In the pigment industry, Lithopone has long been considered a "classic" material. Although many high-end applications today rely on Titanium Dioxide, you'll still find that Lithopone 28% continues to hold a solid position in several industries. The reason is actually quite simple: in many cases, companies don't need the best performance-they need something cost-effective and reliable.
Let's break it down in a more practical way and see why some industries still choose Lithopone 28%.
1. Strong Cost Pressure Makes "Value for Money" More Important
A common question is: if titanium dioxide performs better, why not fully replace lithopone?
In reality, many manufacturers-especially those producing high-volume goods like plastics, rubber products, and economy-grade coatings-operate on tight margins. Switching entirely to TiO₂ would significantly increase production costs and reduce competitiveness.
That's where Lithopone 28% pigment price advantages come in. It is much more affordable and can partially replace titanium dioxide in formulations, helping reduce overall costs without causing a noticeable drop in product performance. This is especially important in export markets and price-sensitive regions.
2. "Good Enough" Performance Is Often All That's Needed
It's true that lithopone has lower opacity, weather resistance, and UV stability compared to TiO₂. However, many applications simply don't require top-tier performance.
For example:
- Interior wall coatings (not exposed to strong sunlight)
- Everyday plastic products
- Rubber items with limited service life
In these cases, a moderate level of whiteness and opacity is sufficient. That's why applications like Lithopone 28% for interior paint remain very common.
In simple terms:
👉 If an 80% solution solves the problem, there's no need to pay for 120%.
3. Easier Processing and Better Production Stability
From a manufacturing perspective, ease of processing matters just as much as performance.
Lithopone offers good dispersion and stable processing behavior, making it easier to handle during production. This is particularly beneficial for factories that may not have the most advanced equipment.
It is widely used in:
- PVC pipes and profiles
- Injection-molded plastic products
- Rubber compounding
In these processes, materials like Lithopone 28% for plastics and PVC applications help improve consistency and reduce defect rates.
4. Supply Stability Matters More Than Peak Performance
Another often overlooked factor is supply chain stability.
Titanium dioxide prices can fluctuate significantly, and supply shortages do happen. In contrast, lithopone production is relatively stable, with more predictable availability.
As a result, many manufacturers adopt a blended approach (TiO₂ + Lithopone 28%) to:
- Control raw material costs
- Reduce supply risks
- Maintain acceptable product performance
This strategy is especially common in large-scale production sectors such as construction materials and packaging.
5. In Some Applications, It's Actually a Better Fit
In certain cases, lithopone is not just a substitute-it's the more suitable option.
For example:
- Rubber industry: requires good filling properties and flexibility
- Textile industry: used as a delustering agent
- Artificial leather and flooring: focus on cost and basic appearance
These applications prioritize overall formulation balance rather than maximum optical performance. That's why Lithopone 28% for rubber and coating industry continues to see stable demand.
6. Safety and Environmental Considerations
Compared to older pigments that contained lead, lithopone is considered a relatively safe and non-toxic white pigment. For products that require safer formulations but still need to control costs, it remains a practical choice.
While high-end environmental standards often favor titanium dioxide, lithopone still has room in mid- to low-range markets.
Final Thoughts
So why do some industries still choose Lithopone 28%? The answer comes down to three key factors:
- 💰 Lower cost for large-scale production
- ⚖️ Performance that is "good enough"
- ⚙️ Stable processing and reliable supply
As a result, it remains widely used in:
- Economy-grade coatings
- Plastics and PVC products
- Rubber manufacturing
- Packaging and construction materials
Looking ahead, titanium dioxide will continue to dominate high-performance applications. However, cost-effective materials like Lithopone 28% are unlikely to disappear anytime soon, especially in price-sensitive industries.
