What’s the Next Big Thing in Polyurethane?

I started my career in the polyurethane industry in the early 1970s.

Over the years I’ve seen many developments:

✅ The move from hot cure to cold cure moulding
✅ The rise of MDI-based systems
✅ HR and CMHR foam technologies
✅ The elimination of CFCs and other environmentally damaging blowing agents
✅ Significant improvements in processing equipment and controls

Yet, despite all these advances, the fundamentals of polyurethane manufacturing remain remarkably similar to those of 30 or 40 years ago.

Polyurethane remains one of the most versatile and cost-effective materials available, serving industries as diverse as automotive, aerospace, rail, furniture, construction and many more.

But where do we go from here?

Will the next breakthrough come from:

🔹 Sustainable and recycled raw materials?
🔹 Chemical recycling and circular polyurethane systems?
🔹 AI-driven process optimisation and smart manufacturing?
🔹 New fire performance technologies?
🔹 Advanced comfort engineering and smart seating?
🔹 Or could an entirely different material eventually challenge polyurethane’s position?

After more than 50 years in the industry, I’m not convinced we’ve seen the biggest innovations yet.

I’d be interested to hear from others across the polyurethane supply chain:

What do you believe will be the next major breakthrough in polyurethane technology?

And perhaps the bigger question:

Have we already seen the best of polyurethane, or is the industry’s greatest innovation still ahead of us?

MOCA has played a significant role in the development of high-performance polyurethane elastomers—but it’s also one of the industry’s most controversial curing agents.

WHAT IS MOCA?
4,4’-Methylenebis(2-chloroaniline) (commonly known as MOCA) is an aromatic diamine used primarily as a curing agent for MDI-based polyurethane systems. Introduced in the mid-20th century, it quickly became valued for producing elastomers with excellent mechanical strength, abrasion resistance, and durability.

APPLICATIONS
MOCA-cured systems have historically been used in demanding environments such as:

🔹Industrial wheels and rollers
🔹Mining screens and conveyor components
🔹Automotive and heavy engineering parts
🔹Seals, gaskets, and load-bearing elastomeric components

Its ability to deliver consistent hardness and strong dynamic properties made it something of a “gold standard” in cast polyurethane elastomers for decades.

HAZARDS & CONCERN
However, MOCA’s legacy is overshadowed by serious health risks. It is classified as a carcinogen, with exposure routes including inhalation, ingestion, and skin contact. Long-term occupational exposure has been linked to bladder cancer, leading to increasing regulatory scrutiny worldwide.

Handling MOCA safely requires strict controls:

✅Closed systems and automation
✅Comprehensive PPE
✅Rigorous workplace monitoring

Despite these measures, many regulators have concluded that the risks outweigh the benefits—especially given the availability of safer alternatives.

WHERE IS MOCA BANED?
The use of MOCA is now heavily restricted or effectively banned in several regions, including:

⛔️The European Union (under REACH regulations)
⛔️The United Kingdom (post-Brexit UK REACH alignment)
⛔️Increasingly restricted in parts of the United States under OSHA oversight.

Are you still using MOCA in your process and if so, what for?

THE FUTURE
Today, the industry continues to transition towards safer curing agents—balancing performance with worker safety and regulatory compliance.

👉 The question for manufacturers is clear: Are legacy materials like MOCA still justifiable, or is it time to fully embrace the next generation of safer alternatives?

Combustion Modified High Resilience (CMHR) polyurethane foam was developed in the UK in response to growing concerns over fire safety in domestic furniture during the late twentieth century. Prior to its introduction, standard flexible polyurethane foams—widely used in sofas, mattresses and seating—were found to present a significant fire risk, particularly when ignited by ci******es or small open flames.

A major turning point came with the introduction of the Furniture and Furnishings (Fire) (Safety) Regulations 1988. These regulations, brought into force in 1988 and subsequently amended, imposed stringent flammability requirements on upholstered furniture sold in the UK. Manufacturers were required to ensure that fillings and coverings could resist ignition and limit flame spread under defined test conditions.

To meet these requirements, the polyurethane industry developed CMHR foam. Unlike conventional high resilience (HR) foam, CMHR incorporates combustion-modifying additives—typically based on phosphorus or melamine chemistries—into the formulation. These additives promote char formation, reduce heat release, and slow flame propagation, enabling the foam to meet demanding tests such as the “Crib 5” ignition standard.

The early development of CMHR foam presented technical challenges. Initial formulations could negatively affect comfort, foam stability, or processing consistency. However, continued innovation in polyol design, additive systems, and manufacturing control has enabled producers to deliver materials that retain the key benefits of HR foam—resilience, durability, and support—while achieving the required fire performance.

Today, CMHR foam is widely used throughout the UK in domestic upholstered furniture, including sofas, armchairs, and mattresses, and is also specified in certain contract seating applications. Its success reflects a careful balance between regulatory compliance, safety, and end-user comfort.

Looking ahead, increasing pressure to reduce emissions and eliminate certain flame retardant chemistries is likely to drive further innovation. Will the next generation of CMHR foams rely on reactive, non-migrating technologies or entirely new material systems to meet both fire and environmental demands—and what will this mean for performance, cost, and processing?

After over 50 years working with moulded PU foam, I’ve noticed something interesting:

Most production problems are not caused by “big failures”…

They come from small, repeated issues:

▶️ Density variation that no one fully explains

▶️ Scrap rates that are “accepted as normal”

▶️ Moulding inconsistencies that come and go

▶️ Formulations that work… until they don’t

And in many factories, these problems quietly cost hundreds of thousands each year.

What I’ve learned over the decades is this:

👉 The difference between an average operation and a high-performing one is not equipment
👉 It’s not raw materials
👉 It’s technical understanding + consistent control

The challenge?

Most companies don’t need (or can’t justify) a full-time senior technical director. So I’m exploring something new:

A way to provide ongoing, hands-on technical support remotely —

working alongside production teams to:

Reduce scrap

Stabilise processes

Solve recurring issues

Support new developments

Not as a one-off consultant, but as a continuous technical partner.

The objective would be simple:

👉 Any investment in this support should be recovered through measurable savings and efficiency improvements.

I’m curious:

If you’re involved in moulded PU foam, what’s the most persistent production issue you face today? Or what’s one problem you’ve “learned to live with”?

I’d be very interested to hear real-world experiences.

And if this kind of ongoing technical support sounds relevant to your operation, feel free to message me.

When I first stepped into the polyurethane foam industry back in 1973, my journey began with a company specialising in TDI-based hot cure moulded cushions.

At the time, this was a well-established process — robust, reliable, and widely used across automotive and seating applications. The chemistry, the tooling, and the discipline required on the shop floor made it a fantastic grounding for a young engineer. You learned quickly that consistency wasn’t optional — it was everything.

Over the years, we’ve seen significant evolution in materials and processing. Cold cure systems, MDI-based technologies, improved catalysts, and more sophisticated moulding techniques have largely taken centre stage. These advances have delivered better comfort, faster cycle times, and improved environmental profiles.

But it got me thinking…

What happened to hot cure moulded cushions?

Are they still being produced anywhere in the world today?
If so, in what applications — and why?

Is there still a place for TDI hot cure systems in modern manufacturing, or have they been completely replaced?

I’d be really interested to hear from others in the industry:
👉 Have you worked with hot cure moulded foam?
👉 Are you still running these systems today?
👉 Or are they now purely part of polyurethane history?

It’s always fascinating to reflect on how far we’ve come — and whether some of the “old ways” might still have relevance.
