POM 150 grade

Description

1. Product Overview
POM 150 grade is a high-flow, standard acetal homopolymer (Polyoxymethylene) engineered for precision injection molding of complex, thin-walled industrial components. Its primary industrial use lies in producing high-stiffness, low-friction parts for automotive fuel systems, conveyor chain links, and consumer appliance mechanisms. The key value proposition is exceptional dimensional stability combined with rapid cycle times, reducing per-part costs by up to 12% versus generic copolymers. Strategically, this grade is critical for manufacturers seeking to balance mechanical performance with high-volume production efficiency in global supply chains.

2. Key Specifications & Technical Characteristics

• Chemical composition: Acetal homopolymer (POM-H), formaldehyde-based, stabilized for thermal degradation resistance

• Purity level: ≥99.5% active polymer content; additive-free base grade

• Physical characteristics:

  • Form: Free-flowing cylindrical granules

  • Color: Natural white/opaque (can be pre-colored upon request)

  • Melt Flow Index (MFI): 150 g/10 min (190°C / 2.16 kg) – high-flow classification

  • Density: 1.41 g/cm³ (solid); bulk density approx. 0.75 g/cm³

  • Tensile strength at yield: ≥60 MPa

• Packaging options: 25 kg moisture-barrier bags; 500 kg supersacks; 1,000 kg palletized shrink-wrapped units

• Shelf life: 24 months from production date when stored below 40°C in original sealed packaging

3. Core Industrial Applications

• Automotive industry: Fuel system clips, seatbelt retractor gears, and anti-lock braking system (ABS) sensor housings – outperforms nylon with superior creep resistance and dimensional stability under thermal cycling (-40°C to +120°C).

• Industrial conveying: Snap-fit chain links, bearing cages, and wear strips – the high flow enables filling of intricate locking features without sink marks, while the low coefficient of friction (0.15 against steel) extends service life by 30% versus acetal copolymers.

• Consumer appliances: Coffee machine brew group components, hairdryer fan gears, and washing machine detergent dispenser wheels – faster cycle times (reduces mold cooling time by 15–20%) directly lower production cost per thousand parts.

4. Competitive Advantages

• Quality consistency: Lot-to-lot viscosity variation <±3% (ISO 1133), enabling predictable mold filling and reject rates below 0.5% in validated tools.

• Supply reliability: Triple-sourced stabilized production from ISO 9001:2025-certified facilities with 99.2% on-time delivery record over 18 months.

• Logistics capability: Regional warehousing in Asia-Pacific, Europe, and North America; 48-hour dispatch for sample quantities, 7-day lead time for full containers.

• Price competitiveness: Positioned at 5–8% below European homopolymer benchmarks while maintaining Japanese-equivalent purity.

• Sustainability: Production process recovers 94% of process water; material fully recyclable within closed-loop regrind systems (up to 25% regrind without property loss).

• Technical support: Full Moldflow® analysis database available; free of charge validation of temperature/pressure profiles for your specific mold geometry.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 1 metric ton (MT) for first trial order; 5 MT for repeat orders.

• BULK 20MT loading: Standard twenty-foot container packed with 800 × 25 kg bags (20 pallets, 1 MT per pallet).

• Capacity per 20′ container: Exactly 20 MT net weight (no hazardous cargo restrictions; UN2211 classification only for certain additives – not applicable to base POM 150 grade).
