compatibility of multiple processes: The same material can be processed through stamping, hot pressing, and laser cutting on the same production line, reducing line change costs.
• High durability: Maintains > 90% of the original elasticity after 10k+ impact cycles, extending the shoe's lifespan.
• Anti-slip and safe: The combination of micro-hole structure and surface texture increases the friction coefficient on slippery surfaces by 15-20%.
• Environmentally friendly and recyclable: Waste can be directly melted and reprocessed, meeting green supply chain requirements and enhancing the brand's ESG image.
• Quick prototyping: A 2-3-minute hot pressing process can yield a finished sample, shortening the R&D cycle by 30-40%.
• Color/Pattern Freedom: Dyes can be added at the raw material stage or UV printing can be done later to meet trend customization needs.

• Running shoes: Midsole counter plate, forefoot elastic sheet, with shock absorption and energy rebound functions, thickness 0.8 - 1.2mm, hardness 70 - 80 Shore A.
• Training/fitness shoes: Sole counter plate, side protection sheet, anti-puncture, wear-resistant, anti-slip, thickness 1.0 - 1.5mm, hardness 80 - 90 Shore A.
• Outdoor/mountain climbing shoes: Sole anti-puncture layer, tongue protection sheet, resistant to rock punctures, oil-resistant, low-temperature resistant, thickness 1.2 - 2.0mm, hardness 85 - 95 Shore A.
• Work safety shoes: Sole counter plate, toe protection sheet, shockproof, anti-puncture, oil-resistant, thickness 1.5 - 2.0mm, hardness 90 - 95 Shore A.
• Casual/fashion shoes: Shoe surface decorative sheet, sole counter plate, lightweight, dyeable, textured decoration, thickness 0.5 - 1.0mm, hardness 60 - 70 Shore A.
• Children's shoes: Sole counter plate, heel support sheet, soft and firm, low irritation, wear-resistant, thickness 0.6 - 0.9mm, hardness 65 - 75 Shore A.

The TPU Counter Ping-Pong Sheet features four core characteristics: soft-hard composite, lightweight elasticity, oil and wear resistance, and recyclability. These features provide an ideal solution for counting plates, midsoles, and protective pieces in various types of shoes such as running, training, outdoor, work, safety, and fashion.
Compared to traditional PU, EVA, and rubber, it has significant advantages in elasticity, chemical resistance, and environmental protection. Moreover, its processing technology is flexible and enables quick response to product iterations.
