Thermoplastic polyurethane (TPU pellets)

Description

1. Product Overview

Thermoplastic Polyurethane (TPU pellets) are a high-purity elastomer combining the performance of rubber with the processability of thermoplastics. They are primarily used in automotive, footwear, hose & tube, and industrial cable sheathing. The key value proposition is exceptional mechanical strength, transparency options, and adhesion to various substrates. Strategically, TPU is replacing conventional materials in high-wear applications, driven by its recyclability and long lifecycle cost efficiency.

2. Key Specifications & Technical Characteristics

• Chemical composition: Polyester-based or polyether-based TPU (customizable isocyanate/polyol ratio)

• Purity level: ≥ 99.5% virgin polymer; low-odor, low-fogging grades available

• Physical characteristics:

  • Form: Free-flowing cylindrical or lenticular pellets (2–4 mm)

  • Color: Natural (off-white/translucent) or custom-matched solid colors

  • Hardness range: Shore 60A to 70D

  • Density: 1.10 – 1.25 g/cm³

  • Melt flow index (MFI): 5 – 50 g/10min (190°C/5kg, grade-dependent)

• Packaging options: 25 kg moisture-barrier bags; 500 kg & 1,000 kg FIBC bulk bags; anti-static liners upon request

• Shelf life: 12 months in original unopened packaging stored at 15–25°C (<60% RH)

3. Core Industrial Applications

• Automotive: Cable jacketing, instrument panel skins, interior trim – outperforms PVC in low-temperature flexibility (-40°C) and hydrolysis resistance.

• Footwear: Sport shoe soles, safety toe caps, ski boot components – delivers 3× higher abrasion resistance than rubber and reduces cycle time by 20% vs. casting.

• Industrial hose & tubing: Pneumatic lines, fuel lines, hydraulic seals – resists oil, grease, and microorganism attack (polyether grade), enabling longer service intervals.

• Wire & cable: Maritime cable jackets, robotic arm cables – offers flame retardance (UL 94 V-0 grades available) and high tear strength, lowering field failure rates.

4. Competitive Advantages

• Quality consistency: Lot-to-lot viscosity and hardness variance < ±2% via ISO 9001:2025 production with real-time SPC monitoring.

• Supply reliability: Dual-sourced raw material agreements and three regional warehouses (Asia, EU, NAFTA) ensuring 98%+ on-time-in-full delivery.

• Logistics capability: Dangerous goods not classified; ambient container shipping with moisture-control desiccants included.

• Price competitiveness: Direct-from-manufacturer pricing removes 2–3 distribution layers; volume rebates for >100 MT/month.

• Sustainability: 100% recyclable process waste; bio-based TPU grades (up to 65% renewable content) available with ISCC PLUS certification.

• Technical support: Full TDS, MSDS, injection molding parameters, and failure analysis included free for contract buyers.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20 MT (partial pallet samples available 100–500 kg at premium rate)

• Loading capacity: 24 MT per 20-ft standard container (palletized, 25 kg bags); 22 MT per 20-ft container (FIBC bulk bags)
